Simple ruby wrapper for the USA TODAY Census API. You'll need an API key.
- gem install usatoday-census
require 'rubygems' require 'usatoday-census' include Usatoday::Census
You'll want to set your API key as an environment variable in order to run the tests. Otherwise, you'll need to set it like so:
Base.api_key = YOUR_API_KEY
or via an environment variable:
API_KEY = ENV['USAT_CENSUS_API_KEY'] Base.api_key = API_KEY
The gem queries the USA TODAY Census API to return information about a state's population, ethnicity, housing, racial composition and other geographic details, including the USA TODAY Diversity Index. Requests return an array of results and the default geographic level is statewide. Users can search for a state by its postal abbreviation or name. To request results for other geographic levels (National, County and City or Town), you can pass the corresponding "sumlevid" to the search method. The following all return an array consisting of a single object containing statewide results:
Location.search('va') # find demographic information about Virginia Ethnicity.search("Virginia", "Placename") # can also search by full state name using the Placename attribute. Race.search("51", 'FIPS') # Or search by FIPS code, too.
These requests return an array of result objects at the county level:
Location.search('va', nil, 3) # find demographic information about Virgina counties using the state abbreviation. Ethnicity.search("Virginia", "Placename", 3) # find ethnicity information for Virginia counties.
Check out the tests for further examples. Run the tests via rake test. Note: you'll need to set your API key as an environment variable before running the tests. The API has a limit of two queries per second, so the test requests are delayed by one second to ensure passage.
Note on Patches/Pull Requests
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
