When individuals grapple with the challenges of affording housing, they may find themselves compelled to resort to criminal activities as a means of addressing their financial hardships, including acts like theft or fraud. This predicament is particularly pronounced in areas where housing affordability poses a persistent issue, giving rise to heightened concerns regarding crime. In such instances, some individuals and families may find themselves constrained to reside in cramped or subpar housing conditions, exacerbating stress levels and potentially fostering domestic disputes and associated criminal incidents.
High rental costs can limit economic mobility, making it difficult for individuals to save money, invest in education, or access better job opportunities. This can perpetuate a cycle of poverty and increase the risk of involvement in criminal activities. In summary, high rental costs can create economic challenges, overcrowding, and neighborhood dynamics that may increase the likelihood of certain types of crime, particularly property crimes. In Decatur, the average rental rates are $1,104 per month, compared to the national average of $1,444.
