What the Data Says About Baby Names in Iowa

The Social Security Administration has registered 1,825,858 births across the top 50 boy and top 50 girl names in Iowa from 1910 through 2025, the portion of state-level naming data released publicly. Among boys, Robert leads with 71,225 cumulative births, while Mary tops the girl rankings with 61,965 births. The top 50 boy names collectively account for 1,111,798 births versus 714,060 for the top 50 girl names, reflecting the typical U.S. pattern in which boy-name distributions are more concentrated among fewer high-frequency entries. SSA state files include any name appearing five or more times in a given state-year, so lower-frequency names are suppressed for privacy and are not counted in these totals.

Decade-by-decade data for Iowa extends back to 1910, making it possible to track how Iowa parents' naming choices have shifted across more than a century of birth records. In the 1910s, the #1 boy name was Robert and the #1 girl name was Mary. By the 2020s, the top names had shifted to Oliver for boys and Charlotte for girls. Across 12 decades with complete data, the turnover in #1 rankings reflects broader cultural and generational forces, baby-boom naming conformity, the 1970s individualism shift, and the current resurgence of short, classic names.

Because Iowa reports under the same SSA framework as every other jurisdiction, these figures are directly comparable across all 50 states and the District of Columbia. The cumulative totals reflect every recorded birth registration rather than a survey sample, though names with four or fewer annual occurrences are excluded per SSA privacy policy. This means the true naming distribution in Iowa is slightly broader than what appears here, particularly for rare and emerging names. The dataset does not distinguish between alternate spellings (for example, Sophia and Sofia are tracked as separate names) or middle names, and reflects first names as they appear on Social Security card applications only.
