CitySDK - US Census Bureau

Overview

This example demonstrates two key concepts used in the Census Module of the CitySDK: sublevels and normalization.

Sublevels

Specifying a sublevel allows you to enter a location (such as State) and get values that are one level below (i.e. County). This is helpful because it's not always obvious how to specify the sublevels when making an API call, as you wouldn't normally memorize county names.

Normalization

Some data from the Census American Community Survey (ACS) provide a return value in a special unit of measure that is averaged out across the population. In this case, Commuting data can be returned in a normalized fashion which equates to "avg minutes of commute per person".

1. Select Location

Specify Location By
Coordinates
State Code

Latitude:

°N

Number - The latitude of the requested location (North). Also supported: latitude, y Longitude:

°E

Number - The longitude of the requested location (East). Also supported: longitude, x

State:

String - The 2-letter USPS state code. It will be converted into the latitude and longitude of that state's capital.

Some common co-ordinates:
Name	Lat (N)	Lng (E)
Washington DC	38.9047	-77.0164
Seattle	47.6097	-122.3331
Honolulu	21.3000	-157.8167
Miami	25.7753	-80.2089
Houston	29.7604	-95.3698

                            var census = sdk.modules.census;
                            census.enable("Your API Key Here");

                            var request = ;

                            census.APIRequest(request, function (response) {

                            //Outputs the raw JSON text
                            jQuery("#rawOutput").append(JSON.stringify(response));

                            });
                            </script>
