Portuguese is with Spanish the fastest growing western language,
and, following estimates by UNESCO it is the language with the
higher potentiality of growth as an international communication
language in Africa (south) and South America. The Portuguese
speaking African countries are expected to have a combined
population of 83 million by 2050. After Brazil signed into the
economic market of Mercosul with other South America nations, such
as Argentina, Uruguay, and Paraguay, there has been an increase in
curiosity towards study of Portuguese language in those South
American countries. The demographic weight of Brazil in the
continent will continue to strengthen the presence of Portuguese
language in the region.
