How we read a name

Every figure on this page comes from the U.S. Social Security Administration's public-domain record of names given to babies born in the United States from 1880 to 2024. The SSA only counts a name in a year if at least five babies received it.

Popularity & rank

The trajectory shows how many boys were named Wiliam each year. The peak year is simply the year that count was highest, and the rank is where the name sat among all boys' names in 2024.

Estimated average age

We estimate the typical age of living people with this name by combining how many were born each year with a rough survival curve. It's a useful approximation for "how old does this name feel," not a precise actuarial figure — that's why we always label it estimated.
