The Iowa vital records system originated on 1 July 1880. Marriages were recorded in the counties prior to 1880, typically beginning when the county started keeping other records as well. Early birth records contain only minimal data: name, date, place, and names of parents. Death certificates prior to 1904 do not include the names of the parents of the deceased.
It is estimated that between 1880 and 1921 only about fifty percent of the births and deaths were registered. However, because of a provision for delayed birth registration, almost 470,000 delayed birth records have been filed with the Bureau of Vital Statistics.
Many of the local chapters of the Iowa Genealogical Society have publications of vital records in their respective counties. A statewide publication listing with ordering information, is available through the state society on its website.
Ancestry.com and FamilySearch.org has a variety of collections available online. I’ve provided the links below.
The first Federal Population Census was taken in 1790, and a census has been taken every ten years since. However, data from recent censuses are not available after 1940 because of a 72-year restriction on access to the census.
The censuses prior to 1850 only list the head of household. Other household members are merely counted in selected age groups.
The 1890 Census was mostly destroyed by fire.
From 1850 forward are provided for all individuals in each household.
Mortality schedules recorded deaths in the year preceding the taking of the census. For example, the 1860 mortality schedules include persons who died between June 1, 1859, and May 31, 1860.
Tip: Begin with the most current census year available and work backwards.

Iowa County Resources from the Red Book. This link provides you with all Iowa counties, when they were formed, their parent county (ies), and when they began requiring Birth, marriage, death, Land, probate and court records. Your ancestor may have been born in one county, but records are kept in another, due to a change in county borders.
