I Found Who I Was Looking For, What Now?

 * Use the age listed to determine an approximate birth date. This date along with the place of birth can help you find a birth record. Birth records often list biographical and marital details about the parents and close relatives other than the immediate family.
 * Birth places can tell you former residences and can help to establish a migration pattern for the family.
 * Use the race information to find records related to that ethnicity such as records of the Freedman’s Bureau or Indian censuses.
 * Use the naturalization information to find their naturalization papers in the county court records. It can also help you locate immigration records such as a passenger list which would usually be kept records at the port of entry into the United States.
 * If they are subject to military service they may have military files in the State or National Archives.
 * Occupations listed can lead you to employment records or other types of records such as school records; children’s occupations are often listed as “at school.”

I Can't Find Who I'm Looking For, What Now?

 * Check for variant spellings of the surnames.
 * Check for another index. Local genealogical and historical societies often have indexes to local records.
 * Search the indexes and records of nearby counties.
 * Try alternative search methods such as only filling in the surname search box (or the given name search box) on the landing page leaving the other box empty and then click on search. This should return a list of everyone with that particular name. You could then browse the list for individuals that may be your ancestor.
 * There is also the possibility that a family was missed in the census.

General Information About This Collection
Federal census takers were asked to record information about all those who were in a household on the census day, which was April 1 for the 1940 census. A census taker might have visited a house on a later date, but the information collected was supposed to have been about the people who were in the residence on the census day. The basic census enumeration unit was the county. Each county was divided into enumeration districts, one for each enumerator. The completed forms were then sent to the Census Office of the Commerce Department in Washington, D.C. The 1940 census covers 95 to 97 percent of the population.

Population schedules consist of large sheets with rows and columns. The schedules are arranged by state, county, place, and enumeration district. The districts are not always filed in sequential order. The arrangement of families on a schedule is usually in the order in which the enumerator visited the households.

The 1940 United States Census Population Schedules include: all states plus American Samoa and Guam, Consular Services, Panama Canal Zone, Puerto Rico, and the Virgin Islands.

The U.S. federal census has been taken at the beginning of every decade, beginning in 1790, to apportion the number of representatives a state could send to the House of Representatives. In the absence of a national system of vital registration, many vital statistics and personal questions were asked to provide a statistical profile of the nation and its states.

Federal censuses are usually reliable, depending on the knowledge of the informant and the care taken by the census enumerator. Realize that any family member or even a neighbor may have supplied information to the census taker. Some information may have been incorrect or deliberately falsified.
