Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
HISPAN identifies and classifies persons of Hispanic origin in the United States and Puerto Rico.
Comparability — Index
Comparability — General
The first digit of HISPAN retains only distinctions common to all years; the second and third digits distinguish additional groups and subgroups. The number of groups identified varies between samples.
For each census, the variable is derived from a question designed specifically to identify Hispanics and classify them according to their background. The question was worded somewhat differently across censuses.
Comparability — Puerto Rico [top]
This variable is available only in the 2000-2010 samples. It is fully comparable across these samples.
Comparability — United States [top]
The 1980 sample has the least detailed subcategories and 1990 has the most. The 1990 sample reports detailed codes for persons of Mexican origin.
