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 armed conflict and protests 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.
We also welcome submissions of original data for potential inclusion in the xSub archive. For details, please see the data upload page.
The co-directors of the xSub project are:
