Royal Revenues and Indian Population in New Spain, ca. 1620-1646

Introduction

In a series of earlier studies, we examined materials on the Indian population of central Mexico and made calculations of numbers based upon our analysis of those materials. We have thus been able to present estimates for various years in the sixteenth and the first decade of the seventeenth centuries. For the convenience of the reader we list them:

These are based upon samples whose extent and ease of interpretation vary considerably. The estimate for 1568, the most firmly based, derives from a sample of perhaps 90% of the towns in central Mexico, which were newly counted in terms of a reformed and relatively uniform classification of tributaries and half-tributaries. That for 1605 is based upon a small sample of towns whose populations had shrunk so badly that they were relocated in new larger towns under the policy of congregación .^[1]

At the other end of the colonial period, calculations of Indian population are comparatively simple for various years of the eighteenth century, since tribute counts for that century are

frequent and careful, and the viceregal administration was making the first attempts at general civil censuses. So for the eighteenth century, scholars have abundant material, subject to the new problems that arise from the increasing number of racial mixtures in the population and the growing confusion in the application of social and racial criteria to them.^[2]

The span of years from 1610 to perhaps 1700, in contrast, has presented a gap in evidence. Yet those years contain the point at which the Indian population of central Mexico reached its nadir and began to recover from the long decline unleashed by the European Conquest. Our difficulty, like that of other students, has been to find materials that under treatment could provide evidence. In recent years a number of papers have appeared that offer partial or regional approaches to the problem. In August 1962, in a paper read at the XXXV International Congress of Americanists in Mexico City, José Miranda presented comparisons of prevailing tribute assessments for a number of towns in the bishoprics of Mexico, Puebla, and Michoacán for two periods in the seventeenth century: 1644–1657 and 1692–1698. He found them in accounts of the half-real for cathedral construction (medio real de fábrica ) levied annually on every Indian tributary and directly convertible to the prevailing tribute assessment. There was no indication of the precise year when the assessments were made. Miranda's material showed a substantial increase in Indian population, on the order of 28%, between assessments in force in 1644–1657 and in 1692–1698. He conjectured that the low point of the Indian population came in the 1620's or 1630's.^[3]

Subsequently, in our study of the historical demography of one small region in central Mexico, the Mixteca Alta, published in 1968, we made use of the Montemayor y Córdova de Cuenca count of that region in 1661, found in the Archivo General de Indias, in Seville. Analysis of the count indicated that the nadir of Indian population in the Mixteca Alta probably came in the decades 1600–1620 at a value of from 20% to 25% of the population in 1569, and as little as 3% or 4% of the pre-Con-

quest level. The Montemayor y Córdova de Cuenca report also gave the dates of the previous counts and so provided the first clear evidence of the extent to which prevailing accounts should be adjusted to an average year some time back.^[4]

Another study, which we published in 1971, of the population of west-central Mexico, 1548–1960, indicates that the low point of Indian numbers in that region occurred around 1650, with a value of slightly over 12% of that for 1548 and 33% of that for 1570.^[5] Much of west-central Mexico, however, was conquered and settled later than central Mexico. Moreover, it remained essentially a frontier area until late in the colonial period. Accordingly, the experience of west-central Mexico cannot be extrapolated directly, without adjustment, to central Mexico.

More recently, a study by Günter Vollmer on Indian towns in southern Puebla sets the low point of the Indian population at approximately 1650, when he estimates it to have been 27% of the value for 1570.^[6] Another study, by Claude Morin, of Santa Inés Zacatelco in the Puebla basin suggests also that the low point of population in central Mexico occurred around 1650, with perhaps 816,000 Indians.^[7] A more general study of central Mexico in the seventeenth century, by J. I. Israel, holds that "the Indian population of central Mexico, having fallen to a level of between 1 1/2 and 2 million in 1607, continued to decline at least until the middle of the century." Increase did not become manifest until 1671.^[8] So the effort to fill the gap has continued, with fair agreement that the low point of the Indian population came in the seventeenth century, although there has

Israel cites the estimate of Landeras de Velasco, 10 January 1607, that there were 344,000 full tributaries, presumably in the Audiencia of Mexico without Yucatan. Israel must be using a multiplicative factor of close to 5.0 to estimate total Indian population, for at the factor we have established on the basis of very careful inspection of evidence (2.8), the total Indian population would be 963,200. Even with adjustment to include the Indians of Nueva Galicia, the total, using the factor of 2.8, would not reach a million. See Cook and Borah, Essays , I, p. 309, for estimates of Nueva Galicia.

been no agreement on a more exact placing of the point within that span of years nor on the value to be assigned to the Indian population at that point. Our own two studies, it will be noticed, differ on placement of the point, admittedly for two very different regions.

Clearly the resolution of this question required more data in the form of counts of Indian population in the early and middle decades of the seventeenth century. Since there had been available as yet almost no tribute counts for that period, we turned to another possible source of information in the records of the pastoral inspections of bishops, some of them published, others unpublished but available in manuscripts. Unfortunately, those for the seventeenth century did not give adequate information on numbers of Indian tributaries, total population, or some group in the population that would give a clue to total number.^[9] So this attempt met a dead end.

Ideally, we wanted a set of counts taken in a relatively short period of time and covering all of central Mexico, either like the Montemayor y Córdova de Cuenca count for the Mixteca Alta or those of the tribute reform of the 1560's. In the absence of the ideal, we could use a statement of prevailing assessments, like those in the encomenderos' petition of 1597, but would have to understand that the data referred to the time when each count was made and that an average year should be calculated to adjust for the lag in the set as a whole. In 1958–59 Woodrow Borah spent a sabbatical year in Spain for the purpose inter alia of hunting for just such material. The search turned up the Córdova de Cuenca count and a great deal of eighteenth-century data, but only a few scattered town counts for the rest of central Mexico. After that and searches in Mexico, we had decided that the hunt would have to be left to the next generation of scholars exploring as yet ill-known reaches of the Archivo General de Indias, the bodega of the Archivo General de la Nación in Mexico City, or the largely unknown private archives of Spanish noble families, few of which in 1958–59 were open to scholars. Then, literally out of the blue, an airgram dated October 24, 1971, came to Woodrow Borah from E. William Jowdy, then a graduate student at the University of Michigan and doctoral candidate under the guidance of Charles

[9] Many records of pastoral inspections are valuable sources of demographic data. See Cook and Borah, Essays , I, chap. 1, esp. pp. 47–48.

Gibson, doing archival research in Madrid. Jowdy reported finding a document in the archive of the Duques del Infantado which gave much information on royal revenues and tribute assessments in the Audiencia of Mexico in 1646. A reply by return mail indicating that the find might be very important brought a generous offer to try to secure a film copy for our use. Jowdy brought the matter to the attention of the Duque del Infantado through the good offices of the latter's sister, the Reverend Mother Cristina de la Cruz de Arteaga, whereupon the duke graciously gave full permission to film the document and use it in any way.

The document of thirty-three folios is found among the papers of the Conde de Salvatierra, viceroy of New Spain from November 1642 to May 1648, when he moved to Peru. It forms folios 148–180 in volume 54 of the archive, the entire volume being correspondence and reports of various kinds of the Conde de Salvatierra for the years 1645–46^[10] The document consists of a one-folio letter of transmittal and thirty-two folios of report, both dated at Mexico City 4 September 1646, and signed by Juan de Cervantes Casaus, Contador Mayor of the Tribunal de Cuentas.^[11] It is addressed merely to an excelentísimo señor , who could be either the viceroy or the visitador-general, Juan de Palafox y Mendoza, but since the closing paragraph of the report states that it was prepared at the express command of the visitador-general, it seems probable that the report and covering letter are addressed to him. On the other hand, since the document is among the Salvatierra papers, it may be that we deal here with a second clean, signed copy prepared for the viceroy as well. The personal papers of both men have become part of the archive of the Duques del Infantado.

It is worth recalling here that the Palafox visita, a remarkably stormy one, occurred during years of unusual strain for the monarchy in Spain—continuation of the Thirty Years' War, the dissolution of the Crown Union with Portugal, and the revolts

of Catalonia and Naples—and of perhaps the low point of decay and inefficiency in royal administration in New Spain. The royal government was in ever greater need of funds just when the treasury in the Audiencia of Mexico found that local costs absorbed almost all local revenues. New taxes, such as stamped paper, were imposed, but were just coming into yield in 1646. On royal command Palafox removed one viceroy, the Marqués de Villena, a relative of the Duke of Braganza and new King of Portugal, through fear of disloyalty, and governed the colony until the arrival of the Conde de Salvatierra. In the end, the political storms arising from attempts at church reform delayed attempts at reforming civil administration, despite the cooperation of Salvatierra and Palafox in finding funds for remittance to Spain. Salvatierra was promoted to be viceroy of Peru; Palafox was recalled to Spain shortly afterward and left Mexico in June 1649.^[12] A normal element in any general inspection would have been a review of the royal finances; in the special circumstances of the Castilian monarchy in the 1640's, one was especially necessary and incumbent upon both visitador-general and viceroy. The report of 1646 was at least part of such a review.

The closing paragraph of the report clearly states that the review was ordered by Palafox, at what date we have no clear indication. The covering letter asks pardon for delay in preparing the report, blaming the delay upon burden of work and upon the difficulty of obtaining precise figures, since collections of royal revenues in the provinces (alcaldías mayores ) were sometimes placed in charge of the governors and sometimes entrusted to others at the decision of the Comptroller of Tributes and Sales Tax. The report, therefore, must have been asked for some months or even years before the date it bears. Preparation, even in terms of the leisurely processes of that period, was delayed and made difficult by the complex subdivision of administration of royal finance, which defeated any attempt at centralized supervision and accounting. The amounts due as royal tribute, one of the principal sources of revenue, could be ascertained by consulting the assessments of the Indian towns; but, without resort to the Comptroller of Tributes and Sales Tax, there was no way of determining amounts paid and in

arrears, the latter a considerable sum. The yield of taxes leased out could be ascertained easily, and averages estimated for some revenues of variable yield, directly administered by the Crown, such as the state monopoly of mercury and other taxes upon mining. Even so, the clerks collecting the material worked with surprising negligence, since, as we shall see, they passed over the folios of tribute assessments for a large number of Indian towns. The report is a substantial sample rather than a full statement. It is, nevertheless, a remarkable view of the royal finances in the Audiencia of Mexico for what were probably the years of most corrupt and inefficient fiscal administration during the entire colonial period. In the 1650's there was a drastic overhaul of the administration of Indian tributes and the royal monopoly of mercury after a quarter-century of virtual paralysis.

We now discuss the report under the rubrics of data on Indian population and the royal fiscal system.

2—
Indian Population

The initial determinations that must be made are how complete is the coverage of the data on Indian tributaries—i.e., how many towns are represented in the report and what is their proportion to the total number in the Audiencia of Mexico at the time; and further, what year should be set as the average date for the counts on which the assessments were based, since all of them must have been made some time before the formal tribute was set and an even longer interval before the listing in the report. Let us start with the second matter.

In terms of mid-sixteenth-century town boundaries, there are approximately 740 towns in the 1646 list. The statements of tribute for towns held by the Crown give the amounts due under the standard tribute assessment of money, maize, cacao, cotton cloth, etc.; the amount of money due as servicio real , an additional tax of four reales per tributary; and usually an additional statement on the number of tributaries found at the count on which the assessment was based. For example, the statement on Atoyac finishes "respecto de tener ciento y quarenta y tres tributarios" ["since it has 143 tributaries"]. For towns held partly by the Crown and partly by an encomendero, the statement of standard tribute usually covers only the share of the Crown, and so it is the servicio real and statement of

number of tributaries that provide the data. For towns held entirely by encomenderos, there is usually no statement of standard tribute or number of tributaries; but the servicio real, which was levied on all Indian tributaries whether in Crown or encomienda towns, is given, and since it had a standard relation to the number of tributaries, is directly convertible to the number in the prevailing assessment.

There is unfortunately no statement in the report on the date when the assessments were made. Nor is it likely that the interval between the date of the count and the report was so short that we may ignore the matter. For, in the closing years of the sixteenth century, the rhythm of recounts and reassessments began to slacken and the intervals between counts to lengthen. In the neighboring Audiencia of Nueva Galicia, a survey of tributes in 1594 reported that in that treasury jurisdiction, Crown towns were paying under assessments made an average of nine years five months earlier, and that for the six towns reassessed in 1594 the average interval to the preceding count was fourteen years one month.^[13] Nueva Galicia was a separate treasury jurisdiction, although in general it followed the lead of the Audiencia of Mexico. Accordingly, its experience is no more than an indication. We do know that in the second quarter of the seventeenth century the administration of tributes in the Audiencia of Mexico was under an unusually fraudulent and inept administration. In 1653 charges were brought against the Comptroller, and the entire administration eventually was shaken up and reorganized. One of the failures of the Contaduría General de Tributos in that period was in carrying out recounts and reassessments—some indeed were made, but few.

The most useful testimony we have for the Audiencia of Mexico is that of Montemayor y Córdova de Cuenca about the Mixteca Alta in 1661. His reporting gave the dates of previous tribute counts, and inter alia has enabled us to determine that the 1646 report embodies the latest count up to 1646 for the towns of the Mixteca Alta. The average interval between time of assessment and the reassessment by Montemayor y Córdova de Cuenca in 1661 was thirty and a half years.^[14] One cannot

subtract fifteen years (1661–1646) from this average and apply it without further adjustment, for in the reporting for the Mixteca Alta there are a number of towns counted and reassessed after 1646 which bring down the average. The intervals between those counts and the preceding ones would raise it. Neither can we apply the thirty and a half years without downward adjustment, for Indian towns nearer Spanish centers may well have been counted and reassessed more frequently than those in the Mixteca Alta; and the lag in recounts must have built up at some time after the period in the second half of the sixteenth century when recounts were frequent. An average lag of thirty and a half years probably represents the low point of tribute administration. The adjustment we must make is thus fifteen years plus another term of years ranging from five to ten, a total of twenty to twenty-five. The average date of the assessments in the 1646 list should be set somewhere between 1620 and 1625. If the reader demands a single year, 1622 or 1623.

The other matter to be determined here is the extent to which the 1646 list covers the Indian towns of the Audiencia of Mexico. Our basis for comparison is the assessments of the tribute reform with an average date of 1568, which give us our fullest list with least adjustment. Indian towns in the Audiencia of Nueva Galicia would automatically be excluded because they lay in another treasury jurisdiction, that of Guadalajara. Similarly, Tabasco would be excluded because it lay in the subordinate but separate government of Yucatán. Its Indian tributes were administered by the subcaja of Santa María de la Victoria, reporting to the caja of Mérida, for Yucatán was also a separate treasury jurisdiction. These automatic exclusions remove from either list some hundreds of towns of the approximately 2,000 which existed in the early sixteenth century in central Mexico as we have defined it. Another group of towns on neither list is those that went out of existence in the first half-century of Spanish rule. In all, the 2,000 towns would come down to perhaps 1,400.

Comparing the two lists is also complicated by the changes of the nearly eighty years separating them. During that long interval, shrunken towns were consolidated through congregación; settlement shifted within the territory of towns remaining formally intact; within other towns dependent units (sujetos ) be-

came autonomous, for they saw no reason to continue in a status of dependency forced upon them by former rulers when the current overlords were willing to annul it; in some regions where population almost vanished, new towns were created; and in the zone to the north which had been the territory of nomadic Indians in 1520, the Spanish founded new settlements.^[15] The identification of relationships and shifts has been a detective job of considerable difficulty. One surprise has been the uncovering of a substantial number of towns on the 1646 list which we knew existed in the first half of the sixteenth century, but thought had gone out of existence by the 1560's. In terms of number of towns, we may tabulate our findings:

Relative to the 1568 list there is, then, a coverage of approximately 50%; in terms of the number of towns in the district of the royal treasury of Mexico City, the 1646 list gives information on 54%.

Another way of approaching this determination is in terms of proportion of aggregate population involved in coverage and omission. The best approach here is to compare the aggregate population reported by the 1646 list with that calculated by ratio through comparison with the 1568 list. (We jump to our results here; the detail is in Table 1.2, part C.) For the plateau, the omission is 18.6%; for the coasts, 37.0%; for the district of the caja of Mexico City as a whole, 24.1%. In other words, the 1646 list reports 75.9% of the reconstructed total population, and in these terms is an even better sample. The difference in the findings by number of towns and aggregate population is easily explainable as due to a tendency to pass over smaller rather than larger towns in preparing the 1646 list.

The omissions from the 1646 list cast further light on the way the Contaduría de Tributos kept its records of Indian tribute counts and assessments. We know through the discovery

and publication of a substantial part of the second colonial set of such records that they were kept in looseleaf fashion. The records of a single town, especially if important; of towns held initially by one encomendero, even if dispersed geographically; or of contiguous towns were entered on a single folio or group of folios. We do not know how these were filed in relation to each other, for the present alphabetical order of the records, manuscript and printed, reflects a recent arrangement of the scattered folios discovered. The second colonial matrícula de tributos was superseded in the 1570's, presumably by copying off the latest assessments on fresh folios to form a new set of records.^[16] The 1646 list may have been taken from the third colonial matrícula de tributos, or even a fourth one, although the slowing down of tribute reassessments suggests that the creation of a fourth set by 1646 was unlikely. The 1646 list indicates that there was a tendency to file together the folios of town assessments for a single region. The partial listing together of towns in the Zapotecas, the Veracruz coast, Colima, etc., can only have come about in this way. We may surmise that the tribute records of many towns in 1646 were filed together by alcaldía mayor, but that systematic grouping by province was to wait until the eighteenth century. The order of towns in the 1646 report, as well as the omissions in it, must arise either directly or at one remove from the perhaps hasty work of a scribe taking off the information from the folios of the Contaduría de Tributos. It was easy to miss folios, especially if the assessments for any group of towns ran to more than one folio so that it was necessary to locate the end of one set of records and the beginning of the next.

Let us turn now to our procedure in taking off and using the information in the 1646 report for calculating Indian population. Our first step was to identify the towns one by one, ascertain their geographical location and their identity or relation to towns on the 1568 list, include data for 1595 where possible, and prepare working charts by region. The regions were automatically those we had laid out for our calculations of population in the sixteenth century.^[17] The data for Indian population in 1568 and 1595 had been segregated previously

and published for those regions.^[18] As we have already suggested, identification of the towns involved a long series of problems in detection. Many towns in Mexico have identical names; others have nearly identical ones, which in the more haphazard spelling of the seventeenth century become identical. Here the tendency of the 1646 report to list together contiguous towns or towns of one region helped very greatly. Changes brought by the nearly eighty years between 1568 and 1646 also created serious problems of identification, for many towns had changed their names, or moved the location of the main settlement within their territory, sometimes keeping the name and sometimes taking on the name associated with the new site; others had become consolidated; others were sujetos of towns in 1568, but had since become autonomous and dealt directly with Spanish authorities; others represented new settlement on abandoned land—a phenomenon particularly of the lower altitudes; yet others were new settlements within what had been nomadic Chichimec territory in 1520, but was being brought under control by the Spaniards. In all probability, the task of identification would have been impossible for at least a quarter to a third of the names if we had not been able to use the newly published A Guide to the Historical Geography of New Spain by Peter Gerhard. This remarkable volume, organized by the alcaldías mayores of the eighteenth century, permits tracing the territorial history and changes of towns in the district of the treasury of Mexico City. It even gives the history of encomiendas and parishes. In the end, we were unable to identify and locate just three of the towns in the 1646 list.

Once towns in the 1646 report were segregated by region and listed with information, where possible, on population in 1568 and 1595 and numbers of tributaries in 1646, the second step was to convert tributaries into total population. We have explored at considerable length elsewhere the problems and evidence for arriving at appropriate multiplicative factors for various years in order to convert tributary number into total Indian population.^[19] There is accordingly no need to repeat the

exploration here. For 1568 and 1595, our data already applied the factor of 2.8 (which implies a factor of 3.3 for a married man or casado ). That value, although low, is derived from a substantial mass of evidence and must be regarded as solidly based. It is, however, clearly inapplicable to a later period when the number of tributaries reached nadir but demographic changes within the Indian population were preparing the way for the fairly steady increase that was characteristic from some time in the first half of the seventeenth century to the end of the colonial period. Equally, the relatively high factors necessary for conversion of eighteenth-century tributary numbers to total Indian population, although they are very firmly based on a substantial mass of data—some of the best we have for Mexico at any time—cannot be applied to the years in the seventeenth century when the population was in transition from one demographic pattern to another. Accordingly we returned to our explanation and the graph in our study of the population of the Mixteca Alta and chose 3.4 as the most appropriate value for application to the data in the 1646 report, understanding that the data should be regarded as falling in the years 1620–1625.

We had hoped to verify our calculations further by a comparison of the data in the 1646 report with the tribute counts of the early eighteenth century, approximately 1715–1733, for which there survives an unusually full series of new counts for the treasury district of Mexico. The appropriate factor for converting tributaries to total Indian population for those data would be 3.8. Unfortunately for our needs in this study, the eighteenth-century tribute counts and assessments were made under a new system which handled a province at a time. Comparison on any extensive basis with earlier counts and assessments by individual towns accordingly required so much adjustment that we abandoned the attempt.

Our next steps were to rearrange the regional data on new worksheets, breaking down the regional division into further categories which we applied uniformly to the eleven regions (which are numbered from I to X, with a IIA). For each region, Table 1.1, part A for that region lists all towns or other places which occur on both the 1568 and 1646 lists. From the total of these we have calculated the ratio of the two populations 1646/1568. Table 1.1, part B for the region gives the names of places which occur in the 1646 reporting but are not on the 1568 list. The aggregate of these populations must be added to

the regional total in order to calculate the percentage of deficiency in the 1646 reporting for the region. Table 1.1, part C for each region gives the names of places for which only the 1568 list has a value, i.e., they are missing from the 1646 list. We have not included towns or places for which we had calculated hypothetical populations for 1568 on the basis of information of earlier date. The numerical weight of places with a population value in 1568, but not in the 1646 reporting, can be estimated by dividing the total of their population by that of the entire region. The resulting value, expressed as a percentage, gives an index to the degree of deficiency found in the 1646 reporting for the region.

Since the population reported in the 1646 list is deficient in all regions, the probable true population must be calculated. An estimate may be obtained by the use of simple proportions based upon the logical assumption that the mean ratio found for each region from the paired values for places in Table 1.1, part A holds equally for each region for the towns in Table 1.1, part C for which we have no information in the 1646 reporting. Since the proportion of places for which we have information in each region is large—for some regions very large—the ratios, although not absolutely precise, are reasonably close to the true value. We then applied the ratio for each region of the population reported in the 1568 data for that region to the totals in parts A and C. The resulting value is the reconstructed Indian population of the region in 1620–1625 (our adjusted average date for the tribute assessments).

As a check upon the results secured by comparing the data in the 1568 and 1646 reporting, we have turned to the data of average date of 1595. For each region, Table 1.1, part D shows the towns for which we have data in the 1568 and 1595 reporting, together with the ratios 1595/1568. We determine the mean ratio and apply it to the total Indian population of the region in 1568, a procedure which yields an estimated population for the entire region in 1595. A similar operation is performed with those towns of each region for which we have population figures in both the 1595 and 1646 reporting. The numerical values and ratios of 1646/1595 are in Table 1.1, part E for each region. In all cases, the populations in 1595 calculated from those in 1646 are smaller than the populations calculated from the 1568 data. This difference, or deficiency, in

the values calculated from 1646 confirms the result of direct, town-by-town comparison of 1568 and 1646.

We turn now to the analysis of the data region by region. Our explanation is deliberately arranged to be as uniform as possible for each region, in accordance with the uniform organization of the data.

Region I

The Central Plateau, a culturally homogeneous area that was the core of ancient Mexico at the time of the Spanish Conquest and still has substantial unity today. On the north, the boundary is the Chichimec frontier of 1550. On the east, it is the Atlantic escarpment at approximately the contour line of 1200 meters to the meeting point of the state boundaries of Veracruz, Oaxaca, and Puebla. On the south, the boundary runs along the Balsas River, including the south bank, as far as Michoacán. From there it runs north along the Mexico-Michoacán state line and then east along the Hidalgo-Querétaro state line to the Moctezuma River.

We find 206 places, not necessarily towns, which occur on both the 1568 and 1646 lists. In 1568 the population of these 206 places is 1,321,329; in 1646 it is 303,717. The ratio 1646/1568 is 0.230. (See Table 1.1, Region I, part A.)

Part B of the table for Region I shows 21 places found on the 1646 list which had to be omitted from part A because the name did not appear on the 1568 list, because the place was part of another town for which no population was given, or for various other reasons. The total population of these 21 places is 9,662, making the total for the 1646 list 313,379. Of this, the population deleted (9,662) is only 3.1%, an insignificant amount. We conclude, therefore, that the 1646 reporting for Region I, within plus or minus 3%, can be found in the 1568 list, and that the population ratio of 0.230 for these places is valid.

Table 1.1, Region I, part C gives the names of 125 places which occur in the 1568 list but are not found in the 1646 reporting. Some of these are of considerable size and cannot possibly have been depopulated or lost in congregation between the two dates; for example, Metztitlán and Tulancingo in Hidalgo; Acolmán, Amecameca, and Oxtotipac in the state of Mexico; Tacubaya and Churubusco in the Distrito Federal; and Tecamachalco in Puebla. The only explanation is that the 1646 reporting is incomplete and that a relatively large number of towns has been omitted. The total population in 1568 of the 125 places which are missing from the 1646 reporting is 396,306. The aggregate for 1568 would be 1,321,329 plus 396,306, or 1,717,635, of which the towns missing in the 1646 report would account for about 23%.

We may calculate the probable true population of Region I in 1620–1625 (our estimated average date) simply by using proportions and assuming that the ratio between the two sets of data was the same for all towns alike (in totals). This would mean that 1,717,635 × 0.230 = 395,056. The latter figure should be taken as the population of Region I in 1620–1625.

The data in the 1595 list may serve to verify our calculations for the other two dates and, in turn, may be verified by them. Table 1.1, part D shows the population of 119 places in 1568 and 1595. The total of the former is 668,867 and of the latter 332,256. The ratio 1595/1568 is 0.497. By proportion, the entire population of Region I in 1595 would be 1,709,793 × 0.497 = 849,767. Table 1.1, Region I, part E shows similar data for 1595 and 1646, with 81 places. Here the totals are respectively 231,140 and 93,572, and the ratio 1646/1595 is 0.405. The entire population of Region I in 1595, calculated from the total in the 1646 reporting (313,379 as above), would be 773,775. The two results differ by 10% but, allowing for omissions in the 1646 list, are remarkably close.

Region II

Valles–Pánuco. This is the coastal plain and foothills of the Huaxteca from southern Tamaulipas to northern Veracruz as far south as latitude 20°N. There are 28 places which occur in both the 1568 list and the 1646 list. In 1568 the population of these 28 places is 35,316; in 1646 it is 8,559. The ratio 1646/1568 is 0.242. The data are given in detail in Table 1.1, Region II, part A. Part B shows 9 places found in the 1646 report which had to be omitted from part A. The total population of these 9 places is 353, making the total for the 1646 list 8,912. Part C shows 122 places which occur in the 1568 list but which are not found in that for 1646. The total 1568 population of these 122 places is 37,818. The aggregate for 1568 would be 35,316 plus 37,818, or 73,134, of which the towns missing in the 1646 list would account for 52.2%.

We may calculate the probable true population of Region II by using proportions and assuming that the ratio between the two sets of data was the same for all towns alike (in totals). This would mean that 73,134 × 0.242 = 17,698. The difference between this value and that of the 1646 list (8,912) is very great and may invalidate the assumption. It may be necessary to assume additionally that many of the places on the 1568 list disappeared before 1646.

Table 1.1, Region II, part D shows the population of 22 places in 1568 and 1595. The total of the former is 26,991 and of the latter 23,752. The ratio 1595/1568 is 0.880. By proportion, the entire population of Region II in 1595 would be 73,134 × 0.880 = 64,358. Part E shows similar data for 1595 and 1646, with only 5 places. Here the totals are respectively 14,087 and 5,039, and the ratio 1646/1595 is 0.358. The entire population of Region II in 1595, calculated from the total in the 1646 data (8,912 ÷ 0.358), would be 24,894. The two results are discrepant, a fact probably referable to the disappearance of many small towns in the region.
