Fundamentals of Census Geography and TIGER Topology

Monday, October 22 , 1:00 P.M. - 5:00 P.M.
Location: J.J. Pickle Research Center
Taught by:
James Castagneri & Lacey Loftin
The MAF/TIGER system is the foundation for the decennial census and for the American Community Survey (ACS) among others. Created through a cooperative program with the United States Geological Survey (USGS) in the 1980’s, TIGER and census demographic data are now a critical part of the planning landscape. This workshop will explore the details of census geography and TIGER topology. We will answer questions such as; How do political and statistical geographies relate within TIGER? What happens to census blocks when a city submits a new annexation? And; Why did my CDP change shape in-between censuses? Bring your tough questions about TIGER and Census geography for an answer packed session designed to help you make the most out of TIGER data!
