What is generation time?
The age that females reproduce
What is stage 2 in the demographic transition?

Stage 1 or 2
What stage would a fully developed country be in?
Stage 4 or 5
What is stage 4 in demographic transition?
Both birth and death rates are low

What is the growth rate equation?
Birth rate - death rates/1000 multiplied by 100
Birth rate: 14.4
Death rate: 8.5
What is the growth rate?
0.59
How would you determine what type of stage a country would be in?
Looking at their birth and death rates in the years shown
What stage would a growth rate of 0.59 be in?
Stage 4
What would a medium growth rate look like on a graph?
The lines for each generation would be around the same length
