Harmonized data from the censuses (1989, 2000, and 2011) can be used in basic and applied research on a wide range of topics. The database covers, for example, the following topics:
- household and family structures of the population (independence of young people, transformation of family models, different generations);
- spatial location;
- internal migration;
- profiles and integration of migrants (by origin, migratory generation, and life expectancy, etc.);
- linguistic demography (stability and exchange of the mother tongue, acquisition of the Estonian language, knowledge of foreign languages);
- housing conditions and their changes.
By combining information on population events in the post-census years with census databases, it is also possible to create integrated databases for the personal analysis of population processes.
Users (researchers, public, and private users) can subscribe to a database based on readily available elements that are necessary to carry out the analytical task provided by the user and receive competent advice.
