KQ1: Where is the worlds population distributed?

LO1. Define Population, Demography, and the key demographic indicators

Population- refers to the size and distribution of the Earth’s human population

Demography- a social science which entails the statistical study of human populations

In class we discussed mortality rates and how they can be used to find out population count and the stats that are associated with it.  We also learned how to use crude birth and crude death rates to find population increase/decrease.  

IMR- Infant mortality rate (0-1 years old)

CMR- Child mortality rate (0-5 years old)

Demographic Collapse- When the population suddenly plummets

We also talked about how we find out stats like population change

Rate of Natural Increase (RNI): a statistic that expressed a country or region’s annual growth rate; expressed as a percentage

• Made up of crude birthrate. (…/1000)
• Gives us # of births
• Made up of crude death rate (…/1000)
• Gives us # of deaths
• CB-CD= RNI
• To calculate the RNI, demographers subtract the death rate (number of deaths per 1,000 people/year) from the birth rate (number of birth per 1,000 people/year) and convert the answer to a percentage.
