This list tracks and ranks the population of the top 10 largest cities and other urban places in Mexico by decade, as reported by each Mexican Population Census, starting with the 1921 Census.
This list generally refers only to the population of individual localities within their defined limits at the time of the indicated census.
Some of these places have since been annexed or merged into other cities, while others may have expanded their borders due to such consolidation.
[1] There is no information at locality level from the first three population censuses, completed in 1895, 1900, and 1910.
Tacubaya, a neighboring independent city in present's day Miguel Hidalgo borough, was among the Top 10 localities, along with the most developed commercial and industrial cities at that time.
