Birth rate - death rate = x
X/1000 x 100 = x%
Whats stage 1 of population cycle
High fluctuating - undeveloped, total population low, high birth rates and high death rates eg Bangladesh
What is stage 2 of the population cycle
Early expanding - start of development, population rises, death rates begin to fall, improvements in healthcare , sanitation, food supply eg mali
