Top Baby Names in Iowa, 1970s — Most Popular Boys & Girls Names

What the Data Says About the 1970s in Iowa

During the 1970s (1970–1979), the Social Security Administration recorded 242,108 births across the top 50 boy and top 50 girl names in Iowa. The decade's leading boy name was Jason with 8,578 births, while Jennifer was the top girl name with 9,684 births. The top 50 boys in this decade collectively accounted for 142,527 births versus 99,581 for the top 50 girls — a common SSA pattern in which the boy-name pool is more concentrated among fewer high-frequency choices. These totals represent only names appearing five or more times per year in Iowa; rarer names fall below the SSA's privacy-disclosure threshold and are excluded.

The 1970s sits within a specific cultural window of U.S. naming history. Mid-century decades like the 1970s spanned the post-war baby boom and the beginning of naming diversification, as parents increasingly departed from purely traditional choices. Jason and Jennifer leading Iowa during this window reflects how regional preferences interact with broader national trends.

Decade totals are computed by summing SSA state-year records for Iowa across all ten years of the 1970s. Because the SSA suppresses any name with fewer than five annual occurrences in a state, the true number of unique names given in Iowa during this decade is larger than what this page lists. The dataset also treats every spelling as a separate name — for example, Kayla and Kaylah are tracked independently — so combined-spelling totals would shift the rankings somewhat.
