On 2 August 1790, shortly after the inauguration of President Washington, the
first enumeration commenced. Congress assigned the duties of the enumeration to
the marshals of US judicial districts. The law required that every household be
visited and that completed census schedules be posted in "two of the most
public places within [each jurisdiction], there to remain for the inspection of
all concerned . . ." and that "the aggregate amount of each
description of persons" for every district be transmitted to the President.
It is presumed that the Secretary of State (Thomas Jefferson), acting under
the authority of the President (George Washington), sent the marshals within
each state, copies of the census act, and the required inquiries. The marshals
then incorporated these inquiries into "schedules" of their own
design. Neither paper nor form was ever supplied to these marshals, and this
accounts for the differences in the copies of the available census. Each marshal
and/or their assistant was responsible for copying and posting the census in two
public places in their assigned areas. The hope was that those who viewed them
while they were posted, would check for accuracies or omissions.
The 1790 census covered the following states:
- New Hampshire
- New Jersey1
- New York
- North Carolina
- Rhode Island
- South Carolina
Schedules for some counties are missing.

Strategy for the 1790 Census
Due to it's early nature the 1790 census provides the littlest of
"meat" for the genealogist as it only names the head of the household
and provides a range of ages for all other occupants of the house . The content
of the census directly indicates the name of the head of household, and the
location of the family, but indirectly can be used to direct future research.
- Establishing the Composition of a Family
While it does not provide names, or exact ages, the 1790 census does
provide an idea of the composition of each family. In it you can find the
number of members of the family, their approximate age, and their sex. By
using other resources, such as vital records, wills, and land records you
can establish further details on each person in the household, and compile
further information like their exact name, birth, marriage and death
- Tracking the Head of Household
The 1790 census provides the name of the head of household. This will
be useful for tracking this family in future census.
- Location of the Household
As in all census, the location of the household at the time the
census was taken becomes a valuable tool for further research allowing you
to concentrate on records of that time period in that particular location.
The 1790 census will provide you the exact town or/and county of the
- Multiple Listings
It is possible, though highly unlikely, that your ancestor may
have been listed twice. Though most marshals had submitted their census on
time, there were a few late, which cause Congress to extend the deadline of
submission until 1792.
- Slave Research
Slaves were identified by the number of such in a household.
There were a total of 694,207 slaves enumerated in the 1790 census of the
United States3. Researchers who have identified
a slave holder of a possible ancestor should then consult probate or tax
records for possible further identity of specific individuals.
- Native American Research
It is possible to find your Native American ancestor in the 1790
census only if they were residing in an area being taxed.
