Journey to work

Journey to Work is the number of commuters from a county of residence to a county of work, for 1970, 1980, 1990, and 2000. The Journey to Work data are derived from the decennial census of population, which has included a journey-to-work question on the Census long form since 1960. The data for all years reflect editing by BEA (primarily, assigning unusually long-distance "commuting" flows to the "place- of-work elsewhere" category). Every effort has been made to make the 1960-2000 observations internally consistent over time and across geography with minimal alteration to the original JTW tabulations as received from Census.

The Census JTW tabulations were derived from the decennial Census questionnaire, which asked sample households to report detailed characteristics of their employment (such as location, means of travel, and income earned). Since 1960, processing of the JTW related questions from the decennial census has been funded through the U.S. Dept. of Transportation. Commuters' earnings information did not appear on the JTW tabulations until 1970, and a detailed breakdown by industry was not available until 1980.

The Journey to Work dataset is online at BEA and at the Census Bureau.
