Population and Environment in the U.S. Great Plains analyzes the recursive relationships between environment, population, and land use in the Great Plains, a semi-arid grassland covering roughly one-third of the United States, over a period of about one hundred and fifty years. The project team includes historians, sociologists, anthropologists, and demographers at the University of Michigan, Colorado State University, and the University of Saskatchewan, with consultants at other universities. The project was funded by the National Institute of Child Health and Human Development. Learn more on the main project website at http://www.icpsr.umich.edu/icpsrweb/PLAINS/.
