In areas where employment options are limited or where a significant proportion of jobs offer meager wages, the likelihood of heightened unemployment and homelessness increases. Regions facing challenges related to unemployment or inadequate income may become more vulnerable to a surge in crime stemming from economic instability.

Rising cost of living expenses, including increased housing costs, grocery, utility and healthcare expenditures, can induce financial strain on individuals and families, particularly those with limited financial resources.

In Arlington, the cost of living is 79.11% higher than the national average, reflecting a more affordable economic environment that could contribute to a decrease in crime levels.
