Land use--Middle West; Land capability for agriculture--Middle West


A cartographic analysis of fluctuations in cleared farm land acreage in each county of the Upper Lake slates al each census between 1910 and 1964 is based on standard deviations from the mean acreage for the county. The smallest relative fluctuations have occurred in counties with the largest percentages of their area in cleared farm land. Peak acreages were attained in most Michigan counties by the time of World War I, but acreages continued to increase in Wisconsin and Minnesota until World War II, and even since that time in some western Minnesota counties.
