I earlier produced maps showing how SacRT routes related to population density and income (SacRT with income and population). I also wanted to present a map on employment or jobs – where people are going to on the transit system. It took much longer to track down that data, and I needed help from SACOG’s GIS staff. The employment data is from the Census Bureau’s Longitudinal Employment-Household Dynamics (LEHD). The data is normalized over area. The map is below, with the SacRT_employment pdf also available.

So, what does it show? Well, employment is concentrated in a very few areas of the county, far more concentrated than income levels or population density. The only green areas on the map are in downtown Sacramento, with a few other less important centers. The existing transit network also focuses on downtown. It is worth remembering that only a portion of trips on transit (or in motor vehicle) are commuting to work, but it is one of the important functions of a transit system is to connect people to jobs. Of course a more economically robust region would have more people living closer to jobs, but given the population distribution of the moment, SacRT does a good job of this connection.

I am thinking about some method of showing population (the source) and employment (the destination) on the same map. If I figure that out, you’ll see it here.
