In the top 10 at the same time
Source: US Social Security Administration baby-name data, from Social Security card applications for births in the 50 states and the District of Columbia, 1880–2025. Many people born before 1937 never applied for a card, so early years undercount. Spellings are counted separately. We hold each year's top 10 in rank order and each name's peak-year and all-time counts, so the chart shows rank rather than births per year. This page gives no meaning or origin for the name and no estimate of how many people named Susan are alive today.
