Event date precision

Global event-level living dataset of reported political violence, demonstrations (including protests and riots), and selected strategic developments. Available through an authenticated API in JSON, CSV, and XML and through account-gated export/download surfaces, with arbitrary country, administrative-area, location, date, taxonomy, actor, and other filters. Event rows are revised as better information appears; row timestamp, response update metadata, and a coordinated deleted-event endpoint support refreshes, but ACLED no longer publishes formal dataset versions after Version 8. This Source excludes CAST forecasts, Trends risk intelligence, alerts, Explorer summaries, and other modeled products. It is not a verified property-loss record: property effects are explicit only where the taxonomy or notes report them.

Event-level downloadable data file covering more than 200,000 domestic and transnational terrorist incidents worldwide from 1970 through 2020, with no incident file for 1993. The latest page citation is the 2022 release. Raw data are obtained after a brief active download form. Ordinary terms permit non-commercial research and analysis; commercial use requires an additional agreement. Collection stopped after partial 2021 work for lack of funding, so there is no promised current release cadence. START may correct records when new documentation appears and has no obligation to update.
