Source. ACLED Trends platform — organized violence (battles, explosions/remote violence, and violence against civilians; excludes protests, riots and other demonstrations), counted by country.
Measured, not forecast. Each period is a 4-week window of observed (coded) events. Figures for recent periods may be revised as coding continues; the latest_update column is ACLED's most recent data refresh.
Rolling windows — don't sum across periods. The 4-week window advances about one week per report, so consecutive periods overlap by up to 3 weeks. Treat each period_end as its own snapshot; adding event_count across periods would double-count shared events.
Change columns. change_pct and change_abs compare the period against the average of the comparison baseline (Year = average of the prior 12 months). change_pct is a fraction: 0.16 = +16%.
Coverage. All countries and territories are included, including those with zero events.
Updates. Scraped daily; ACLED typically publishes a new report mid-week. The cumulative all file is one row per country per measured period.
