The 1870 census commenced on June 1, 1870, and was taken under the provisions
of the census act of May 23, 1850. 12
The Secretary of Interior appointed General Francis A. Walker Superintendent of
the Ninth Census on February 7, 1870.13 Although the 1870 Census was under the
1850 act, a new bill approved on May 6, 1870, made the following changes:
- The marshals were to submit the returns from "schedule 1" (free
inhabitants) to the Census Office by September 10, 1870. All other schedules
were to be submitted by October 1, 1870.
- The 1850 law authorizing penalties for refusing to reply to the inquiries
was expanded to apply to all inquiries made by enumerators.
Redesigned schedules used for 1870 and the omission of a "slave" schedule
made possible several additional inquiries as follows:
- General Population Schedule. This schedule collected data from the
entire population of the United States.
- Mortality. This schedule collected data on persons who died during
the year. In addition to the 1860 inquiries, inquiries were modified to
include Schedule 1’s additions to collect data on parentage and to
differentiate between Chinese and American Indians. Inquiries concerning "free
or slave" status and "number of days ill" were discontinued.
- Agriculture. The 1860 inquiries were used with additional requests
for (1) acreage of woodland, (2) production of Spring and Winter wheat, (3)
livestock sold for slaughter, (4) total tons of hemp produced, (5) total wages
paid, (6) gallons of milk sold, (7) value of forest products, and (8)
estimated value of all farm productions.
- Products of Industry. Using the 1860 schedule as a basis,
additional information was requested on (1) motive power and machinery, (2)12
Although a Congressional committee stated that the 1860 Census had been "the
most complete census that any Nation has ever had," it was recognized that the
1850 act was inadequate to meet the changing conditions in which the 1870
Census would need to be conducted. A special committee of the U.S. House of
Representatives (Second Session, Forty-First Congress) investigated and
reported on the need for a new census act. The committee’s report was
submitted as a bill on January 18, 1870. This bill was passed by the U.S.
House of Representatives, but defeated in the Senate, compelling the use of
the 1850 Census act. 13 General Walker was one of several "experts"
participating in the U.S. House of Representatives’ Committee deliberations on
the 1870 Census. Prior to being appointed Superintendent of the Ninth Census,
Walker was Chief of the Bureau of Statistics, which then was an agency within
the Treasury Department.
- Social Statistics. The 1860 schedule was modified to incorporate
the questions on (1) bonded and other debt of counties, cities, towns, and
townships, parishes, and boroughs, (2) pauperism and crime by race ("native
black" and "native white"); (3) number of church organizations and church
buildings; (4) number of teachers and students; (5) kinds of schools,
libraries, and taxes, by type.
The 1870 enumeration was completed on August 23, 1871. The work of compiling
the census data, a portion of which was tallied using a machine invented by
Charles W. Seaton, was completed in 1872.

Genealogy Strategy for the 1870 Census
Due to it's early nature the 1870 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.
- 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
1870 census will provide you the district, township, and county of your
- Establishing the Composition of a Family
Individual names are provided. No relationships were given in the
census, instructions were provided to the census taker as to which order to
enumerate a household. "The names are to be written, beginning with the father
and mother; or if either, or both, be dead, begin with some other ostensible
head of the family; to be followed, as far as practicable, with the name of
the oldest child residing at home, then the next oldest, and so on to the
youngest, then the other inmates, lodgers and borders, laborers, domestics,
- Age of Inhabitants
The 1870 census (column 13) indicates the month in which the person
was born, if born "within the year," that is between June 1, 1869 and May 31,
1870. While not an exact age, the fact that you're provided the year each
person is born will assist you in finding birth records.
- African American Research
After the Civil War, slaves were "freed" throughout the South. Researching
your African American ancestry after since 1870 is much easier through use of
the census. There were a total of 4,835,562 coloreds enumerated in the 1870
census of the United States3.
- Tracking the Migration
The 1870 census provides the birthplace of each individual. Along with
the age of each individual this can enable the genealogist to track the
location of the family at different years in the past. The instructions
provided to the enumerators requested that they provide the initials or name
of the state, or country of each person enumerated. Some enumerators would
provide an even further breakdown, such as county or township, especially when
the birth occurred in the state of the enumeration.
The occupation of each male family member over 15 is recorded. Indication of a
farmer would point to further searching of Schedule 4, agricultural census. A
mention of a profession would indicate possible search of a professional
directory. Clergy were enumerated as well under occupation, and the
genealogist should search within the records of the denomination indicated.
- Real Estate
An indication of real estate value might point to land or tax records.
- Personal Estate
The personal value of an individuals estate is likely to err on the side of
less, rather then more. It is highly likely that the person being enumerated
was unlikely to provide a true net worth as they were afraid of being taxed on
the amount given.
- At School
An indication of being at school within a household might point to
local school records.
An indication of insane within a household might point to
guardianship or institutional records.1
The indication of a persons enumeration as a convict is rare,
unless the census actually finds them in the jail at the time of the census.
Furthermore, a person in jail, may be listed twice, if his home was in a
different district. Instructions given to the enumerator was to ask, or use
their own knowledge and county records as a source, in identifying those who
had been a "criminal" within the past year.
- Native American Research
The identity of an Indian in the 1870 census is helped by the
identification of Indians as (I) in column 6.
- Children of Immigrants
The 1870 census is the first to identify those children of foreign
born parents (columns 11 + 12). Researchers can use this information to look
for further immigration records.
Individuals of foreign birth who are eligible to vote, also
indicates citizenship, and researchers should look to naturalization and court
records for possible further leads.
