A large population of Bolivian and Bolivian-descended residents is in the Greater Washington, D.C.-Baltimore–Northern Virginia area of United States (2005 US Census estimates 27,452 +/- 8,883 Bolivians for DC, Virginia, and Maryland); the highest concentration is in Arlington County, Virginia. These figures may represent a census undercount of undocumented Bolivian alien residents. These combined communities have become the centre for recent and established Bolivian immigrants, most of whom are from the department and city of Cochabamba, hence, locally regarded as "Little Cochabamba" or "Arlibamba". Little Cochabamba contains Bolivian-cuisine restaurants and the Escuela Bolivia; a school-within-a-school programme for children and adults. Most of these migrants are Quechua, and come from the municipalities of Tarata, Arbieto, Tolata, Cliza, and Punata. The majority of them first migrated to Argentina before settling in the DC area. https://pulitzercenter.org/reporting/only-bridge-matters-now
