Show People ot the World The present population of the world is approximately 1,900,000,000. Estimates of world population before 18S0 are not very trustworthy. Sir George Knibbs, however, considers that Michelot's estimate of 1,00!),-000,000 1,00!),-000,000 for 1S4I5 is as well founded a guess as cuu oe maue. vcepiing this estimate, it can he calculated that between 1S4S and 1914 the average aver-age annual increase of the world population was .7 per cent. It was, in other words, increasing at a rate which would double the population in less than 100 years. |
