continent.
How and why are there variations between the population structures of countries?
Why is global population changing?

Exam Qs
a. Describe the distribution of countries with the lowest rates of natural increase versus those with the highest rates of natural increase. (4)
b. Identify and compare two countries : one with low and one with high rates of natural increase. Use comparisons such as MEDC, LEDC and other development indicators to suggest why these differences exist. (6)

Hint…
Help!
Distribution just means pattern : so identify a pattern of countries and their populations. Natural increase is whether a population is growing or declining
(based on birth rate – death rate).
a. The countries with the lowest natural increase rates are found mostly in………………………….whereas countries with highest natural increase are found in…………………………. . For example, on average the continent / countries of …………………………………… (pick an area) have highest increase, whereas the countries / continents of ………………………………. have lowest increase.
b. One country that has high natural increase rates is …………………………. (pick a country from the map), the percentage increase is …………………..% One country with low natural increase is ……………………………… at ……..% The first is an LEDC because…………………………………which means natural increase will be higher because…………………………….. . Whereas the second country is an MEDC because…………………………………………so therefore natural increase is low due to………………………. Consider:
Development indicators like birth rate, death rate, literacy, infant mortality, access to doctors.Access / education on contraception and birth control.
Patterns of work, e.g. women in work, education for women, cultural differences.

Projected population
2050
UK 63,212,800 13 9 +4 79,555,900
China 1,350,378,000 12 7 +5 1,310,651,000
+10 more countries…
China: why a natural INCREASE in population today, but a DECREASE in population by 2050?
Task:1. Access the population reference bureau website.2. Complete your table of data, ensuring to choose a balanced mix of LEDC’s and MEDC’s.3. Plot each country on a world map and shade to show natural increase or decrease.

For example….
Population change vs Consumption
Is there a relationship between rates of population change and levels of consumption?
Explain your response using both MEDC and LEDC examples, and include links to
development indicators in your answer.
