Population change and farm dependence: temporal and spatial variation in the U.S. Great Plains, 1900-2000.

I investigate the relationship between county population change and farm dependence in the Great Plains region during the twentieth century, using spatial data analysis techniques. This research is rooted in a long-standing sociological and demographic interest in population responses to economic transitions and informs the theoretical understanding of urbanization processes. Using census and environmental data, the analysis challenges earlier assertions of a simple transition in the relationship between farm dependence and population change that accompanied modern technological advancements, namely tractors (the mechanization thesis).

Race, gender, and marriage: destination selection during the Great Migration.

Using historical census microdata, we present a unique analysis of racial and gender disparities in destination selection and an exploration of hypotheses regarding tied migration in the historical context of the Great Migration. Black migrants were more likely to move to metropolitan areas and central cities throughout the period, while white migrants were more likely to locate in nonmetropolitan and farm destinations. Gender differences were largely dependent on marital status.
