How many people are named Lonnie, and how old are they?
56,000 alive in 2026, estimated
That is 55% of the 101,481 Americans ever recorded as Lonnie. The median Lonnie alive today is 62 years old; half are between 50 and 73.
The 2020 Census counted 51,396 people named Lonnie (3,349 women and girls, 48,047 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 62,714 born in the U.S. The Census count is 18% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).

Where Lonnie is more common than its national share predicts
Relative to its national share, Lonnie is most over-represented in Arkansas: since 1910 it was given 2.4 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Lonnie with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 3 names spelled alike, given to 108,180 babies since 1880, Lonnie is the most given (94% of them). In 2025 it was given to 109 of their 114 babies (96%), again the most given.
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026.
