Zip code 78730 in Austin, Texas, is categorized as having a "White Majority" with 70% of the population identifying as white as of 2022. The area has a high median income of $141,562 in 2022, which is above national averages. This affluent suburb has experienced moderate demographic shifts over the past decade, moving towards increased diversity while maintaining its status as a predominantly white, high-income area.
Over the past decade, zip code 78730 has gradually transitioned from a "Low Diversity" area to one of "Moderate Diversity." In 2013, the white population comprised 84% of residents. By 2022, this percentage decreased to 70%, indicating a slow but steady increase in racial diversity. The Hispanic population has shown the most significant growth, increasing from 7% in 2013 to 15% in 2022. The Asian population has also grown slightly, from 6% to 8% over the same period.
The area is showing signs of becoming a "Transitional Community," particularly with the consistent growth in Hispanic and multiracial populations. The median income peaked in 2019 at $169,428 before declining to $141,562 in 2022. Despite this recent decline, the area remains highly affluent. The consistently high median income levels suggest that the increasing diversity is likely driven by high-income individuals from various racial backgrounds moving into the area, rather than a significant socioeconomic shift within the existing population.
The population has grown steadily from 8,354 in 2010 to 10,023 in 2022, a 20% increase. This growth, combined with the diversity trends, suggests that the area is attractive to a widening demographic of high-income earners.
The trends observed in zip code 78730 align with broader patterns seen in many affluent suburbs across the United States. Many traditionally white, high-income areas are experiencing gradual increases in diversity, particularly among Asian and Hispanic populations. This often reflects changing patterns of educational and economic achievement among these groups.
The persistence of high median incomes in this zip code suggests that this diversification is occurring primarily among high-earning professionals. The area's evolution towards greater diversity, while maintaining its economic status, may be indicative of Austin's growing reputation as a tech hub and its ability to attract diverse, high-skilled professionals. This gradual change suggests a carefully managed growth pattern that maintains the area's desirable economic characteristics while slowly increasing its racial and ethnic diversity.
