County-To-County Worker Flow Files

These files were compiled from Census 2000 responses to the long-form (sample) questions on where people worked. The files provide data at the county level for residents of the 50 states and the District of Columbia (DC). Similar files containing data for county subdivisions (MCDs) in 12 states and counties in the other 38 states, DC, and Puerto Rico are available at http://www.census.gov/population/www/cen2000/commuting/mcdworkerflow.html. The main journey to work and place of work subject matter page may be found at http://www.census.gov/population/www/socdemo/journey.html.

For any State, or for the entire nation, there are a number of files to choose from, depending on the sort order and format you may find most useful.

The sort order refers to whether the county of residence or the county of work is the main focus. If you are interested in the number of people who live in a county, and want to know where they work, you should download one of the files sorted by county of residence. These files will show you all the work destinations for people who live in each county.

On the other hand, if you are interested in the people who work in a county, and want to know where they come from, download one of the files sorted by county of work. These files will show you all the origins for people who work in each county.

The files have been created in two formats: plain text and Excel spreadsheet format. The Excel files and the uncompressed plain text files are directly viewable. To look at the data on your screen, click on the underlined link "Excel" or "Uncompressed" for the format, state, and sort order you want. To download an Excel or uncompressed plain text file, hold down the shift key and click on the underlined link.

The compressed plain text files are not viewable; they have been zipped for faster downloading. To download one of the files simply click on the underlined link "Compressed" for the state and sort order you want. For information on using PKZIP/PKUNZIP see our PKZIP information page.

The documentation for the files is available below. To view the file, just click on the underlined link "record layout" and the file will be displayed on the screen. You can then print the page from your browser. To download the record layout, hold down the shift key and click on the underlined link.

Note: In reviewing the Census 2000 County-to-County 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 (SF3) and related products. 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.
