The Census Bureau releases several series of printed reports that are grouped under three broad titles: 1990 Census of Population and Housing (CPH), 1990 Census of Population (CP), and 1990 Census of Housing (CH). The following publication series contain data for AIANAs:
| CPH-1 | Summary Population and Housing Characteristics |
| CPH-4 | Population and Housing Characteristics for Congressional Districts of the 103rd Congress |
| CPH-5 | Summary Social, Economic, and Housing Characteristics |
| CP-1 | General Population Characteristics |
| CP-1A | General Population Characteristics for American Indian and Alaska Native Areas |
| CP-2 | Social and Economic Characteristics |
| CP-2-1A | Social and Economic Characteristics for American Indian and Alaska Native Areas |
| CP-3 | Population Subject Reports |
| CH-1 | General Housing Characteristics |
| CH-1-1A | General Housing Characteristics for American Indian and Alaska Native Areas |
| CH-2 | Detailed Housing Characteristics |
| CP-2-1A | Detailed Housing Characteristics for American Indian and Alaska Native Areas |
Data items, geographic coverage, and presentation format vary with each report series. For instance, the CPH-1 series, Summary Population and Housing Characteristics, contains 100-percent data issued in a U.S. Summary report, and individual reports for each State and statistically equivalent entity. Reports contain several important items of data for the AIANA populations. Tables 17 and 18 of the individual reports provide selected population and housing characteristics for AIANAs within the State, as well as land area for each reservation and trust land in square kilometers
