A closer look at transit ridership around LA County

The proportion of commuters who use mass transit to get to work varies wildly across the Los Angeles Metropolitan Statistical Area (which encompasses Los Angeles and Orange Counties). Source: 2000 U.S. Census.

Last week, The Source mentioned an Australian study that concluded that perhaps the connection between higher density and transit use was not as robust as previously thought. The study authors also suggested that Los Angeles was a prime example of their theory: a dense city with “relatively low rail and bus use.” I think that suggestion merits a closer look.


For starters, what’s relative? Across Los Angeles County, 7.3 percent of people over the age of 16 ride mass transit to commute to work. That is certainly below many older cities and counties with more miles of fixed rail than Los Angeles. These cities include Washington D.C., Boston, Chicago, Philadelphia and New York — where in the New York-White Plains metro area 44 percent of commuters use mass transit. But the percentage in L.A. County is still above the national average of five percent who use transit to get to work. And it’s similar to the percentages in some metro areas that are about the same size as massive L.A. County.

Secondly, as the following map illustrates, the proportion of residents who ride mass transit to work varies wildly across the Los Angeles Metropolitan Statistical Area, as defined by the Census Bureau. Noticeably, the densest parts of L.A. also contain high proportions of transit commuters. Here are some examples from randomly chosen Census Block groups around L.A.: UCLA, 41%; Hollywood, 39%; Downtown, 59%; Koreatown, 64%; MacArthur Park, 67%; the area southeast of the 10 and 110, 85%.

And take a closer look at the maps below: you’ll see there are many pockets outside L.A.’s densest areas which contain high concentrations of transit ridership; These areas include the Van Nuys Boulevard corridor in the San Fernando Valley and parts of Santa Ana, Anaheim and Garden Grove in Orange County.

Perhaps density is not the best way to predict how many people ride transit, as the Australian study concludes. But the suggestion that L.A. is a dense city with poor transit ridership is an oversimplification and downplays the complexity of transit riding habits and patterns in our city and region.
