First and Last Names Database

To download the raw CSV data for your analysis, browse here.

This Python library provides information about names:

• Popularity (rank)
• Country (105 countries are supported)
• Gender

It can give you an answer to some of those questions:

• Who is Zoe? Likely a Female, United Kindgom.
• Knows Philippe? Likely a Male, France. And with the spelling Philipp? Male, Germany.
• How about Nikki? Likely a Female, United States.

Composition

730K first names and 983K last names, extracted from the Facebook massive dump (533M users).

Installation

Available on PyPI:

pip install names-dataset

Usage

NOTE: The library requires 3.2GB of RAM to load the full dataset in memory. Make sure you have enough RAM to avoid MemoryError.

Once it's installed, run those commands to familiarize yourself with the library:

from names_dataset import NameDataset, NameWrapper

# The library takes time to initialize because the database is massive. A tip is to include its initialization in your app's startup process.
nd = NameDataset()

print(NameWrapper(nd.search('Philippe')).describe)
# Male, France

print(NameWrapper(nd.search('Zoe')).describe)
# Female, United Kingdom

print(nd.search('Walter'))

API

The search call provides information about:

• country: The probability of the name belonging to a country. Only the top 10 countries matching the name are returned.

• gender: The probability of the person to be a Male or Female.

• rank: The rank of the name in his country. 1 means the most popular name.

• NOTE: first_name/last_name: the gender does not apply to last_name.

The get_top_names call gives the most popular names:

• n: The number of names to return matching some criteria. Default is 100.
• gender: Filters on Male or Female. Default is None (both are returned).
• use_first_names: Filters on the first names or last names. Default is True.
• country_alpha2: Filters on the country (e.g. GB is the United Kingdom). Default is None (all countries are returned).

The get_country_codes returns the supported country codes (or full pycountry objects).

• alpha_2: Only returns the country codes: 2-char code. Default is False.

Full dataset

The dataset is available here name_dataset.zip (3.3GB).

• The data contains 491,655,925 records from 106 countries.
• The uncompressed version takes around 10GB on the disk.
• Each country is in a separate CSV file.
• A CSV file contains rows of this format: first_name,last_name,gender,country_code.
• Each record is a real person.

License

• This version was generated from the massive Facebook Leak (533M accounts).
• Lists of names are not copyrightable, generally speaking, but if you want to be completely sure you should talk to a lawyer.
