These are counts of recorded accidents, not risk rates: the data has no flight hours, so a place or aircraft near the top mostly reflects how much flying happens there. Source: NTSB aviation accident database (US government, public domain), plus notable international accidents from Wikidata and Wikipedia. US-heavy; the NTSB only codes phase and cause for accidents from 2008 on, so those tables leave out earlier years.

StatisticsTrends and breakdowns for this selection
Phase and cause come from the NTSB’s own coding of each accident, which only exists from 2008 on, so these two filters leave out 1982–2007. Cause categories are only recorded for some accidents, and early findings can change.
