United States Census Indexes

United States &gt;  U.S. Census  &gt;  Indexes

Index Accuracy
The information in an index may be incomplete or incorrect. If you have reason to believe your ancestor should have been in the census, search the census regardless of the information in the index. In large cities, learn the person's address by searching the city directory. for the same year as the census (see the “Directories” section of this outline). Then look for that address on the original census schedules starting in 1880. Prior to 1880 it may be helpful to learn the ward where a person resided.
