As of 2021, the estimated population of the tropics is approximately 4.6 billion people, which accounts for about 60% of the world's total population. The majority of the tropical population is concentrated in South and Southeast Asia, with countries like India, Indonesia, and Bangladesh having large populations. Other regions with significant tropical populations include sub-Saharan Africa, Latin America, and the Caribbean.
Tropical populations are often characterized by certain socio-economic challenges, including poverty, inequality, and limited access to education and healthcare. However, the tropics are also home to some of the world's most vibrant and biodiverse ecosystems, and the people living in these regions have developed rich and diverse cultural traditions.
