Through our CitySDK, we are aiming to provide a user-friendly “toolbox” for civic hackers to connect local and national public data. The creation of the SDK came out of the desire to make it easier to use the Census API for common tasks that our developer community asked for. We have been engaging developers around the country for the past two years and have observed how they use the API and have built the most commonly needed functionalities usually put ‘on top’ of our API right into the SDK, saving the developer from having to do it herself.
