Overcrowded land in the highlands was relieved when the rainforest to the east was subject to land reform. Cattle ranchers, loggers, and subsistence farmers migrated to the rain forest area. The population of the Lacandon was only one thousand people in 1950, but by the mid-1990s this had increased to 200 thousand. As of 2010, 78% lives in urban communities with 22% in rural communities.
