Week 2 Flashcards
what is a population pyramid
a graphic presentation of the age and sex composition of the population
types of population pyramids
spike
wedge
barrel/beehive
spike population pyramid
high birth rate
high death rate
low growth rate
in equilibrium
wedge population pyramid
high birth rate
low death rate
high growth rate
in transition
barrel/ beehive population pyramids
low birth rate
low death rate
low growth rate
in equilibrium
demographic transition
a theory/model to explain shift from spike to barrel population pyramids
dependency ratio
the dependency ratio is a demographic measure of the ratio of the number of dependents to the total working-age population in a country or region
dependency ratio calculation
population aged 15-64 years
what is infant mortality rate
no. of live births
what does infant mortality rate show
measure of populations state of health
- general: food, sanitation, housing
- quality of health care

fertility rates
live births per 1000 women per year
- age specific fertility rates
- total period fertility rate
total period fertility rate
the average number of children that would be born to a woman over her lifetime
assumes that women
- have the same fertility as the population on average
- lives beyond the maximum age of giving birth
TPFR > 2.1
population increasing
factors associated with high fertility
poverty
extended family structure
pastoral/agrarian economy
religion
low socio-economic status
early marriage
pro-natalist policies
life expectancy
the number of years a baby born today can be expected to live IF it experienced the current age-specific mortality rates
