The intrastate regions (), and sometimes districts () are collections of municipalities in a Mexican state that are grouped together to support the administration of the state government and are not regulated by the Constitution of Mexico. The reasons for such a grouping include simplicity of administration and keeping statistics, politics, as well as geographic relationship (such as being part of a particular valley.)
Intrastate regions exist in the following 11 states:
Jalisco groups its 125 municipalities into 12 regions.
The State of Mexico groups its 125 municipalities into 20 regions, and they are numbered by Roman numerals.
Oaxaca groups its 570 municipalities into 30 districts, and then into 8 regions.
Veracruz groups its 212 municipalities into 10 regions.
Yucatán groups its 106 municipalities into 7 regions.
