Rio Grande Valley

The Lower Rio Grande Valley (Spanish: Valle del Río Grande), often referred to as the Rio Grande Valley (RGV) of South Texas, is a metropolitan region located in the southernmost part of Texas. It is located along the border of Texas with Mexico located in a floodplain of the Rio Grande near its mouth. It consists of the Brownsville-Harlingen and McAllen-Edinburg-Mission metropolitan areas, and the Rio Grande City-Roma and Raymondville micropolitan areas. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations. It is home to some of the poorest cities in the United States, as well as many unincorporated, persistent poverty communities called colonias. A large seasonal influx occurs of "winter Texans" – people who come down from the north for the winter and then return north before summer arrives.
