Why is the Census count different from the living estimate?

The next largest recorded groups were Hispanic (5.52%) and Two or More Races (3.79%).

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 Callaghan a male name?

Why can Callaghan 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. Callaghan peaked in 2022, and the average living bearer is about 11 years old, so a name can still have millions of living bearers even after it stops feeling current for newborns.
