High Quality Transit Areas (HQTAs) are defined as being within 1/2-mile of fixed guideway transit and/ or bus rapid transit stations with service every 15 minutes or less during peak commute times. SCAG published two shapefiles of (HQTAs): one for actual HQTAs in 2012, and one for planned HQTAs in 2040. HQTAs were mapped for the county, along with population density.
2015 jobs data (selected as Work Area Profile Analysis in 2015 by all) was downloaded from the Longitudinal Employer-Household Dynamics Origin-Destination Employment Statistics (LODES) for LA County (most recent year available is 2015). LODES data exports a shapefile, using one point for each census block in which there is at least one job. Each point is then assigned a value equal to the number of jobs in the entire census block.
ArcGIS was used to determine the total number of 2015 jobs located in both 2012 HQTAs and planned 2040 HQTAs. For 2012 and 2040, the jobs shapefile was clipped by the HQTA shapefile, exported an excel file, and calculated the total number of jobs within an HQTA.
