Roma-Los Saenz is a port of entry west of Mission on US 83 and the Rio Grande, directly across from Ciudad Miguel Alemn, Tamaulipas, Mexico, in southwestern Starr County. Roma and Los Saenz are actually two adjoining settlements that have incorporated jointly; Spanish is the primary language.
The population in Roma-Los Saenz has grown steadily from 2,154 in 1970 to 8,059 in 1990. Since 1979 a new water plant, a 500,000-gallon elevated water tank, a new fire and police building, and a new community center have been constructed.
By 1990 dry-land farming to the north, with 100,000 acres of irrigated river bottom around the city, provided a strong agricultural base.
