We use recent immigration data from 195 countries and propose an index of population diversity based on people's birthplaces. This new index is then decomposed into a size (share of foreign born) and a variety (diversity of immigrants) component and is available for 1990 and 2000 disaggregated...

This new index is decomposed into a "size" (share of foreign born) and a "variety" (diversity of immigrants) component and is...
