Employment Data

Employment data is notoriously difficult to obtain at a fine-grained spatial level.  The Census LEHD dataset has detailed employment data, by sector, at the Block level.  In many regions, that is the best source of detailed employment data.  Other sources are Traffic Analysis Zone (TAZ) data produced by entities running travel demand models, which is most often area MPOs, or in some cases cities or counties.  


A table below offers advice on how to convert the detailed, NAICS employment counts in the LEHD dataset to ET-friendly naming convention.
