GeoDist is a comprehensive database developed by CEPII (Centre for International Policy and Public Affairs) that provides a wide range of gravity variables for analyzing market access difficulties in global and regional trade flows. The database, accessible online at http://www.cepii.fr/anglaisgraph/bdd/distances.htm, includes country-specific and bilateral files that are useful for empirical economic research, particularly in estimating gravity equations that describe bilateral trade patterns. The country-specific files (geo_cepii.xls and geo_cepii.dta) cover 225 countries and include variables such as geographical coordinates, languages spoken, landlocked status, and colonial links. The bilateral files (dist_cepii.xls and dist_cepii.dta) provide various measures of bilateral distances (in kilometers) and other gravity variables like contiguity, common languages, and colonial ties. The main contribution of GeoDist is the consistent computation of both internal (intra-national) and international bilateral distances, using city-level data to assess the geographic distribution of population within each nation. This approach ensures that the internal distance ratio is accurately estimated, which is crucial for obtaining reliable estimates of trade impediments. The database also includes weighted distances, which consider the geographic distribution of economic activity, and simple distances, which use the most important city or capital. Additionally, the database provides dummy variables indicating specific relationships between countries, such as colonial ties and common languages. GeoDist aims to improve upon existing datasets in terms of geographical coverage, measurement quality, and the number of variables provided.GeoDist is a comprehensive database developed by CEPII (Centre for International Policy and Public Affairs) that provides a wide range of gravity variables for analyzing market access difficulties in global and regional trade flows.
