Guide To Census Records

Delaware’s United States census material offers a wealth of information to a researcher. Genealogists find census records particularly useful for tracing family lines or histories in the state. Historians find them useful for local history information. Social scientists find them useful for demographics, ethnic studies, etc. Federal census records date from 1790 and continues every 10th year. As a general rule, the information in each successive census is progressively more detailed. The schedules for the period 1790-1840 show the names of enumerated heads of families only, and others in the household are tallied by characteristics (age groups, sex, and race). All subsequent enumerations, however, list each individual in a household by name. The most recent census available at the archives is 1940. Because they contain personal information, census records can only be released 72 years after their creation. Separately created indices are available in book form for the years up to and including 1870. After this point, researchers can access census records on microfilm or through Ancestry.com. Described below is the information that is relevant for certain census records years.
