Why is the Census count different from the living estimate?
Because they measure different things. The Census number is a count of people with the name in 2020. The living estimate is a current model based on SSA birth records and survival rates, so it aims to estimate how many people with the name are alive now.
What does the SSA popularity chart show?
The popularity chart tracks birth registrations, not people currently alive. It shows how often Rudolph was given to babies from 1880 through 2024, which is why it is the best tool on the page for seeing long-run naming trends.
What does the Census say about the gender split for Rudolph?
In the 2020 Census snapshot, Rudolph was recorded as predominantly male. The published split was 99.8% male and 0.2% female.
What does the Census say about the background of people named Rudolph?

These percentages describe the people who had the name in the 2020 Census, not the deeper meaning or origin of the name itself.
Why can the Census sex total and race total differ slightly?
The Census published separate first-name tables for sex and for race and Hispanic origin. Those totals can differ slightly for the same name, so the page uses them as two related snapshots rather than treating them as perfectly interchangeable counts.
Does every first name have Census demographic data?
No. The public Census first-name tables only include names that met the Bureau's publication rules. That means some names on this site will have SSA history but no published Census demographic snapshot.
Is Rudolph a male name?
Rudolph is predominantly male. 99.6% of people with this name are male. See the gender breakdown above for full details.
Why can Rudolph have a lot of living bearers even if it is not trendy now?
Because a name can build up a large population over many decades. Rudolph peaked in 1927, and the average living bearer is about 65 years old, so a name can still have millions of living bearers even after it stops feeling current for newborns.
