Demographics
1.immigrate:to move permanently to a country other than one's native country
emigrate:to leave your country of origin to live permanently in another country
demography:study of population numbers, distribution, trends, and issues
birth rate:number of births per 1000 people
death rate:number of deaths per 1000 people
natural increase rate:difference between the birth rate and the death rte of a country
immigration rate:number of new Canadians who have immigrated here from another country per 1000 people of Canada's population
emigration rate:number of people per 1000 population in one year who emigrate
net migration rate:difference between people immigrating to a country and people emigration from the same country
population growth rate:measurement that combines both natural increase and net migration to calculate the overall growth of a country's population
doubling time:how long it would take for a country's population to double at the country's current rate of population growth
Rule of 70:in demographics, process whereby you divide 70 by the population growth rate to estimate how many years it will take for the country's population to double
dependency load:proportion of the population that is not in the workforce; total number of people 14 and under and +65 and over
population pyramid: graph that depicts population distribution by age and sex
2.a)The Rule of 70 is a process where you get the estimate of doubling time by diving 70 by the country's population growth rate
b)The Rule of 70 is really useful because it is a much easier way of knowing the doubling time without using difficult mathematical calculations or spreadsheets. You could see the trends and predict at what speed the country is going to majorly increase in population. and plan for the future.
c)i.about 140 years
ii.about 70 years
iii.about 47 years
iv.about 35 years
v.about 30 years
d) If you try to calculate the doubling time for Russia with it's negative growth rate of -0.4, you would get -175 years, which is not a suitable answer since it can't take a negative amount of years to double in population. So, the Rule of 70 cannot be applied for negative growth rates.
3.a) A population's dependency load is a part of a population that is unemployed and has to be supported by the ones working.
b)i.This would be a useful concept for a government planner because you could see whether you could increase/decrease taxes based on this number and plan out ahead if you see a trend. Like, for example, if you see an increase in the dependency load, they will have to send out more benefits and such.
ii.A president of a major bank will find this information useful because it will help him/her use it in order to design new advertisements for well-targeted audience.
c)I think that the ages are somewhat accurate, however, some people still work after the age of 65 to sustain themselves.
5.1.a) In 2020, I will be 22.
b)There will be a lot of people over the age of 70.
c)The least common age group will be from the age of 0 to 14.
d)The dependency load will be larger due to the high number of people over the age of 70.
5.2.Dependency Load Will Affect Me Because:
-I will be in the working age group, working to sustain myself, and the people younger and older than me
-if there is higher dependency load, that means I'll have to pay more taxes
