1990 COUNTY-TO-COUNTY WORKER FLOW FILES

These files were compiled from STF-S-5, Census of Population 1990: Number of Workers by County of Residence by County of Work. For the six New England States (CT, ME, MA, NH, RI, VT), data are provided for Minor Civil Divisions (MCDs) instead of for counties.

For any State, or for the entire nation, there are four 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 most interested in the number of people who live in a county, and want to know where they go to 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 most interested in the people who work in a county, and want to know where they come from, you should 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 also been created in two formats: DBF and ASCII. The DBF files are directly accessible by a number of database, spreadsheet, and geographic information system programs. The ASCII files are more general purpose and may be imported into many software applications.

These files have not been designed to be viewed on the screen, but rather to be downloaded. However, you may view a file by clicking on "Uncompressed" for one of the ASCII files. The contents of the file will display on your screen, but you will have to scroll to the right to view the last field, the name of the county of work. (If you click on "Uncompressed" for one of the files in DBF format it will not display properly.) Clicking on "Compressed" for any of the files will begin the downloading process. NOTE: To download one of the uncompressed files you must hold down the shift key when you click on the word "Uncompressed."

The record layouts for the files are available below. To view either file, just click on the underlined text and the file will be displayed on the screen. You can then print the page from your browser. To download one of the record layouts, hold down the shift key and click on the underlined text for either the ASCII or DBF record layout. The link to the FIPS Lookup File can be used to access a list of FIPS State codes and the corresponding State names. In the county-to-county worker flow files, only the State codes are used. The files do not contain State names.

These files are also available in a compressed format for faster downloading. Don’t forget to download the file layout.
