China and India have the largest populations of the BRICS countries, with approximately 1.4 billion inhabitants each. In contrast, the other three countries have a combined population of just over 0.4 billion people. Additionally, Russia, China, Brazil, and India rank among the seven largest countries in the world by area, whereas South Africa is 25th. Similarly, while the four original BRIC countries are among the 12 largest economies in the world in terms of GDP, whereas South Africa is outside of the top 40, and is only the third largest in Africa. Despite this, South Africa’s economy is considered the most diverse and advanced in Africa, and its position as one of the most politically stable countries in the region is viewed as the reason for its inclusion in the BRICS. Variations in size, human development, and political systems mean that the economic structures of these five countries also differ greatly. For example, all five countries have diversified economies, but China's is largely centered around its manufacturing industries, while Russia's is more dependent on its energy sector, and Brazil's on commodities.Development of BRICS economies
Since the term BRIC was first used 20 years ago, China has cemented its position as the strongest of the BRICS economies, becoming the second largest in the world behind the U.S. (in terms of GDP). China's economic boom began in the late-1970s, when it abandoned many isolationist policies, opened up to international trade, and introduced free market reforms. Rapid industrialization and urbanization of the world's largest workforce saw China become known as the "world's factory"; the influx of wealth and foreign investment saw significant improvement to living standards and opened up new, domestic markets. As China's manufacturing industries transition to the production of more technologically advanced goods, most forecasts suggest that it will become the world's largest economy by 2030.For Brazil, India, and South Africa, economic development has been a slower and more recent process, and has generally followed demographic development. In the 2010s, India overtook China as the world's fastest growing economy, and some estimates suggest it will also overtake the U.S. by the middle of the century. Along with China, India is the largest domestic market in the world, and its broad economic development is expected to mirror China's in many ways, although the role it plays internationally will differ. Brazil also saw significant growth in the early-2010s, before economic and political crises resulted in a recession; recovery from which has been slow.
For Russia, however, its economic development has differed greatly than the other four BRICS nations. During the late-20th century, Russia's predecessor, the Soviet Union, had been the world's second largest economy. However Soviet dissolution resulted in economic regression throughout the 1990s, until recovery in the 2000s when it was then considered a “developing” economy.
