As America prepares for the 2012 Economic Census, the U.S. Census Bureau has created an embeddable infographic displaying many of the ways they track the economic health of the country. The graphic cites facts dealing with manufacturing, services, retail trade, construction, government and much more as seen through the numerous economic programs and surveys conducted by the  Census Bureau. Many of these economic statistics will be available on a new mobile app being released next week. Other "How Do We Know?" infographics include information on the Census Bureau's history of data collection, our nation's veterans and the American Community Survey.
