Particularly in rural areas, the Allende Government launched a campaign against illiteracy, while adult education programs expanded, together with educational opportunities for workers. From 1971 through to 1973, enrollments in kindergarten, primary, secondary, and postsecondary schools all increased. The Allende Government encouraged more doctors to begin their practices in rural and low-income urban areas, and built additional hospitals, maternity clinics, and especially neighborhood health centers that remained open longer hours to serve the poor. Improved sanitation and housing facilities for low-income neighborhoods also equalized health care benefits, while hospital councils and local health councils were established in neighborhood health centers as a means of democratizing the administration of health policies. These councils gave central government civil servants, local government officials, health service employees, and community workers the right to review budgetary decisions.
