In this week’s edition of the Community Builders Exchange, we are looking at the age of buildings in the St. Louis region.  The first two maps show the median age of buildings by census tract throughout the region. It is not surprising to see that much of the region’s older buildings are in St. Louis City and the inner ring suburbs of St. Louis County. However, not all buildings in the city are all that old. We can see several tracts in the central corridor with a median age comparable to that of west St. Louis County. One tract in particular has a median building age after 2000.

The last two maps zoom into the central corridor. The first map shows the central corridor with an overlay of landmarks (designated by the US Census). Several of the “younger” census tracts are north of and adjacent to St. Louis University’s campus.

The final map adds an overlay of bar charts showing the number of structures built by decade after 1970. In Downtown St. Louis, for example,  this map shows there were more structures built in the 1970’s and 1980’s than in more recent years. In the green tract north of SLU’s campus, few structures were built in the 1980’s and 1990’s, but there appears to have been a building spree in the last decade.

The four maps below were made using data from the 2014 American Community Survey. To see maps from previous editions of the Community Builders Exchange, click here.
