Changes in the population density of MTxico City over time are presented in Table 2, which may be found on the following page. As the data presented in Table 2 indicate, the definition of the area that constitutes greater MTxico City has expanded over time. As time has passed, the area that defines MTxico City has extended further and further beyond the area that today is recognized as the Federal district.
Population density in greater MTxico City has remained between 14,000 and 14,877 persons per square kilometer since 1930. The important change related to population density that has occurred since 1930 is that this level of population density has steadily expanded to greater distances beyond the center of MTxico City.

The rate of population growth in the ZMCM has slowed since 1980. In part, the slowing rate of population growth is attributable to the laws of larger numbersùa steady annual increase in the number of people will reflect a lower rate of growth. Another reason fo
