2.4 Flashcards
Demographic equation
Calculating the total population by adding and subtracting the total births and total death while also keeping the starting amount
Crude birth rate and equation
The average number of births per 1000 people
Births
————- • 1000
Population
What is a disadvantage of crude birth rate
It includes men so a population with more women will likely have a higher birth rate
What numbers are a Low birth rate
A CBR between 10 and 20 births per year per 1000 people
Transitional birth rate
A CBR between 20-30
Number for High birth rate
A CBR with more than 30 births
Total fertility rate or fertility rate
Average # of births per women from 15-49 years old
What does the fertility rate show?
The fertility rate of an area shows the level of replacement in order for the population to stabilize or grow
What effects fertility rates
Economic Developments, education, religion, government policies, gender roles
Crude death rates
And equation
of deaths per 1000 people death divided by population •1000
Disadvantages of CDR
An older population will have a higher CDR than those who don’t
What effects the CDR
Economic and wars
Infant mortality rate
of infants that die within the first year per 1000 Birthts
What does infant mortality help with showing?
The average living standards of a population (health care)
Rate of natural increase
Equation too
It is as a %
Difference between birth and death rates
(CDR-CBR) divided by 10 = RNI
This shows how fast the population is growing
