Mexico's population is increasing rapidly, as a result of a traditionally high birth rate and a sharply reduced death rate. More than half of Mexico's population is under 25 years of age. Since the early 1950's, improved living conditions and expanded health services have greatly reduced the death rate in the country. The relatively young population and its high rate of growth have placed tremendous pressure on such services as education, health care, and social security. The strain on basic services is especially serious in urban centers.
Many cities lack adequate housing, clean drinking water, and public transportation.
Since 1970, the most rapid population growth has occurred in the states of Mexico, Morelos, Campeche, and Quintana Roo. The high rate of population growth has contributed to a shortage of jobs in Mexico. Since the 1980's, far more people have entered the labor force than have retired, while the economy has generally failed to create enough jobs. This situation has led to a high rate of unemployment. It has also stimulated increasing migration of Mexicans to the United States.
