Governed as a prefecture-level city, as of the 2020 census, its built-up area made up of its 5 urban districts is home to 2,261,089 people with a total population of 2,709,378 accounting for counties under its jurisdiction. The city's namesake, literally translated to "place with deer", is of Mongolic origin or "Lucheng", meaning "City of Deer". Alternatively Baotou is known as the "City of Steel in Gobi". Steel was a major industry in the city. Today, Baotou refines over half of the rare-earth minerals produced in the world. This has led to environmental contamination near the industrial sites.
