Composition of Religious and Ethnic Groups (CREG) Data
To compliment the SPEED project and the study of conflict events, the Composition of Religious and Ethnic Groups Project (CREG) was started to create a set of time-varying measures that gauge the nature and depth of country-specific socio-cultural cleavages. It focused on 165 of the largest countries in the world (all countries with a population above 500,000 in 2004) during the post-WWII era to create country-specific projections on the relative sizes of the different groups during the postwar era.
