Real names, real records

Every figure here comes from the 2010 US Census, which counted every surname held by at least 100 people. Before that, family names were written down by hand, one household at a time.

The counts, ranks and population shares on each page are the Census Bureau's. The meanings are summaries of the usual explanations, and they say so when a name has more than one source.
