Population change formula using raw numbers.
Population Change = (Births + Immigration) – (Death + Emigration)
What is crude birth rate
Annual number of live births per 1,000 population
What is crude death rate
Annual number of live deaths per 1,000 population
Population Change Formula
Population Change = (Birth Rate – Death Rate / 1,000) x 100
Doubling Time Formula
70 / growth rate %
What is the definition of total fertility rate (TFR)?
The average number of children a woman has during her reproductive years
What is the definition of Replacement-level fertility
The number of children a couple must bear to replace themselves
What factors affect the number of children a woman will have?

What factors affect death rates?
- Increased food supplies and distribution
- Better nutrition
- Improvements in medical and public health technology
- Safe water supplies to stop spread of diseases

What are the problems associated with rapid population decline?
- Threatens economic goals
- Labor shortages
- Less government revenues with fewer workers
- Less entrepreneurship
- New business formations
- Less likely to have new technology developments
- Increasing public deficits to fund higher pensions and health care costs
- Pensions may be cut
- Retirement age increases
What stage of the demographic transition is this?
Little population growth due to high infant mortality and harsh living conditions.
Stage 1: Preindustrial
What stage of the demographic transition is this?
Industrialization begins with high food production and improving health care., death rates drop, and birth rates remain high making the population grow rapidly.
Stage 2: Transitioning
What stage of the demographic transition is this?
Birth rate drops and approaches death rate due to better access to birth control, decline in infant mortality, increased job opportunities for women, and high cost of raising children
Stage 3: Industrial
