Methodology
How we calculated this
The first name Masayuki has a living-bearer frequency of 0.0000% of the US population, based on 8 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 Masayuki right now.
The surname Suo appears at a rate of 0.11 per 100,000 residents in the 2020 Census Bureau surname file, which translates to a frequency of 0.0001%.
Multiplying these two independent frequencies against the current US population of 342,754,338 gives an expected count of approximately 1 people with the full name Masayuki Suo. This assumes statistical independence between first and last names, which is a simplification but produces reasonable estimates for most combinations.
