The U.S. Census Bureau’s LEHD Program[1] and Center for Economic Studies[2] invite you to participate in a day of cutting edge data exploration and engagement on usability and visualization analytics using large scale economic data. This workshop is being held in coordination with the CREATE Lab at Carnegie Mellon University and will take place at the Census Bureau’s headquarters in Suitland, MD.

During the day, participants will learn to use Explorable Visual Analytics (EVA) – a free, open-source, web browser-based tool for data exploration and visualization that was built by CREATE Lab. Data for exploration will include the Residence Area Characteristics (RAC) from the public-use LODES dataset, which is produced by the LEHD Program and includes demographic and employment information on 120 million workers in the United States as well as their residential distribution. In total, the dataset comprises 2.7 millions entries and 46 dimensions (worker age, sex, race, ethnicity, and educational attainment; firm ownership and industry; and job earnings).

Invitees will take part in guided investigation of data for the Washington DC metropolitan area (DC, Delaware, Maryland, Pennsylvania, and Virginia).  The interactive and easy to use nature of EVA facilitates intuitive data exploration and leads to new forms of hypothesis generation and inquiry. Invitees will then be able to generate and explore their own questions from their diverse experiences, skill level, and professional expertise.

EVA will allow invitees to explore this data in space and time in variable resolutions, fluidly create new views by selecting desired data dimensions, and construct a narrative supported by a sequence of interactive visualizations. Because EVA will be publicly available, invitees will be able to continue using the tool to share big data tours on standard web browsers after the workshop is complete. It will also be possible to host data using EVA’s visualization engine on invitees’ own websites and an afternoon session will be held to discuss the technical considerations and requirements for doing so.

The LEHD program produces new, cost effective, public-use information combining federal, state and Census Bureau data on employers and employees under the Local Employment Dynamics (LED) Partnership. State and local authorities increasingly need detailed local information about their economies to make informed decisions. The LED Partnership works to fill critical data gaps and provide indicators needed by state and local authorities.
