One of the significant outcomes of the "demographic trap" is explosive population growth. This is currently seen throughout Asia, Africa and Latin America, where death rates have dropped during the last half of the 20th century due to advanced health care. However, in subsequent decades most of those countries were unable to keep improving economic development to match their population's growth: by filling the education needs for more school age children; creating more jobs for the expanding workforce; and providing basic infrastructure and services, such as sewage, roads, bridges, water supplies, electricity, and stable food supplies.[1]
