How to Use xSub

xSub /cross-sub.org/ is a repository of micro-level, subnational event data on armed conflict and political violence around the world.

Through the online interface, users may select:

  1. a country and data source, in either order.

  2. a unit of analysis

    • space: country / province / district / grid / electoral constituency

    • time: year / month / week

The website then generates a compressed archive with:

  1. dataset

    • file format: comma-separated values delimited text file (.csv)

    • data structure: cross-sectional time-series

    • number of observations: N × T, where N is the number of spatial units (e.g. districts, grid cells), and T is the number of time units (e.g. months, weeks)

    • variables included: unit IDs, violence event counts (broken down by actors and tactics), covariates (local demographics, geography, ethnicity, weather)

  2. map and time plot of violence

    • file format: portable network graphics (.png)

    • map: number of violent events per spatial units (darker shade = more violence)

    • time plot: number of violent events per time unit (higher bars = more violence)

  3. codebook

    • file format: portable document format (.pdf)

    • contents: information on variable names, data structure

  4. actor dictionary

    • file format: portable document format (.pdf)

    • contents: information on which specific actors are classified as “government,” “rebel,” and other categories in the file
