Popularity is chosen by consensus

The Social Security Administration publishes a list of popular baby names. Fine. If you do a search for a given year there’s a little notice at the bottom: “Note: Rank 1 is the most popular, rank 2 is the next most popular, and so forth.” Wow… I want to complain that this is ambiguous and see if they’ll add “popularity is determined based on the total number of children with a given name”.
