Understanding LEHD and Synthetic Home to Work Flows in "ON THE MAP"

Where do the Data Come From? Text version

The data used in "On the Map" come from two sources. Home Block Data and Workplace Block Data.

The second data source is called Workplace Block data and is related to where the workers work. The Workplace Block data come from the Quarterly Census of Employment and Wages or ES-202 information provided by each state which is compiled from reports filed by employers each quarter.
