DUI, Part 2: How many drivers are arrested for DUI in West Hollywood?
In our previous report, we looked at collisions caused by driving under the influence (DUI). Now we examine DUI arrests and the age and gender of DUI drivers. The number of arrests depends on both the underlying level of DUI and the level of enforcement activity.
DUI arrests in West Hollywood
The chart below shows the DUI arrest numbers for West Hollywood. You can see the number for a particular year by hovering over or touching the data point. The chart also includes the number of DUI collisions for context.
The number of DUI arrests rose sharply in the last decade, peaking at 259 in 2011. It fell to 154 — three a week — in 2014. We don’t know if there were changes in the level of enforcement during this period.
Comparison based on licensed drivers
California’s Office of Traffic Safety (OTS) calculates a standard measure of DUI arrests as a percentage of the estimated number of residents licensed to drive. We have re-expressed the OTS numbers as arrests per 1,000 licensed residents in the chart below.
In 2014, West Hollywood was at the top among nearby cities with 7 DUI arrests per 1,000 licensed residents. That was still below the state average of 8 per 1,000 licensed residents. This measure doesn’t adjust for workers, visitors, or pass-through drivers or for differences in enforcement.
Comparison based on vehicle miles traveled
We have another measure that isn’t limited to residents: DUI arrests per 100 million vehicle miles traveled (VMT). VMT is the sum of all the miles all vehicles traveled on the city’s streets in a year, not just residents’ vehicles. We rely on VMT estimates from the California Department of Transportation.
Based on this metric, West Hollywood came in second among nearby cities with 79 arrests per 100 million VMT. That put the city between Burbank (93) and Santa Monica (60). The numbers could reflect more underlying DUI, or greater enforcement activities, or both.
The chart below shows the age distribution of those arrested for DUI in West Hollywood. Arrests are concentrated in the 20s and early 30s. West Hollywood and Beverly Hills share a somewhat younger DUI profile than the other nearby cities.
Almost 70% of those arrested for DUI in West Hollywood are men. The percentage is similar in Beverly Hills, Santa Monica, and Culver City. It is higher — around 80% — in Burbank and Los Angeles.
