At 592,800 square kilometres (228,900 sq mi), Madagascar is the world's 47th-largest country and the fourth-largest island. The country lies mostly between latitudes 12°S and 26°S, and longitudes 43°E and 51°E. The prehistoric breakup of the Gondwana supercontinent separated the Madagascar-Antarctica-India landmass from the Africa-South America landmass around 135 million years ago. Madagascar later split from India around 88 million years ago, allowing plants and animals on the island to evolve in complete isolation.
What are the poorest countries in the world? The rankings below were published in Wikipedia from International Monetary Fund’s 2011 gross domestic product per capita (GDP per capita) report and reflecting the countries with the lowest purchasing power parity (PPP). Since 1970, there has been encouraging news emerging from developing countries. According to the UN’s 2010 Human Development Report, life expectancy in developing countries has increased from 59 years in 1970 to 70 years in 2010. School enrolment climbed from 55% to 70% of all primary and secondary school-age children. Also, in the last forty years, per capita GDP doubled to more than ten thousand U.S. dollars. Poor countries are catching up with the wealthier countries, but not all countries are making fast progress. For example, some countries in Sub-Sahara Africa have little or no progress, largely due to the HIV epidemic and civil wars.
