About the Rio Grande Valley . The Rio Grande Valley is a region of small towns in South Texas with a unique cultural identity. Located along the Rio Grande River and the Gulf of Mexico, it’s home to almost 2 million people. The majority of the population is latino, of which 28,000 are DACA recipients. People from here tend to refer to themselves as being from “the Valley,” rather than the specific tiny town named by a white settler.
