Information About Indiana:

Indiana is located in the East North Central sub-region of the Midwest. According to the United States Census Bureau, the population estimates for Indiana as of July 1, 2016 was 6,633,053; and the population percent change from April 1, 2010 to July 1, 2016 is only 2.3%. According to Indiana University Bloomington, the population growth in 2015 was "sluggish," and the percent change was actually slower and smaller than the average growth over the last five to six years. According to InText, about two-thirds of the state is farmland. With a global population increase, it's a no-brainer that with more people comes more development, and more development leads to less farmland.

Information About Ohio:

Ohio is located in the East North Region of the Midwest, to the east of Indiana. According to the United States Census Bureau, the population estimates as of July 1, 2016 was 11,614,373; and the population percent change from April 1, 2010 to July 1, 2016 was 0.7%. Compared to the Indiana data above, Ohio has an approximate 45% higher population than Indiana, however the population change is significantly smaller. According to a local Ohio news station, WCPO Cincinnati, about 27,500 more people left Ohio than moved in during the 2016 fiscal year. The news station also had an interesting remark as to how the decrease in population could have had political implications, and lose the advantage of being a "swing-state."
