El Salvador vs. Guatemala

El Salvador is the smallest and most densely populated country in Central America. It is well into its demographic transition, experiencing slower population growth, a decline in its number of youths, and the gradual aging of its population. The increased use of family planning has substantially lowered El Salvador's fertility rate, from approximately 6 children per woman in the 1970s to replacement level today. A 2008 national family planning survey showed that female sterilization remained the most common contraception method in El Salvador - its sterilization rate is among the highest in Latin America and the Caribbean - but that the use of injectable contraceptives is growing. Fertility differences between rich and poor and urban and rural women are narrowing.

Salvadorans fled during the 1979 to 1992 civil war mainly to the United States but also to Canada and to neighboring Mexico, Guatemala, Honduras, Nicaragua, and Costa Rica. Emigration to the United States increased again in the 1990s and 2000s as a result of deteriorating economic conditions, natural disasters (Hurricane Mitch in 1998 and earthquakes in 2001), and family reunification. At least 20% of El Salvador's population lives abroad. The remittances they send home account for close to 20% of GDP, are the second largest source of external income after exports, and have helped reduce poverty.

Guatemala is a predominantly poor country that struggles in several areas of health and development, including infant, child, and maternal mortality, malnutrition, literacy, and contraceptive awareness and use. The country's large indigenous population is disproportionately affected. Guatemala is the most populous country in Central America and has the highest fertility rate in Latin America. It also has the highest population growth rate in Latin America, which is likely to continue because of its large reproductive-age population and high birth rate. Almost half of Guatemala's population is under age 19, making it the youngest population in Latin America. Guatemala's total fertility rate has slowly declined during the last few decades due in part to limited government-funded health programs. However, the birth rate is still more close to three children per woman and is markedly higher among its rural and indigenous populations.

Guatemalans have a history of emigrating legally and illegally to Mexico, the United States, and Canada because of a lack of economic opportunity, political instability, and natural disasters. Emigration, primarily to the United States, escalated during the 1960 to 1996 civil war and accelerated after a peace agreement was signed. Thousands of Guatemalans who fled to Mexico returned after the war, but labor migration to southern Mexico continues.
