blagie [28]

(Initial individuals + newborn individuals) - dead individuals = total individuals

Growth rate = (total individuals/initial individuals) * 100

Population growth rate = new percentage minus 100%

Calculations

(1000 + 500) - 200 = 1500 - 200 = 1300

Growth rate = (1300/ 1000) * 100

= 1.3 * 100

= 130%

Population growth rate = 130% - 100%

= 30% per year if it is uniform
