These are state total records for the 1990 School District Databook (SDDB). They are taken by the NBER from the SDDB files as provided by NARA with a slight change in format, and not recalculated from the lower level data provided in the same files.

More information is available at http://www.nber.org/sddb

There should be 51 records in each file, one for each state plus the District of Columbia. However, there are missing HT(1) records for California (state 6) and missing type CP(6) records for California (state 6), Ilinois (17), Minnesota (27) and New Jersey (34).

There are duplicate type CP(6) records for Michigan (26), Nebraska (31), New York (36), Ohio (39) and Pennsylvania (42).

I do not know if the duplicate records have similar data, or if one or more of them might be records missing from other states. It is known that a portion of the Minnesota file is defective. Please be cautious about using these files without detailed examination, and please inform me of anything of interest that you learn.
