The data in this series of studies were assembled by an interdisciplinary research team led by Myron Gutmann of the University of Michigan between 1995 and 2004, as part of a research project funded by the National Institute of Child Health and Human Development (Grant Number R01 HD33445 to the University of Michigan). The goal of the project was to amass information about approximately 500 counties in 12 states of the Great Plains of the United States, and then to analyze those data in order to understand the relationships between population and environment that existed between the years of about 1870 and 2000. The data distributed here are all data about counties. They fall into four broad categories: about the counties, about agriculture, about demographic and social conditions, and about the environment. The information about counties (name, area, identification code, and whether the project classified the county as part of the Great Plains in a given year) is embedded in each of the other data files, so that there will be three series of data (agriculture, demographic and social conditions, and environment), containing individual data files for each year for which data are available. The United States Census of Agriculture has been conducted since 1850 on a regular schedule that was decennial until 1920, and more frequently thereafter (every five years from 1925 to 1950, then in 1954, 1959, 1964, 1978, and every five years since 1982). The agricultural data included in this collection consist of a single data file for each agricultural census year between 1870 and 1997 that includes selected material compiled as part of the United States Agricultural Census. The county-level agricultural data produced by the United States government as part of the census constitute a consistent series of measures of changing agriculture and land use.
