Illinois Mortality Schedules - FamilySearch Historical Records

What is in This Collection?
The collection consists of an index and images to mortality schedules from Illinois from 1850 to 1880. Mortality schedules exist for the census year 1850, 1860, 1870, and 1880 for deaths in the year leading up to the census. Census enumerators requested information from the head of household about deaths that had occurred from June 1st to May 31st of the previous year. In 1918 to 1919, the Bureau of the Census distributed the original schedules to states or to the National Library of the Daughters of the American Revolution when states were not interested. Census mortality schedules are usually accurate, but this accuracy depended on the knowledge of the informant and the care of the census enumerator.

Mortality schedules list a small percentage of the total population. At the time of the 1870 census, it was surmised that as many as one-third of all deaths were not reported. For instance, when a family was scattered by the death of the head of household, there was no one left to report it. In 1880, a supplemental report from attending physicians added 60,000 additional names to the schedules.

In the absence of vital registration in many states, mortality schedules provided nationwide death statistics for one year of each decade, 1850–1880. According to the official statistical report for 1870, this was done to assess the death rate for age-groups, sex, race, nationality, and occupation and to "deduc[e] the effect of the various conditions of life upon the duration of life."
