The data for this map was computed by a Perl program I wrote that matched first names in the FCC database of Amateur Radio licensees with a master list that categorizes them as male, female, or uncertain. For more of the story, see my article on the ARRLWeb .
In the tabular data below, some state codes may be unfamiliar. Consult the Official USPS Abbreviations for what the AA, AE, AP, AS, GU, MP, PR, and VI codes represent.
