- 37. How popular? A countryโs population refers to the total number of people that are living there. China is the most populated country in the world. There are over 1.3 billion people living there. With a population of just over 11,000 , Tuvalu is one of the least populated countries in the world. What do you think the population of Singapore is?
- 44. Population structure MEDCs and LEDCs usually have differently structured populations due to differences in their birth and death rates. This shows the total population of males and females in different age ranges. The population structure of a country is usually drawn on a graph called a population pyramid . How would you describe the structure of this population pyramid?
Editor's Notes
- Worksheet: The worksheet A Growing Population accompanies this slide.
- Teacherโs notes: For an up-to-date list of the world population, please visit: http://www.census.gov/main/www/popclock.html. The most populated continent is Asia. In 1999, Asia accounted for 60% of the worldโs population. Asia was followed by Africa on 12.8% and Europe on 12.2%. (South America had 8.5%, North America 5.1% and Oceania 0.5%) Boardworks Ltd cannot take responsibility for external websites. Photo credit: ยฉ2008 http://www.sxc.hu/

- Teacherโs note: Having a high birth rate will result in more babies being born within the country. Having a low death rate will result in people staying alive for longer. If a countryโs birth rate rises or its death rate falls, there is a good chance that the population will increase. If a country has a birth rate that is rising and a death rate that is falling, the population will definitely increase. If more countries are developing medically, then their death rates will fall as their health care improves. There is also a chance that the birth rate will rise as the medical advances will allow ill babies to be kept alive for longer. Photo credit: ยฉ2008 http://www.sxc.hu/

- Teacherโs note: Typically, LEDCs have faster growing populations than MEDCs. This is because the birth rates of LEDCs tend to be so much higher than the death rates. This is due to many reasons: a lack of medical contraception, a tradition for large families, the need for children to support the family, etc. Worksheet: The worksheet MEDCs and LEDCs accompanies this slide.

- Teacherโs note: This population pyramid has quite a wide base. There is a very rapid narrowing of the sides of the pyramid and there is a very small percentage of the population who live to an old age. There appears to be a pronounced difference between the number of females and males surviving in this country. This could be due to ongoing wars. This is a population pyramid for an LEDC.
