Change in transit commuting for areas around some LA Metro stations, 2000 to 2005-2009

I was interested in finding change in transit ridership between 2000 and the 2005 to 2009 period captured in the American Community Survey, so I mapped the ACS2009 5-Year data and Census 2000 data at the block group level, then joined it with station areas, using area-weighted allocation for any block groups only partially within a 1/2 mile radius area.

We have a lot of data that is currently being used in research projects, but I wanted to share some of the findings below.

Which station areas experienced the highest growth in total number of transit commuters?

RED/PURPLE - WESTLAKE / MACARTHUR PARK2530.5
RED/PURPLE - WILSHIRE / VERMONT1784.8
PURPLE - WILSHIRE / NORMANDIE1711.1
RED - VERMONT / SANTA MONICA1172.4
RED - VERMONT / SUNSET743.3
RED - HOLLYWOOD / WESTERN610.5
RED - VERMONT / BEVERLY601.1
BLUE - ANAHEIM461.4
ORANGE - RESEDA STATION431.4
ORANGE - VAN NUYS STATION297.6

Which station areas experienced the greatest change in the percentage of workers who commuted on transit?
GREEN - I-105 / AVIATION8.24%
BLUE - WILLOW6.19%
GOLD - S WEST MUSEUM / FIGUEROA5.95%
GOLD - ALLEN AVE5.62%
RED - VERMONT / SUNSET4.23%
ORANGE - DE SOTO STATION4.12%
GREEN - I-105 / AVALON4.09%
GOLD - MISSION ST4.05%
GREEN - NASH / MARIPOSA3.92%
GOLD - HOLLY ST3.57%

Many of the green line stations in the second table have very few workers in the area, so the numbers are skewed. For instance, the I-105/Aviation station only had 800 workers within 1/2 mile, and 40 of them took transit.

Obviously the new Gold and Orange lines would be expected to create new transit commuters, since they opened in between the two Census surveys.  I think the big success story is the Vermont and Sunset station, which added 743 transit commuters and 2,023 workers between 2000 and 2005-2009.  This likely indicates that many people moved to the Vermont/Sunset station area specifically because they wanted to take transit to work.

What do you think?
