A trip through the data wringer

In an attempt to investigate why some rural counties have fared well and others poorly in the last decade, fedgazette looked into a number of variables that might start to suggest some answers.

In each case, data on a certain variable (like presence of an interstate highway or Native American casino) were gathered and sliced in different ways to see how data relationships changed as the grouping of counties changed, particularly for rural counties ranking in the top and bottom 30 percent for both population and per capita income growth.

Although the variables described above show some distinct patterns and trends, they do not—either individually or collectively—conclusively prove why some counties are doing well and others are not. Such an undertaking requires the complicated task of controlling for innumerable social, economic and even weather variables that ultimately contribute to the wealth and well-being of individuals and communities. As such, research focused exclusively on correlative factors (the likelihood of something being present or absent) rather than causal relationships.

This research effort was not intended to identify all the factors responsible for growth (or lack thereof) nor was it intended to identify and align all the cause-effect relationships at play. It was done to offer insight on growth trends in the Ninth District beyond mere demographic patterns found in the latest census.

See data spreadsheet for all counties on the variables described above.
