Dear Mr. Muir:

I am responding to your inquiry about the availability of data
from the 1970 and 1980 Census of Population and Housing for
ethnicity reported by congressional district.

The Center for Electronic Records has in its custody a number of
data files from the 1970 Census.  Congressional District summary
data is reported in the First Count File 1B.  'Ethnicity,' as
defined in the 'Index to 1970 Census Summary Tapes,' is reported
by the variables 'Country of Origin,' 'Mother Tongue,' 'Nativity
and Parentage,' and 'Race.'  With the exception of the variable
'Race,' all the other ethnicity related variables are in the
fourth or fifth count files.  Therefore, the closest tabulation
by congressional district would be in the First Count File 1B.
Below is information about the First Count File 1B data files in
the custody of the Center for Electronic Records.

I hope this information is useful.  If you have any questions,
please contact me at the Center for Electronic Records (NSX),
ATTN: Reference Staff, National Archives, Washington, DC 20408.
The telephone number is (202) 501-5579.  I can also be reached
via Internet at tif@cu.nih.gov or BITNET at TIF@NIHCU.

Sincerely,



THEODORE J. HULL
