The line graph illustrates the variation in the size of population, birth rate, and death rate, measured in millions, over a period of 300 years from 1700 to 2000. The three lines demostrate the population size, birth rate, and death rate.
Evidently, the population density was just 2 millions in the beginning, which steadily rose to 10 millions in 1750, before reaching a platuea 1800. The population then rocketed from 10 millions to 50 millions by the end of 2000, with a slight bent in the trajectory in 1900, when the census reported 35 millions.
As can be seen, the birth rate was always greater than the death rate, but with an almost identical fluctuations. The natality at the beginning of the data was 30 millions, which constantly stepped up until 40 millions in 1750, levelled off for a half- century, before it plunged to stabilize at 32 millions. It plummeted a second time reaching as low as 20 millions efore escalating to 34 millions in 2000.
Similarly, the fatality showed fluctuations similar to the birth toll. The death toll initiated at 27 millions in 1700, gradually increased to 36 millions and stablized until 1800, before the plunge to 26 millions. The death rate slupmed a second time to 20 millions before it flattened out in 1950 till 2000.
All in all, the data indicates that the population size might increase in the future as the birth rate starting increasing, diverging from the parallel trend of the death rate. The society might have to face the problem of overpopulation in the near future if the natality is not controlled in time.
