Gender-Guess

Determine a person's gender based on a name. To determine if it is more likely male or female, it compares the name against the top 10,000 male and 10,000 female names from all US births 1930 - 2013. Data from the social security administration, so it works best for US names.

(If you want to make your own custom build of the names dataset, instructions to do this can be found in BuildData.md.)

Installation

npm install gender-guess

Usage

var gender = require('gender-guess')

gender.guess(name)

Examples

gender.guess('Thor')

=>
{
    name: 'Thor',
    gender: 'M',
    confidence: 0.9999
}
// Sorry Marvel, looks like Thor is still male.


gender.guess('Natasha')

=>
{
    name: 'Natasha',
    gender: 'F',
    confidence: 0.997
}

You can also include full names. It will take only the first part of the name (until the first space) to guess gender.

gender.guess('John Jacob Jingleheimer Schmidt')

=>
{
    name: 'John',
    gender: 'M',
    confidence: 0.9962
}

If it cannot find a name it will return all values as null.

gender.guess('Bilbo Baggins')

=>
{
    name: null,
    gender: null,
    confidence: null
}

Pro tip: some names are more ambiguous than others. Consider setting a limit in your code to only accept gender guesses that reach a certain confidence level. (In the future we'll add that as a native option.)
