Argentina vs. Paraguay

Argentina's population continues to grow but at a slower rate because of its steadily declining birth rate. Argentina's fertility decline began earlier than in the rest of Latin America, occurring most rapidly between the early 20th century and the 1950s, and then becoming more gradual. Life expectancy has been improving, most notably among the young and the poor. While the population under age 15 is shrinking, the youth cohort - ages 15-24 - is the largest in Argentina's history and will continue to bolster the working-age population. If this large working-age population is well-educated and gainfully employed, Argentina is likely to experience an economic boost and possibly higher per capita savings and investment. Although literacy and primary school enrollment are nearly universal, grade repetition is problematic and secondary school completion is low. Both of these issues vary widely by region and socioeconomic group.

Argentina has been primarily a country of immigration for most of its history, welcoming European immigrants (often providing needed low-skilled labor) after its independence in the 19th century and attracting especially large numbers from Spain and Italy. More than 7 million European immigrants are estimated to have arrived in Argentina between 1880 and 1930, when it adopted a more restrictive immigration policy. European immigration also began to wane in the 1930s because of the global depression. The inflow rebounded temporarily following WWII and resumed its decline in the 1950s when Argentina's military dictators tightened immigration rules and European economies rebounded. Regional migration increased, however, supplying low-skilled workers escaping economic and political instability in their home countries. As of 2015, immigrants made up almost 5% of Argentina's population, the largest share in South America. Migration from neighboring countries accounted for approximately 80% of Argentina's immigrant population in 2015.

The first waves of highly skilled Argentine emigrant workers headed mainly to the United States and Spain in the 1960s and 1970s, driven by economic decline and repressive military dictatorships. The 2008 European economic crisis drove the return migration of some Argentinean and other Latin American nationals, as well as the immigration of Europeans to South America, where Argentina was a key recipient. In 2015, Argentina received the highest number of legal migrants in Latin America and the Caribbean. The majority of its migrant inflow came from Paraguay and Bolivia.

Paraguay falls below the Latin American average in several socioeconomic categories, including immunization rates, potable water, sanitation, and secondary school enrollment, and has greater rates of income inequality and child and maternal mortality. Paraguay's poverty rate has declined in recent years but remains high, especially in rural areas, with more than a third of the population below the poverty line. However, the well-being of the poor in many regions has improved in terms of housing quality and access to clean water, telephone service, and electricity. The fertility rate continues to drop, declining sharply from an average 4.3 births per woman in the late 1990s to about 2 in 2013, as a result of the greater educational attainment of women, increased use of contraception, and a desire for smaller families among young women.

Paraguay is a country of emigration; it has not attracted large numbers of immigrants because of political instability, civil wars, years of dictatorship, and the greater appeal of neighboring countries. Paraguay first tried to encourage immigration in 1870 in order to rebound from the heavy death toll it suffered during the War of the Triple Alliance, but it received few European and Middle Eastern immigrants. In the 20th century, limited numbers of immigrants arrived from Lebanon, Japan, South Korea, and China, as well as Mennonites from Canada, Russia, and Mexico. Large flows of Brazilian immigrants have been arriving since the 1960s, mainly to work in agriculture. Paraguayans continue to emigrate to Argentina, Brazil, Uruguay, the United States, Italy, Spain, and France.
