The 1860 census is one of the most accurately named US censuses of the 1800s. This is because all of the data was actually collected in 1860. Many previous censuses took over a year, but the 1860 census started on June 1 of that year and took only 5 months to complete.
The 1860 census contained a lot of the same questions from 1850, such as name, sex, color, real estate value, state, territory and country of birth. Marriages that took place that year, criminal histories, physical and mental competency and slave information were also included.
