About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

CPS Wages Data

NPM version Build Status Coverage Status

A random sample of 534 workers from the Current Population Survey (CPS) from 1985.


npm install @stdlib/datasets-berndt-cps-wages-1985


var cps = require( '@stdlib/datasets-berndt-cps-wages-1985' );


Returns a random sample of 534 workers from the Current Population Survey (CPS) from 1985, including their wages and and other characteristics.

var data = cps();
// returns [{...},{...},...]

Each array element has the following eleven fields:

  • education: number of years of education.
  • south: indicator variable for southern region (1 if a person lives in the South; 0 if a person does not live in the South).
  • gender: gender of the person.
  • experience: number of years of work experience.
  • union: indicator variable for union membership (1 if union member; 0 if not a union member).
  • wage: log-transformed wage (in dollars per hour).
  • age: age (in years).
  • race: ethnicity/race ('white', 'hispanic', and 'other').
  • occupation: occupational category ('management', 'sales', 'clerical', 'service', 'professional', and 'other').
  • sector: sector ('other', 'manufacturing', or 'construction').
  • married: marital status (0 if unmarried; 1 if married).


  • Based on residual plots, wages were log-transformed to stabilize the variance.


var Plot = require( '@stdlib/plot' );
var dataset = require( '@stdlib/datasets-berndt-cps-wages-1985' );

var data;
var plot;
var opts;
var x;
var y;
var i;

data = dataset();

// Extract wage data...
x = [];
y = [];
for ( i = 0; i < data.length; i++ ) {
    x.push( data[ i ].age );
    y.push( data[ i ].wage );

// Create a plot instance:
opts = {
    'lineStyle': 'none',
    'symbols': 'closed-circle',
    'xLabel': 'Age',
    'yLabel': 'Wage',
    'title': 'Age vs Wage'
plot = new Plot( [ x ], [ y ], opts );
