Methodology
How we calculated this
The first name Dudley has a living-bearer frequency of 0.0014% of the US population, based on 4,795 estimated living Americans carrying this first name (from SSA birth records going back to 1880, adjusted for mortality using CDC life tables).
Even though the Census Bureau now publishes first-name tables, we do not use that file as the main first-name input for this estimate. The latest first-name Census snapshot is from 2020, which makes it 6 years old today. Because Census first-name data is only released once every 10 years, SSA birth records plus CDC survival rates give a better current estimate of how many people are likely alive with the name Dudley right now.
The surname Murphy appears at a rate of 99.72 per 100,000 residents in the 2020 Census Bureau surname file, which translates to a frequency of 0.0997%.
Multiplying these two independent frequencies against the current US population of 342,754,338 gives an expected count of approximately 5 people with the full name Dudley Murphy. This assumes statistical independence between first and last names, which is a simplification but produces reasonable estimates for most combinations.
