As in the earlier censuses, the 1840 census still lists only the head of household by name. The rest of the family members are still broken down by age groups but the groups are broken down further, giving the researcher a much clearer picture of family members. The new category for deaf, dumb and blind persons can be a lead to research in institutions, schools and hospitals for records.
This census included a separate listing for all Revolutionary War pensioners, thus creating what you will often find online listed as the 1840 pensioners census.
For the 1840 census, the age categories were expanded again. Additionally, some social categories made their first appearance. Each head of family was listed and was asked:
