1840 Census

Introduction

The 1840 census was the 6th Census of the United States. The data collected by the census takers was not comprehensive, but it is of great value to researchers. They obtained the name of each "Head of Household", and then a numerical enumeration of all of the other family members by age and sex.

Only the head of each household was listed by name, everyone else was only included by category. This means that you can't view the 1840 census and immediately know who everyone in each household was. However, you can use the data and compare it to data obtained from other records, and analyze the numbers and make educated assumptions about who was in the family. Of course, this is a hit and miss proposition with varying degrees of success.

For example, consider the household of a fictional "John Miller". He was listed with one male age 30-39, two males under 5, and 1 female 20-29, and 1 female under 5. From this we can assume that he was the male over age 30-39, and that the two males under 5 were his sons, and that the female 20-29 was his wife, and the younger one was his daughter. However, while this is often a safe assumption to make, it is quite possible that all three children were grandchildren instead, or orphaned nephews and nieces that they were raising. From this record alone, it can not be positively determined who was who in a 1840 census household. However, if you have a family bible record showing that John Miller had two sons, one born 1836, and another born 1839, then you can be reasonably sure they were the two boys with him in 1840. If the bible record also shows he had a daughter born 1837, then you can be fairly sure she is the younger female with him in 1840, and the other one is probably his wife. As you can see it takes some analysis to figure out how to interpret this record.

The 1840 census was taken state by state, and county by county, and in some cases the counties were further divided by districts (such as townships, companies, etc.). Some records were left in the original order the census taker visited each household, whereas others were alphabetized before being turned in. The ones in original order are very useful to determine who a persons neighbors were. If you see three Johnson families listed side by side, you can reasonably assume they are somehow related.

The Columns of Data

The 1840 Census was almost identical to the 1830 census, but it added several columns including the most important one (for genealogy anyway) of those who were Revolutionary War Pensioners. I will explain what each column represents in detail below.

The census was as of 1 Jun 1840, meaning all data collected (even if collected months after that date) was supposed to reflect the families condition on 1 Jun 1840, meaning all ages were to be listed how they were back on June 1st, even if it was three months later when the census taker asked. It isn't know if the census taker adhered to this rule or not, but that is what they were supposed to do.

The "page number" that I use on my published census abstracts are normally the stamped page number. Each "page" of the 1840 census was quite wide, and is generally viewed as two pages, but with one page number. The first page contains the name and the ages for the white families, and page two contains free colored and slaves and other data.

1840 Census Columns:

  1. Names of Heads of Families. This is usually the husband. If a woman is listed as head of household, she was usually a widow, or a single mother, or a single person raising younger siblings.
