Information from the Census is tied to a State, County or Township boundaries and is dated to when the information was collected. Similarly, water quality, electricity consumption, and sociolinguistic accents are tied to geography and dated to when they were measured. Any attribute that is spatially explicit can be explored using Geographical Information Systems (GIS).
