Based on the historical population data for ZIP code 78379, which covers the Texas Riviera, the area has experienced a gradual increase in population and population density over the past decade. In 2010, the population was 1,456, with a density of 7.27 people per square mile. By 2022, the population had grown to 2,067, resulting in a density of 10.32 people per square mile.

Given the size of the ZIP code area (200.25 square miles) and the population density in 2022, the Texas Riviera can be classified as a remote rural area. Remote rural areas are characterized by very sparse populations, minimal infrastructure, and limited services. The lifestyle in such areas is predominantly agricultural or undeveloped, with a focus on privacy and self-sustainability. Common activities include outdoor and recreational pursuits due to the natural environment.

The estimated number of housing units corresponding to the 2022 population, based on the national average household size of 2.61, is approximately 792. This suggests that the area has a relatively low housing density, with large expanses of land per household, which is typical of remote rural areas.
