Population Schedules
. Many federal census records are at the Family History Library, the National Archives, and other federal record centers and state archives. The United States Research Outline (30972) provides detailed information about these records.
The Family History Library has the U.S. federal censuses of Delaware for 1800, 1810, 1820, 1830, 1840, 1850, 1860, 1870, 1880, 1900, 1910, and 1920. The 1790 census is missing, and the 1890 census was destroyed. A substitute for the 1790 census created from tax lists is:
Devalinger, Leon, Jr. Reconstructed 1790 Census of Delaware. Washington, D.C.: National Genealogical Society, 1962. (FHL book 975.1 X2d 1790; film 1000156; fiche 6019928; computer number 113633.)
Statewide indexes
are available in two forms:
One of the indexes for the 1850 census is:
Olmstead, Virginia L. Index to the 1850 Census of Delaware. Baltimore: Genealogical Publishing, 1977. (FHL book 975.1 X22o 1850; computer number 334423.) Indexes for the three counties are listed separately. An every-person index is given for each of the counties, with age, birthplace, and the original census sheet number. The New Castle County 1850 census is on two rolls of microfilm with some duplication of page numbers. You can use a different 1850 census index to find the township.
Countywide indexes
sometimes help you locate names overlooked in statewide indexes. A few countywide indexes are listed in the Locality Search of the Family History Library Catalog under DELAWARE, [COUNTY] - CENSUS.
When indexes are not available or omit a name you can still look for the name in the census. In large cities it helps to first learn the person's address by searching the city directory for the same year as the census (see the “Directories” section of this outline). Then look for that address on the original census schedules.
These reference tools help determine which census schedule microfilm and enumeration district to search for specific addresses:

Mortality Schedules
. Mortality schedules for 1850, 1860, 1870, and 1880 are at the Delaware Public Archives, the Historical Society of Delaware, and on microfilm at the Family History Library. The 1870 and 1880 schedules are indexed in:
Jackson Ronald Vern. Delaware 1870 Mortality Schedule. Bountiful, Utah: Accelerated Indexing Systems, 1981. (FHL book 975.1 X2j 1870; computer number 453832.)
Jackson Ronald Vern. Delaware 1880 Mortality Schedule. Bountiful, Utah: Accelerated Indexing Systems, 1981. (FHL book 975.1 X2j 1880; computer number 453833.)
Slave Schedules
. Slave schedules for 1850 and 1860 list the names of slave owners, but do not normally list the names of the slaves. The numbers of slaves, their gender, and their age ranges are given. Look in the Locality Search of the Family History Library Catalog under Delaware, CENSUS RECORDS, MINORITIES, SLAVE SCHEDULES.
The 1850 and 1860 slave schedules are indexed in:
Jackson, Ronald Vern. Delaware 1850-1860 Slave Schedules. Salt Lake City: Accelerated Indexing Systems International, 1986. (FHL book 975.1 X22j; computer number 417827.)

Master Indexes
. Some of the indexes mentioned above are combined into composite master indexes of several census years, states, and census types:
