Database: Nations, Development and Democracy: 1800-2005 (Wejnert 2007) → link

For research purposes, I compiled three categories of data on political, social and economic variables related to democratization into a database Nations, Development and Democracy: 1800-2005 (Wejnert 2007) deposited with the Inter-University Consortium for Political and Social Research The database is web interactive.

The database was constructed by merging variables derived from existing datasets (Wejnert 2007). The database assesses 187 sovereign countries (20 historical and 167 contemporary), from 1800–2005, on indicators that represent the level of democracy, socioeconomic characteristics, and diffusion processes. Nineteen countries for which substantial data on indicators of socioeconomic development and/or of diffusion were missing were incorporated into the database but dropped from analyses on democracy and world development, yielding 168 sovereign countries in conducted studies on democracy. Following Gurr, Jagger, and Moore (1990), "sovereign country" was defined as an independent member of the international system that had a population greater than 500,000.

The database was constructed for its application in variety of statistical research including advanced statistics of Hierarchical Linear Models. Within the last 3 years alone (from 11.30. 2011 to 11.30.2014), the database was used and downloaded by 1710 scholars at 170 institutions, including Princeton University, Yale University, Harvard University, Stanford University, Columbia University, Cornell University, Duke University, Georgetown University and University of Michigan
