About
Life in Four Square Mile
This unincorporated Arapahoe County community sits in that interesting pocket between Denver and Aurora—close enough to tap into metro resources, but with its own distinct identity shaped by its quirky political history and diverse resident base. With nearly 23,000 people and a median age around 32, you're looking at a younger, mixed demographic that includes significant single-parent and single-person households alongside families, which creates a different neighborhood vibe than typical suburban Denver. The job market here is solid with a 4% unemployment rate, and the median household income of $80,903 puts you in reasonable standing for the Front Range, though housing costs have climbed like everywhere else—expect median home values around $474,200 and rents near $1,833 monthly, which will eat up a meaningful chunk of that income.
