Increasing the Reach of Census Bureau Data

Increasing the Reach of Census Bureau Data

Guest blog post by Raul Cisneros, director, Center for New Media and Promotion and Rebecca Blash, chief, Center for Enterprise Dissemination Services and Consumer Innovation (CEDSCI), U.S. Census Bureau

The U.S. Census Bureau is committed to operational excellence by making the statistics that define our growing, changing nation more accessible than ever before. In an age of instant communication and 24/7 information sharing, the needs and expectations of the Census Bureau’s data users have changed. We have listened to our customers, and this is what we have heard: Our users want easy access to timely, relevant statistics. They want access anywhere and anytime.  And, they want their data to be shareable, embeddable, downloadable and customizable.

In response, the Census Bureau has undertaken a comprehensive digital transformation effort, developing new tools using the latest technologies.  Almost 50 million people visit annually, and we’ve made major improvements to the site so that they can more easily find the information they want. We also created an application programming interface (API) to increase the accessibility and usability of our data. The API gives developers quick and easy access to an ever-increasing pool of publicly available data, allowing them to create Web or mobile apps. More than 7,000 developers have requested access to the API, and the databases have been queried more than 600 million times. Because these apps subsequently reach new users, they have the added benefit of increasing the circulation of our demographic, socioeconomic and housing statistics even more.

We also want to make our data accessible and appealing to as wide an audience as possible. Our three mobile apps are a good example of this. America’s Economy provides real-time updates of 20 key economic indicators, making it easy for casual or serious followers of the U.S. economy to see the latest trends. Our two other tools, dwellr (an app that helps users discover cities and towns that fit their lifestyle) and Census PoP Quiz (a population challenge quiz), tap into statistical information from the American Community Survey for casual data users.

Attention Developers: More Economic Statistics Added to BEA’s API

Developers, do you want to bring more detailed economic data to your next app? The Bureau of Economic Analysis (BEA) recently added several data sets to the application programming interface (API) we launched last year.

The API now provides direct access to the gross domestic product (GDP) underlying detail tables. Those tables contain a wealth of statistics, including how much consumers spend on hundreds of items like furnishings, food and flowers and how much revenue the government takes in and spends.

Other newly added data to the API are BEA’s national fixed assets, which include statistics on fixed assets like factory equipment, buildings, intellectual property and durable goods for consumers. 

The new additions give you the ability to create an even richer, customized economic dashboard of your own.

The new data sets join BEA’s GDP and related national economic statistics and regional economic statistics, which have been available via API since the service launched in May 2013. In addition to expanding the amount of data available on the API, BEA published an updated User Guide, making it easier for developers to start using the service.

BEA’s API allows developers to build a service to search, display, analyze, retrieve, or view BEA statistics. For example, you can create a “mashup” that combines BEA data with other government or private data sources to create new services or give your users a different perspective on their communities. Or you can design a tool that gives your users new ways to visualize economic data.

The API includes methods for retrieving subsets of BEA statistical data and the meta-data that describes it using HTTP requests. It delivers data in two industry-standard formats: XML (Extensible Markup Language) and JSON (JavaScript Object Notation).

To use the API, you need to register first. Full documentation is available in the updated API User Guide.

Census API lets developers create custom apps, reach new users

Commerce's U.S. Census Bureau has released a new online service that makes key demographic, socio-economic and housing statistics more accessible than ever before. The Census Bureau’s first-ever public Application Programming Interface (API) allows developers to design Web and mobile apps to explore or learn more about America's changing population and economy.

The new API lets developers customize Census Bureau statistics into Web or mobile apps that provide users quick and easy access from two popular sets of statistics:

  • 2010 Census (Summary File 1), which includes detailed statistics on population, age, sex, race, Hispanic origin, household relationship and owner/renter status, for a variety of geographic areas down to the level of census tracts and blocks.
  • 2006-2010 American Community Survey (five-year estimates), which includes detailed statistics on a rich assortment of topics (education, income, employment, commuting, occupation, housing characteristics and more) down to the level of census tracts and block groups.

The 2010 Census and the American Community Survey statistics provide key information on the nation, neighborhoods and areas in between. By providing annual updates on population changes the survey helps communities plan for schools, social and emergency services, highway improvements and economic developments.  Census press release
