There are multiple census indexes available on microfilm at various repositories across the state. However, the 1830 AIS indexes are not accurate. They list several Atlantic records under Bergen County records. The 1850 records are missing Camden County and Winslow Township records. The 1860 records are missing part of the records for Middlesex County. Copies of all of those records can be found at the Newark Public Library, the New Jersey Historical Society, the New Jersey State Archives, and Rutgers University. The state archives is also home to the Essex County copy of the 1850 federal census, the state copies of the 1850 and 1870 federal census records, the 1880 federal census records for Ocean and Essex counties, and the original 1880 population schedules.
The Monmouth County Archives holds copies of the abbreviated 1880 census records for that county. The state library and state archives each have microfilms and originals of the agricultural, manufacturing, and mortality schedules for 1880. The New Jersey State Archives and the New Jersey State Library are also home to the defective, dependent, and delinquent schedules for that year.
The Genealogical Magazine of New Jersey has published both the 1850 and 1860 Mortality Schedule Index. Mortality schedules from 1850 for people who died in other states but were born in New Jersey are also listed in that journal, beginning in volume 52 on page 71. Most of the 1890 federal census records no longer exist, but some of the records for Jersey City, Hudson County for that year are still available.
