The City-Parish’s Geographic Information Systems division has upgraded its interactive maps of the parish with Census population data for every decade from 2010 dating back to 1890. GIS maps for the 2000 and 2010 Censuses have been merged with the recently added Historic Census page, making one convenient, interactive Census page. 

The East Baton Rouge Census maps show numbered tracts designated by the Census bureau; they are color-coded by population, with the deep-red end of the spectrum signifying the greatest numbers of residents. Prior to the 1960 Census, the parish was subdivided into wards. Users can toggle between years via a dropdown menu in the top right corner of the map, then click on a ward or tract to view its population count for that year. The 2000 and 2010 tracts include additional demographic information; click on a tract for a pop-up box, then click on the View link for detailed breakdowns of smaller subdivisions called Block Groups.

With the 2020 Census approaching, the Census viewer is another useful tool for people researching the population history of East Baton Rouge Parish.
