Description
MSA or PMSA FIPS code - 1989-1997
Unicon Corporation made the following notes about this variable:
In June-August, 1995 hhid was being changed to the new format. The Census deliberately presented only a 5 digit ID in these months to make it impossible to identify individuals. Most geographic identifiers were also set to '-1' to insure confidentiality. Records in these 3 months cannot be matched to other months.
