xSub: Cross-National Data of Sub-National Violence

xSub is a repository of micro-level, subnational event data on armed conflict and contention 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 armed conflict and contention from 195 countries (1968-2019), from 22 event data sources, including both large data collections and individual scholars. The data are available as individual events, and as analysis-ready spatial panel datasets. 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, day). We also provide several pooled, multi-source versions of the data for every country.
