How We Estimate Full-Name Frequency
Because privacy laws prevent the release of individualized master population rosters, statistical demographic models use the law of independent probabilities to estimate full-name frequencies:
1. First-Name Frequency: Based on historical SSA birth registrations adjusted by CDC life table actuarial survival rates.
2. Surname Frequency: Based on official U.S. Census Bureau decennial surname tabulations.
3. Mathematical Note: First and last names do not always distribute with complete independence across all ethnic sub-populations. This figure represents an evidence-grounded statistical estimate rather than an exact physical roll-call.
