The Rio Grande Valley is an area located in the southernmost tip of Texas. It lies along the northern bank of the Rio Grande, which separates Mexico from the United States.
The Rio Grande Valley is not a valley, but a delta or floodplain. Early settlers from Mexico felt that the term "Valley" sounded more inviting to tourists and northern investors than did "Delta." The Rio Grande Valley is also called "El Valle", the Spanish translation of "the valley", by those who live there. Another affectionate term that the residents of the Rio Grande Valley use to refer to the area is the "RGV."
The region is made up of four counties: Starr County, Hidalgo County, Willacy County, and Cameron County. As of January 1, 2007, the Texas State Data Center estimated the population of the Rio Grande Valley at 1,139,581.[1] Over 80% of the residents of the Valley are Hispanic or Latino.
