Re: Best source for US given name popularities? Project help needed
I think you are wrong about the SSA data being based on "1% of total births". The "Background Information" page on their site now says:
All names are from Social Security card applications for births that occurred in the United States after 1879. Names are restricted to cases where the year of birth, sex, State of birth (50 States and District of Columbia) are on record, and where the given name is at least 2 characters long. Many people born before 1937 never applied for a Social Security card, so their names are not included in our data. For others who did apply, our records may not show the place of birth, and again their names are not included in our data.
All data are from a 100% sample of our records on Social Security card applications as of the end of February 2007.
