2.2. Analysis of historical data sources on population
2.2.1. Background
In case of Estonia, written sources on population date back to XIII century, starting with the famous Liber Census Daniae. These sources are written in Latin, German, Russian, Swedish and Polish and we may find them in the archives of Estonia, Sweden, Russia and Poland.
From the second half of the XVII century the first parish registers in rural parishes of Estonia appear. Starting from 1686, all parishes were obliged to introduce registers on baptisms, burials and marriages, based on the ecclesiastical law of Swedish king Karl XI. Although part of early registers were destroyed during the Northern War (1700-1721), 39 parish registers from the XVII century have survived till our days, for the period 1712-1799 registers from 89 parishes in the archives and from 1834 registers are available for all parishes. It is important to note, however, that differently from Sweden and Finland, no vital statistics was compiled on its basis until the second half of the XIX century.
Another major source is land- and soulrevisions. Landrevisions from the XVI and XVII centuries and description books from period 1680-1710 include information mostly on the number of households. From 1712 start the series of landrevisions where the number of inhabitants of peasants’ households (divided by sex and children-adults) is recorded. In the series of soul revisions 1782-1858 all persons, excluding some privileged strata, were recorded by name and age.
Yet another source – books about persons – something like status animarum has survived in XVIII century in some parishes, from 1834 onwards in nearly all parishes. In these books the inhabitants of the parish are recorded household by household and family by family. The first census, covering the whole country took place in 1881, preceded by local censuses of urban populatin in 1867 and 1871, marking the modern era in population data collection in Estonia.
As these sources differ in origin, content and structure, their application requires special efforts. The second subtheme unites source-critical and source-analytical research work to understand the methodological background and archival history of the sources, the possibilities to establish links between the sources of different provenance etc. The main objective of research under the subtheme is to transform the historical records into data which can be analysed by the methods of quantitative and qualitative analysis developed and/or applied in historical demography, including the techniques of family reconstitution. Also are the development, harmonisation and interpretation of metadata of sources relevant for historical demography have been included under subtheme.
During the reporting period, research under the subtheme has been conducted in four main directions: (1) development of finding aids and references to historical population data sources preserved in different archives, (2) record-linkage between population data sources of different type and origin, (3) record-linkage between population data and geo-spatial records and (4) development of integrated databases on historical populations and the application of family reconstitution method.
2.2.2. Subtheme frameworks
2.2.2.1. The principal project frameworks include three projects supported by Estonian Science Foundation, Open Estonia Foundation and Governmental Commission for Population and Social Statistics. Methodologically and technically, all the referred projects were closely integrated.
2.2.2.2. The interdisciplinary nature of the subtheme implied the participation of historians, demographers, geographers and archivists. Partners cooperating under subtheme have come from history and geography departments of Tartu University, National Archives, Tallinn City Archives etc.
2.2.2.3. Research and activities under the subtheme have generated a computerised data archive, including individual records for more than 100 thousand persons in the period 1700-1900; the data archive is structured in form of relational database; additionally aggregate tables for the same period, published as well as unpublished have been computerised, including the set of tabulations from the 1881 and 1897 censuses, statistical reviews from the second half of the XIX century etc. Compiled descriptions of population sources (metadata) are available and accessible in the National Archives.
2.2.2.4. The results of research and activities under the subtheme have been applied for curricula development at history department of Tartu University, supported by grants from university and Open Estonian Foundation. In this framework, programme and facilities were developed for seminars to give the students the overview of and experience of working with historical population sources. The results have been presented in several workshops, for international audience by Robert Schweizer [Datenbanken über Deutschbalten aus der PRPD-Gruppe an der Universität Tartu. Der Finnische Meerbusen als Brennpunkt. Wandern und Wirken deutschsprachigen Menschen in europäischen Nord-Osten. Helsinki, 1998] as well as in and two exhibitions in the National Archives / City Archive of Tallinn. Most of the sources addressed under the subtheme have been brought into scholarly circulation for the first time.
2.2.3. Major results
The major research results under subtheme can be summarised in the following:
- finding aids for the following archives has been developed: the archives of local communities in the XIX century; the archives of the Estonian Lutheran Church, and the archives of the Tartu City Council in the XVII-XX centuries. The developed finding aids cover about half of the data sources on historical population in Estonia [15; 19]
- the methodology for linking the population data from various ecclesiastical and civil sources for the XVIII and XIX centuries has been developed, and on that basis, family reconstitution for Kolga-Jaani parish has been accomplished
- source-critical analysis on the largest collection of individual census lists from the 1897 census preserved in Estonian Archives (totalling over 46 thousand lists) has been accomplished, providing a basis for analyses and monograph discussed under the previous subtheme [4]
- source-critical analysis of civil sources on population from the end of XIX century, including the comparison of the 1897 census lists and civil rolls on Jõgeva parish, the analysis of discrepancies between sources
- the methodology for assembling and linking the records based on the genealogical collections, parish registers, civil lists of the German-Baltic nobility has been developed, covering the period from XIII to the beginning of XX century [18]
- digital database and relevant procedures for storage, editing and computerised analysis of historical opulation records has been developed, using the SQL software standards
- computer applications for mapping and analysis of historical population data been developed, based on 2.5-dimensional GIS [4]
- the development of computer-assisted methods of family reconstitution, including approriate software applications, based on SQL standard; the development is in progress
