Latin America is the region of the Americas where Romance languages like Spanish and Portuguese are primarily spoken. Infrastructure and levels of development vary significantly across Latin American countries. Many countries still face challenges of poverty and are considered developing. Economic indicators like GDP, GNP, and per capita income are used to measure and compare levels of development between developing, transition, and developed nations. The geography of Latin America is diverse, containing rainforests, isthmuses, mountainous regions, and deserts. International agreements and trade blocs have aimed to increase economic integration and development across the Americas.
