The indigenous population of Mexico has in recent decades increased both in absolute numbers as-well as a percentage of the population. This is largely due to increased self-identification as indigenous, as-well as indigenous women having higher birth rates as compared to the Mexican average. Indigenous peoples are more likely to live in more rural areas, than the Mexican average, but many do reside in urban or suburban areas, particularly, in the central states of Mexico, Puebla, Tlaxcala, the Federal District and the Yucatán Peninsula.
