Everything from the murder rate to plant productivity varies geographically. Researchers seeking such spatially linked data for the United States, in fields from public health to geology, should steer to this guide from the University of Arkansas, Fayetteville. The collection of links tallies hundreds of maps and Geographical Information Systems data sets held by federal, state, and local agencies. Examples include regional birth and death statistics for Alaska, changes in land cover along the shores of the Great Lakes between 1996 and 2001, and this Environmental Protection Agency map of streams damaged or threatened by pollution in Washington state. Most of the data sets and maps are free and accessible online.
