We published a report in 1992 on Commuting Patterns in the metropolitan Washington region that included tables on 1980 and 1990 county-to-county worker flows for jurisdictions in the metropolitan region. The report is not available in electronic form, but I could arrange to get you a hard copy of it if that would help.

Does anyone know if this historical data (I'm interested in 1970 and
1980) is tabulated according to the place of work?  That is, I want to
find out where all workers in a given jurisdiction are commuting from.
I'd even be satisfied to know the percentage of workers that are coming
from outside of a given jurisdiction.

The data available at the link below is fantastic, but as far as I can
tell, it is only available according to place of residence.

Thank you for any help you can give me.

Bob and others:

The 1970, 1980 and 1990 data on county-to-county total commuter flows is
available on the Department of Commerce, Bureau of Economic Analysis web
site at:

Anything finer grained that county, or county-to-county by means of
transportation to work, would have to be extracted from your old 1970
UTP, 1980 UTPP and 1990 CTPP data files.

Note that the 1980 Census workplace information was coded for only half
of the long form sample. So, essentially the sampling rate for the 1980
commute flows is about 1-in-12, not the 1-in-6 sampling rate we have
from the 1990 and 2000 Censuses.

Also note that the largest county-of-work in the 1970 Census is "Not
Reported."  So, take care in how you report/allocate/impute the 1970
data, if at all.

Pardon my asking this, but are county-to-county worker flows available
from the 1980 census datafiles?  I know that it goes back a bit and is
not the latest and greatest from the US Census.  I have some flow data
but am looking for additional counties to include in my review.
