xSub /cross-sub.org/ is a repository of micro-level, subnational event data on armed conflict and political violence around the world. Our goal is to preserve and consolidate multiple open-source data collections in one comprehensive electronic archive, creating a “database of databases” for purposes of research, education, policy-making and evaluation. The archive currently includes data on violence and protests from 139 countries (1942-2016), from 21 data sources, including both large data collections and individual scholars. To facilitate comparisons across countries and sources, xSub organizes these data into common units of analysis, by space (country, province, district, grid cell, electoral constituency) and time (year, month, week). The data are available to download, at no cost, from the data page or through the xSub R package. For more information, please see our introductory article and appendix.
xSub is grateful for support received from the Center for Political Studies at the Institute for Social Research, and the Department of Political Science at the University of Michigan, and to our many contributors and partners.
