paragraph_text: Growth
  
  Greater Mexico City was the fastest growing metropolitan area in the country until the late 1980s. Since then, government policies have supported decentralization with the aim of reducing pollution in Greater Mexico City. While still growing, the annual rate of growth has decreased and is lower than that of Greater Guadalajara and Greater Monterrey.
  
  The net migration rate of Mexico City proper from 1995 to 2000 was negative, which implies that residents are moving to the suburbs of the metropolitan area, or to other states of Mexico. In addition, some inner suburbs are losing population to outer suburbs, indicating the continuing expansion of Greater Mexico City.
