The ZIP code 75409, which encompasses Anna in Texas, has experienced significant population growth and urbanization over the past decade. The population data from 2010 to 2022 shows a consistent upward trend, more than doubling from 11,098 in 2010 to 24,367 in 2022. This growth has led to a corresponding increase in population density, from 140.37 people per square mile in 2010 to 308.21 people per square mile in 2022.

Based on the 2022 population density of 308.21 people per square mile, the ZIP code area can be classified as rural, characterized by larger living spaces, lower infrastructure density, and a community-oriented lifestyle centered around local schools and small businesses. The estimated 9,336 housing units in 2022, derived from the national average household size of 2.61, suggest a mix of single-family homes and some smaller multi-family dwellings.

The consistent population growth and increasing density over the years indicate a gradual shift towards a more suburban rural lifestyle. This transition is likely driven by factors such as proximity to larger urban centers, improved infrastructure, and a growing demand for a balance between rural openness and access to suburban amenities.
