This page is dedicated to providing access to preliminary Birth, Marriage, Fetal Death, and Death totals from 2017 through the current registration time period. Preliminary data is statistical vital record data published prior to the close of the year-end statistical file. This data will change as vital records are registered. New preliminary numbers will be released 30 days after the end of the month. The preliminary data shown below represents occurrence data (births, deaths or marriages that occur in Iowa). The data does NOT show residence data (births, deaths or marriages of people who reside in Iowa).
