With a population of 27,291 at the 2010 census, it is the largest city between Midland to the west, Abilene to the east, Lubbock to the north, and San Angelo to the south. Big Spring was established as the county seat of Howard County in 1882; it is the largest community in the county.The city got its name from the single, large spring that issued into a small gorge between the base of Scenic Mountain and a neighboring hill in the southwestern part of the city limits. Although the name is sometimes still mistakenly pluralized, it is officially singular. "To the native or established residents who may wince at the plural in Big Spring, it should be explained that until about 1916, when for some unexplained reason the name dropped the final 's', the official name of the town was indeed Big Springs.
