1880 Census and More

In 1880, the decennial federal census was recorded. This was the first census that provided the relation of every member of the household to the head.

Did you know that additional information was recorded on people who had special needs and/or lived in institutions because of these needs? The database at Ancestry is titled U.S., 1880 Federal Census Schedules of Defective, Dependent, and Delinquent Classes. Let's use the term "supplement to the census."

I just discovered this and thought I'd share my findings.

Please note that the terms used for these people and institutions were standard for the year 1880. Most have fallen out of use today and seem archaic or degrading.

Searching the 1880 census will not give results in the supplement to the census. These are separate databases at Ancestry. A potential match might appear in the "Suggested Records" column if you click on an entry in one database.

How would you know to look for someone on the supplement to the census? Either because they are enumerated as an occupant of an institution or because they answered in the affirmative to the questions about health.

1880 federal census questions about health

Question 15: Is the person [on the day of the Enumerator's visit] sick or temporarily disabled, so as to be unable to attend to ordinary business or duties? If so, what is the sickness or disability?

Question 16: Blind,

Question 17: Deaf and Dumb,

Question 18: Idiotic,

Question 19: Insane,

Question 20: Maimed, Crippled, Bedridden, or otherwise disabled.

Words or a slash mark in these columns merit a visit to the supplement to the census. Additional information was collected about the nature and length of the condition. This may or may not be accurate.

Specific to Newark, Essex County, New Jersey were several institutions, triggering the residents to appear on both the 1880 federal census and the supplement:
-Newark City Alms House on Elizabeth Avenue. Date of admission is on the supplement.
-Home for the Friendless on South Orange Avenue. Date of admission and number of brothers and sisters is on the supplement.
-Essex County Asylum for the Insane on Camden Street. Supplement includes illness, length of current attack, number of attacks, and age at first attack.
-Protestant Foster House on Belleville Avenue. Supplement includes date of admission and circumstances of birth.

Information, including spelling and indexing, can vary from the census to the supplement. The correct person can be confirmed because the enumeration district, page number, and line number of the census are included in the supplement.

Mary Staats (1840-1892) has possibly four entries in the 1880 census and supplement.

476 Mulberry Street, Newark, New Jersey

In the 1880 federal census, Mary was enumerated at 476 Mulberry Street in Newark with her husband, Abraham, their two children, and a servant. [Indexed as Stadts at Ancestry.] For the question about occupation, "keep house" is scratched out and "insane asylum" written above. The box for "insane" is ticked.

Enumeration District 65.

Mary is listed in the supplement. We know this is Mary because of the enumeration district, 65, in the upper left corner. Next to Mary's name is the page number, 15, and line number, 43. [Indexed as Staats at Ancestry.] Additional information is that Mary suffers from mania, which struck for the first time one year ago when she was 39 years old. Also, she is currently housed at Newark Asylum.

So I checked for her in the 1880 census in the Asylum, Enumeration District 68.

In the 1880 census, there is a woman named Mary Staats listed at the Insane Asylum. [Indexed Stoats at Ancestry.] But her age was given as 68 years, birthplace New York.

The supplement provides a few more details. Still 68 years old, married but also widowed. Suffering from her first bout of mania for four months.

The information provided about Mary in her home is probably more accurate and reliable because a family member spoke with the enumerator. At the institution, the enumerator did not speak to every inhabitant because of efficiency and because most occupants may have been too incapacitated to relay accurate information. The informant at the institution would not have personally known the accuracy of any specifics.



The takeaway is to look for additional information in the supplement if someone answered yes to a health question in the 1880 census, or if they resided as a pauper, orphan, or mentally or physically impaired person in an institution.
