This study explores the nature of the relationship between the number of state-regulated mobile homes and per capita income, so as to determine whether higher-income parts of Illinois have more mobile homes than would be predicted by a recent BBC News article. It does so by identifying a simple way to determine the direction and strength of any relationship between mobile homes and per capita income, which that article assumes to be negative, if only at the county level in Illinois. The study, specifically, collects and analyzes mobile home data from Illinois and per capita income data from the U.S. Census. After combining these data, then using correlation coefficients, it finds a positive relationship—albeit with different intensities, based on whether the proxy for mobile homes in each county is the number of mobile home spaces or the number of mobile home parks in 2017.
