 Some municipalities or cities within municipalities are further divided into "delegaciones" or boroughs.However, unlike the boroughs of the Federal District, these are third-level administrative divisions; they have very limited autonomy and no elective representatives.Municipalities in central Mexico are usually very small in area and thus coextensive with cities (as is the case of Guadalajara, Puebla and León), whereas municipalities in northern and southeastern Mexico are much larger and usually contain more than one city or town that may not necessarily conform a single urban agglomeration (as is the case of Tijuana).
