What this count includes
The Census Bureau’s surname table is a national statistical release. It counts people who reported Mcmahon as a last name and publishes only surnames occurring at least 100 times.
The values contain privacy-protecting statistical noise. They are excellent for understanding national frequency, but small differences should not be read as exact headcounts.
Demographic distribution describes the aggregate Census categories among bearers of the surname. It does not establish any individual’s identity, ancestry, or nationality.
