List Of Baby Names

A list of baby names given to tiny humans in Ruby. Based on data from:

This gem was extracted from Namestork. Namestork brings 9 names to you and your partner's inbox once a day at a time of your choosing. If you're looking to find the perfect name for your baby consider trying it.


Add this line to your application's Gemfile:

gem 'list_of_baby_names'

And then execute:

$ bundle

Or install it yourself as:

$ gem install list_of_baby_names


Get the first name from the Hadley data set:

hadley = ListOfBabyNames.hadley
hadley.size # => 258000

last = hadley.last # => "Sloane"
last.gender # => :female
last.year # => 2008
last.position # => 1000

Get "Addison" from the Behind the Name data set (Note: ranking is unsupported in this data set so -1 is returned for #year and #position):

behindthename = ListOfBabyNames.behindthename
behindthename.size # => 23355

addison = behindthename.find { |name| == "Addison" }
addison.gender # => :unisex
addison.year # => -1
addison.position # => -1

Get the list of data sets:

ListOfBabyNames.data_sets # => [:behindthename, :hadley, :south_australia, :queensland]

Scripts for transforming data sets into the common format are in script. These scripts are super hacky and mostly for my convenience.
