Population Growth General Reasons
Sex ratio
Age structure

How a populations age affects the growth- Japan- old people
Life expectancy- Genes
Infant and child mortality
Fertility rate
Population pyramids
y- axis- age groups
X-axis- percentage
divided by gender
Youthful- like a pyramid
Ageing- Round in the middle
Aged- Opposite pyramid
Better if its "round in the middle", few young dependants, moderate level and life expectancy for older dependants
Natural disaster
War
Political Fear

Education
Higher wages/salaries

International migration- Different countries
