GeoDist provides several geographical variables, in particular bilateral distances measured using city-level data to account for the geographic distribution of population inside each nation. Different measures of bilateral distances are available for 225 countries. For most of them, different calculations of "intra-national distances'' are also available.
Methodology: a Short Description
The first dataset (geo_cepii), incorporates country-specific geographical variables for 225 countries in the world, including the geographical coordinates of their capital cities, the languages spoken in the country under different definitions, a variable indicating whether the country is landlocked, and their colonial links. The second dataset (dist_cepii) is dyadic, in the sense that it includes variables valid for pairs of countries. Distance is the most common example of such a variable, and the file includes different measures of bilateral distances (in kilometers) available for most country pairs across the world.
