Dear SOS-DATA and Ms. Woo:

I am responding to Jim Cassell's post to SOS-DATA on behalf of Ms. Woo
regarding County to County flow data.  While we are not specifically
working with these data, we have recently received a transfer of a
number of these files in the Records of the Internal Revenue Service
(Record Group 58).

These data are the County to County, State to State and County Income
Migration Flow Data, 1978-1980, 1980-1981, 1983-1984, 1984-1985,
1985-1986, 1986-1987, 1987-1988, 1988-1989, 1989-1990, 1990-1991,
and 1991-1992.  These data show inflows and outflows for each county
on number of taxpayers and personal exemptions.  Documentation
consists of 11 pages and is identical for all years available.  If anyone is
interested in further information about the content of these records or
their current availability, please contact me directly.

Finally, we have recently updated our Reference Report #3 with
descriptions of the Statistics of Income (SOI) data in our custody in the
Records of the Internal Revenue Service (Record Group 58).  The report
is available either in printed form or on the National Archives
Gopher/WWW server CLIO (gopher.nara.gov or http://www.nara.gov;
path: INFORMATION ABOUT NARA HOLDINGS/ INFORMATION ABOUT
RECORDS IN WASHINGTON DC AREA REPOSITORIES/ ELECTRONIC
RECORDS/ REFERENCE REPORTS AND DESCRIPTIVE HANDOUTS).  The
Center for Electronic Records has data files from the following SOI
series: A) the Corporate Source Book, B) Exempt Organization Study
Files, C) the Individual Tax Model File, D) Partnership Source Book, E)
Private Foundation Study Files, F) Sole Proprietorship Source Book, G)
the State Tax Model, and H) Migration Flow Data.

I hope this information is useful.
