data

A data object with keys corresponding to all the names given to male children born in the United States in the period from 1880-2014. All names are in lower-case letters. For each name, an array-of-arrays is exported with birth frequencies for each year. For years in which less than five children with a certain name were born, no data is available.

// Retrieve data for the name "Kaden"

Reference

The original data was collected by the Social Security Administration and is based on Social Security card applications for births that occurred in the United States after 1879. Since this data is based on government documents, it should be considered public domain.

Examples

// Frequencies for name `Herbert`
var freq,
    i;

freq = require('datasets-male-first-names-us-frequency/lib/herbert.json' );

for( i = 0; i < freq.length; i++ ) {
    console.log( 'Year: ' + freq[ i ][ 0 ] + '; Count: ' + freq[ i ][ 1 ] );
}
