The DR is among the countries that classify as having a medium human development level, coming in the 95th place in the Human Development Index (HDI) in 2005. This is reported by the United Nations Development Program (UNPD). It says that life expectancy for Dominicans is 67.2 years, the adult literacy rate is 87.8%, enrolment in primary, secondary and higher education is 76% and the GNP per capita is US$6,823. AIDS is one of the health problems dealt with in the DR – 1.7% of the population between 15 and 49 years of age is living with the disease, rating third in Latin America after Honduras (1.8%) and Haiti (5.6%). Inequality is also manifested in other health indicators such as the infant mortality rate. The HDI is an indicator that covers three aspects of human welfare: income, education and health. Other Latin American countries, such as Brazil with 63rd place, precede the DR on the scale. It is followed by El Salvador (104) and Guatemala (117), respectively. Seven countries in the region are in the “high” range such as Argentina (34) and Cuba (52).
