Aggregate counts of reported Queensland road crashes from 1 January 2001 by contributing factor. Each row is one combination of year, police region, crash severity and four yes or no factor flags. The publisher can only supply full contributing factors for finalised crashes, so the most recent months are lower than they will be.

Part of Crash data from Queensland roads, 6 tables the publisher releases together: Road crash locations, Queensland, Road casualties, Queensland, Driver demographics in road crashes, Queensland, Seatbelt and helmet use in road crash casualties, Queensland, Vehicle types in road crashes, Queensland.

Format
"Latest" redirects to the newest version and will change when the publisher releases again. A dated version never changes.

What this site did to the data. Cells were typed, headers were renamed and the encoding was made UTF-8. Rows were left alone. The publisher's file sits beside every version as source.csv so the change can be checked.

The publisher releases Crash data from Queensland roads as 6 files at once, so all 6 tables here share a version date.
