The level of education within a community can impact crime rates. Higher educational attainment often correlates with lower crime rates, as it provides individuals with better job opportunities and alternatives to criminal behavior. While lower educational achievement rates tend to lead to higher crime rates. In Colby, 75.5% of people have completed high school, while 83% of people have completed high school nationally.
