How We Estimate State Surnames
The US Census Bureau publishes national surname frequency data along with ethnic/racial distribution percentages for each surname. We combine this with Iowa's demographic composition from the 2020 Census to estimate which surnames are most common in the state.
This approach, known as Bayesian Improved Surname Geocoding (BISG), is widely used in academic research and government applications. While individual estimates may vary, the overall rankings provide a reliable picture of surname prevalence in Iowa.
Data sources: US Census Bureau Decennial Census 2010 (surnames) and 2020 (state demographics).
