The population would be about #308,385,845# people.

Use the formula for exponential growth, because each year the population increases from what it was the previous year.

#A = P(1+R)^n" "larr R# is the percentage increase

#A = 297,411,400(1+0.91/100)^4#

#A = 297,411,400(1.0091)^4#

#A = 308,385,845#
