How to Use the Data USA API

Data USA is a website that provides access to comprehensive, open-source data about the United States. They offer an API that allows developers to access this data programmatically in order to build their own applications. In this blog post, we will explore how to use the Data USA API and provide some example code in JavaScript.

Getting Started

Before using the Data USA API, you will need to sign up for a free API key. You can do this by visiting the Data USA API website and clicking on the "Get API Key" button. Once you have your API key, you can start making requests to the API.

Example Code

Here are some examples of using the Data USA API in JavaScript:

Get All Counties in the United States

const apiKey = "YOUR_API_KEY";
fetch(`https://api.datausa.io/api/?show=counties&required=geo`)
  .then(response => response.json())
  .then(data => console.log(data.data))
  .catch(error => console.error(error));

This code will fetch a list of all counties in the United States and print the data to the console.

Get All Jobs in a State

const apiKey = "YOUR_API_KEY";
const state = "NY"; // Replace with the two-letter abbreviation for the state you are interested in

fetch(`https://api.datausa.io/api/?show=jobs&geo=${state}&required=geo`)
  .then(response => response.json())
  .then(data => console.log(data.data))
  .catch(error => console.error(error));

This code will fetch a list of all jobs in the state of New York and print the data to the console. You can replace "NY" with the two-letter abbreviation for any other state.

Get All Degrees Awarded in a Field

const apiKey = "YOUR_API_KEY";
const field = "engineering"; // Replace with the field you are interested in

fetch(`https://api.datausa.io/api/?show=degrees&required=grads_total&sumlevel=all&field_of_study=${field}`)
  .then(response => response.json())
  .then(data => console.log(data.data))
  .catch(error => console.error(error));

This code will fetch a list of all degrees awarded in the field of engineering and print the data to the console.

Conclusion

The Data USA API is a powerful tool for accessing comprehensive data about the United States. With these examples and your own creativity, you can use this data to build applications that help solve real-world problems.
