Version V1

These files were compiled from Census 2000 responses to the long-form (sample) questions about where people worked. The files present data at the county level for residents of the 50 states and the District of Columbia. The residence file shows the number of people who live in a county and the work destinations for the people who live in each county. The work file shows the origins of the people who work in each county.

When the Bureau of the Census reviewed the worker flow files before release, some errors were discovered in a number of the county-to-county flows. These errors have been corrected. However, as a result of the corrections the data in these files may not agree with data previously released in Summary File 3. In particular, there may be differences in the number of people working in the state and/or county of residence between SF3 and similar estimates derived from these files.
