Statewide Integrated Traffic Records System (SWITRS)
2010 – 2020
The original data comes at the point level. Our team geocoded the locations to generate X/Y coordinates, then spatial joined each point to 2020 Census Tracts.
Why are these variables important to measure?
Although fatalities decreased 5% across the State of California between 2018 and 2019(CA OTS, 2022), more recent data has suggested an uptick in traffic collision-related deaths post-pandemic. Compared to Sunbelt metros, the nation’s major metro regions (i.e. LA, Bay Area, Chicago, and Washington) do fare safer on a per 100K capita basis. Nevertheless, highly populated cities bear a greater risk of collisions and tend to report at higher numbers.
