United States name popularity data is provided by the Social Security Administration.
All names are from Social Security card applications for births that occurred
in the United States. Data for a given year is not made available until well into
the next year. Data reflects what was recorded and has not been
edited for errors, so for example the gender associated with a
name may be incorrect. The more babies that are given a particular name, the
higher the popularity ranking. If multiple names have the same usage,
the tie is broken by assigning popularity rank in alphabetical order. Therefore in
the case of names with fewer occurrences, names with the same number of occurrences
may have vastly different rankings because they will be interranked alphabetically.
To safeguard privacy, the SSA does not include names with less than 5 occurrences.|
