People of Rio Grande City, TX
Today, Rio Grande City is a densely Hispanic community of 15,258 residents, with 96.6% identifying as Hispanic and only 2.6% as White alone, giving it a rare example of a border town where the population has remained overwhelmingly Mexican-American for generations.

The Las Lomas neighborhood, just west of downtown, grew as a colonia in the early 1900s, housing Mexican laborers who worked on nearby ranches and farms. By the mid-mid-20th century, the population was overwhelmingly Mexican-American, with a small Anglo elite controlling most business and political power. The Original Townsite area, the city's first platted grid of streets, saw extended families subdividing lots as the population densified through natural increase.
Modern era (post-1965)
The 1965 Hart-Cellar Act ended national-origin quotas, but for Rio Grande City the more significant driver was the steady flow of migration from Mexico fueled by economic push factors and family reunification. The La Puerta neighborhood, east of downtown, expanded rapidly in the 1970s and 1980s as a colonia without paved roads or utilities, absorbing newly arrived immigrants. The Original Townsite area gradually densified as families subdivided homes to accommodate multiple generations. The 1990s brought the first wave of middle-class flight to newer subdivisions along the US-83 corridor, such as the La Victoria neighborhood, where
