World Population To Reach 8.1b In 2025 11 hours ago Nigeria Hits 420m In 2050, Rivals China In 2100 THE world’s population, according to a recent United Nations’ forecast, will increase from its present 7.2 billion to 8.1 billion in 2025, with more than half of the growth coming from Africa. By 2050, it will reach 9.6 billion. That of Nigeria is expected to hit 440 million. India’s population is expected to surpass China’s by 2028 when each country will be about 1.45 billion, according to the report on World Population Prospects. While India’s population is forecast to grow to around 1.6 billion and then slowly decline to 1.5 billion in 2100, China’s is expected to start decreasing after 2030, possibly falling to 1.1 billion in 2100, it said. Among the fastest growing countries is Nigeria, whose population is expected to surpass the United State’s before the middle of the century and could start to rival China as the second most populous country in the world by the end of the century, according to the report. By 2050, Nigeria’s population is expected to reach more than 440 million people, compared to US’ 400 million. In 2100, the country is predicted to hover around 914 million. The report found that most countries with very high levels of fertility — more than five children per women — are on the UN’s list of least developed countries. Most are in Africa, but they also include Afghanistan and East Timor. But the average number of children per woman has swiftly declined in several large countries, including China, India, Indonesia, Iran, Brazil and South Africa, leading to a reduction in population growth rates in much of the developing world. In contrast, many European and eastern Asia countries have very low fertility levels. The population in developing regions is projected to increase from 5.9 billion in 2013 to 8.2 billion in 2050. In contrast, the population of developed countries is expected to remain largely unchanged during that period, at around 1.3 billion people. The report found that Africa’s population could increase from 1.1 billion today to 2.4 billion in 2050, and potentially to 4.2 billion by 2100. Even as the number of children in less developed regions is at all time high at 1.7 billion. In those regions, children under age 15 account for 26 percent of the population. In the poorest countries, children constitute 40 percent of their populations, posing huge challenges for providing education and employment. In wealthier regions, by contrast, children account for 16 percent of the population. In developed countries as a whole, the number of older people has already surpassed the number of children, and by 2050 the number of older people will be nearly twice the number of children. Low-fertility countries now include all of Europe except Iceland plus 19 countries in Asia, 17 in the Americas, two in Africa and one in Oceania. The populations of several countries are expected to decline by more than 15 percent by 2050, including Belarus, Bulgaria, Croatia, Cuba, Georgia, Latvia, Lithuania, Republic of Moldova, Romania, Russia Serbia, and Ukraine. Life expectancy at birth for the world as a whole rose from 47 years in 1950-55 to 69 years in 2005-2010 and is projected to reach 76 years in 2045-2050 and 82 years in 2095-2100.
