world population 2018

Sources - What is a population pyramid? China is the most populous country in the world with a population exceeding 1.4 billion. It took over 2 million years of human history for the world's population to reach 1 billion, and only 200 years more to reach 7 billion. 3,090,840. In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7,800,000,000 people as of March 2020 . World Population (total) Countries in the world by population; All people on 1 page (How many countries are there in the world?) Obviously, the UN data is based on estimates and can't be 100% accurate, so in all honesty nobody can possibly say with any degree of certainty on which day world population reached 7 billion (or any other exact number), let alone at what time. Others have estimated the number of human beings who have ever lived to be anywhere from 45 billion to 125 billion, with most estimates falling into the range of 90 to 110 billion humans. Over the 8,000-year period up to 1 A.D. it grew to 200 million (some estimate 300 million or even 600, suggesting how imprecise population estimates of early historical periods can be), with a growth rate of under 0.05% per year. 0.03 %.
