How we calculated this

The first name "Lorna" has an estimated frequency of < 0.0001% among living Americans, based on SSA birth records from 1880 to 2024 adjusted for mortality using CDC 2023 life tables.

The surname "Cook" appears at a rate of 97.15 per 100,000 people in the 2020 U.S. Census.

We do not use the Census first-name snapshot for the main estimate because it is only published once every 10 years.

SSA birth records plus CDC survival data give a better current estimate of how many people with the first name Lorna are likely to be alive now.

Multiplying these frequencies against the U.S. population of ~343 million gives 15 estimated people. This assumes first names and last names are statistically independent. Full methodology.
