The world has reached somewhat worrying demographic milestone. U.S. Census Bureau said on Thursday that population of our planet has surpassed 8 billion. spokesperson said the bureau estimated that global population exceeded 8 billion on 26th of September. However, he said this was very rough guess and the precise day could be month or two either side of this date. The Bureau declared that the world population would continue to grow at steady rate. It has grown from 6 billion to 8 billion in the past two decades. number of Earth's inhabitants had doubled between 1960 and 2000. The rate of growth is slowing as birth rates are falling in many nations.
Census Bureau attributed slowdown in population growth to trends of longer lifespans and lower fertility rates. However, it forecast that population would reach 10.2 billion in 2060. It said: " world population is projected to keep growing despite declining fertility rates. In fact, we estimate number of infants already peaked in 2017. Instead, population growth in future will come from larger groups of people at adult ages." It added: "Population growth is result of fertility, mortality, migration and share of the population at certain ages.…Nearly three quarters (74 per cent) of earth's population reside in countries where fertility is around or below replacement level."
