What the Data Says About Baby Names in Arizona

The Social Security Administration has registered 1,325,405 births across the top 50 boy and top 50 girl names in Arizona from 1910 through 2025, the portion of state-level naming data released publicly. Among boys, Michael leads with 47,307 cumulative births, while Mary tops the girl rankings with 23,048 births. The top 50 boy names collectively account for 846,580 births versus 478,825 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 Arizona extends back to 1910, making it possible to track how Arizona parents' naming choices have shifted across more than a century of birth records. In the 1910s, the #1 boy name was John and the #1 girl name was Mary. By the 2020s, the top names had shifted to Liam for boys and Olivia 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 Arizona 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 Arizona 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.
