The plains states rank well generally for income mobility according to a new study considered to be the most comprehensive yet on the subject.  Based on millions of anonymous income records, the study by leading economists found four primary factors correlated with higher income mobility in an area: a larger and more dispersed local middle class, more two-parent households, better elementary schools and high schools, and more civic engagement, including membership in religious and community groups.
