This week, I am sharing a couple of maps that show the place of residence for people working at the current NGA location in south St. Louis City. The idea to create these maps came from a recent blog post I read on the website Urban Review Saint Louis. The blog post is titled “New NGA West Location Will Gut St. Louis Place Neighborhood, Not Revitalize What Remains.” The blog briefly remarks on the potential impact of the new NGA location on its surrounding community and includes the following quote:

Once open, the NGA will be like the current site. Thousands will drive there, do their job, drive home…An employee living in, say Arnold, isn’t suddenly going to move to the neighborhood.

After reading this quote, I was curious about the place of residence for jobs near the current NGA location. To create these maps, I used data from the Longitudinal Employer-Household Dynamics (LEHD) dataset. I discussed the LEHD dataset in a previous post, which you can read again here.  The first map shows my area of interest. The red area is the site of the current NGA, and the light green area is the Census Block Group that surrounds it.

Next, I mapped the place of residence for people working in my area of interest. This map is shown below. This basic map shows relatively larger numbers of people living south of St. Louis City and County near I-55 and I-270.  This area includes Arnold and Oakville. In Illinois, there are large numbers of people living in Columbia and near Belleville.

This map is informative, but it does not account for the size of each tract. For example, the tract near Arnold looks as though it is as big as multiple tracts in St. Louis City.

In the next two maps, I account for tract size by dividing the number of jobs by the tract’s area. In other words, these maps shows place of residence density. Here, we can see relatively high place of residence densities in pockets of Oakville and Arnold, but density seems to be higher in several neighborhoods of St. Louis City. These maps show high place of residence density in the communities between Tower Grove Park and the current NGA site, as well as other pockets of south St. Louis City. The map below highlights all the tracts that are in the top tier of place of residence density. This map shows high density in Tower Grove East, parts of Dutchtown, the Central West End, the West End neighborhood, and a part of University City.

While these maps do not offer any conclusions about how invested employees of the NGA are in the surrounding community, they do show that a large portion of NGA employees live relatively close its the current location.
