How it is measured
The counts come from Social Security card applications, tabulated by the SSA by year of birth, name, and sex. It is administrative data, not a survey: every point is actual registrations. Two caveats shape the edges: names with fewer than five occurrences in a year are withheld for privacy, and the earliest decades undercount births because Social Security began in 1935 and older people applied late or never.
What the curve shows
Name data is one of the cleanest cultural time series in existence, and the curves behave like fashion: a rise usually has a traceable trigger, a famous namesake or a character, and the decay is slow because names linger in families after they leave the zeitgeist. Mason is past its peak, running at roughly 32 percent of its 2011 high.
