Gender computer


Python tool that tries to infer a person's gender from their name (mostly first name) and location (country). For example, Andrea is a first name typically used by men in Italy and women in Germany, while Bogdan is a first name typically used by men irrespective of the country. Similarly, a Russian person called Anna Akhmatova is more than likely a woman because of the -ova suffix.

Data provenance

The tool uses lists of male and female first names for different countries. Whenever available, the data came from national statistics institutes and was accompanied by frequency information. See this list for details about the source of data for each country.

The tool also uses the database of first names from all around the world provided together with gender.c, an open source C program for name-based gender inference ( We transform the database (i.e., the nam_dict.txt file shipped together with gender.c; see the archive on into a Python dictionary using the script.



To use the tool simply create a new GenderComputer object and call the resolveGender method on a (name, country) tuple:

from genderComputer import GenderComputer
gc = GenderComputer(os.path.abspath('./nameLists'))

print gc.resolveGender('Alexei Matrosov', 'Russia')
> male

print gc.resolveGender('Matrosov Alexei', 'Russia')
> male

print gc.resolveGender('Bogdan', None)
> male

print gc.resolveGender('w35l3y', 'Brazil')
> male

print gc.resolveGender('Ashley Maher', 'Australia')
> female

The tool works well for clean names, but may produce unexpected results otherwise:

print gc.resolveGender('jasondavis', 'USA')
> None

print gc.resolveGender('aix', None)
> female
