DUE BEFORE LAB SESSION ON SEPT 16/17/18. Submit assignment to Digital Dropbox in Blackboard. Population below is in millions… 1,000 million = 1 billion The site below has a population clock which provides estimates of the current population. For example, when I checked the estimate last Friday Sept 6, it was 6,721,660,410. By the time you check it will be higher to reflect the increase in population during the past several days. Obviously this I just an estimate based on the current population growth trend. Current world population growth rate is about 1.14% per year The rate of growth peaked in 1963 when it stood at about 2.19% a year. Check the population clock at the above site and record the figure that you see for current population. Then use the current growth rate to estimate what the world population will be a year from now assuming that the growth rate per year is 1.14% Current world population __ 6,721,660,410 _ Q1a. Estimated population a year from now_ 6,721,660,410 + (.0114 x 6,721,660,410)=6,798,287,339 Q1b. Estimated population a year from now if the growth rate was 2.19% as in 1963 6,721,660,410+(.0214 x 6,721,660,410)=6,868,864,773 This is a simple prediction…we assume the current growth rate will continue into the future and our estimate is based on that belief.
