Chiapas is a state in southern Mexico. According to the 2020 INEGI census, it has the eighth largest population of all states with inhabitants and the 10th largest by land area spanning 73560.47 km2. Chiapas is officially divided into 124 municipalities, although the establishment of municipal authorities in Belisario Domínguez was suspended in 2015 pending the resolution of a territorial dispute between Chiapas and the neighbouring state of Oaxaca. In 2021, the Supreme Court resolved this dispute in Oaxaca's favour, and annulled the 2011 decree that had created Belisario Domínguez.
