Most Mam (617,171) live in Guatemala, in the departments of Huehuetenango, San Marcos, and Quetzaltenango. The Mam people in Mexico (23,632) live principally in the soconusco region of Chiapas.
Many Mam live in and around the nearby modern city of Huehuetenango. The city of Quetzaltenango or Xela was originally Mam. Many more Mam live in small hamlets in the mountains of northern Guatemala, keeping many of their native traditions. Many Mam are bilingual and speak both Spanish as well as the Mam language, part of the Maya language family, the latter typically as their first language.
