The world’s population will go over seven billion this year, reveals a study of the French Institute of Demographic Studies, quoted by HotNews.ro. The biggest increases in population will be reported by the sub-Sahara Africa, the Arabian Peninsula and part of Asia. The six-billion threshold was surpassed in 1999 and it took 12 years to get to seven billion, but the study estimates that another 14 years will be needed to hit eight billion. The most populous nations are currently China, India, the US, Indonesia, Brazil, Pakistan and Nigeria. By 2050, India is expected to top the chart and China to come second.
