3. It is expressed in terms of the number of people per square kilometre of the land. A dense population would have more people per square kilometre compared to a sparse population.
4. For example, Singapore has a dense population of about 6 000 people per square kilometre, compared to Canada’s population density of 3 people per square kilometre. Total number of people Population density = Total land area
5.
6. Cities generally have high population densities while areas such as countrysides and deserts usually have low population densities.Countrysides usually have low population densities with few people per square kilometre. Cities have high population densities with high number of people per square kilometre.

9. Population distribution-The way in which people are spread out over an area of land is known as the population distribution. POPULATION DENSITY= Total number of people _______________________ Total land area
10. POPULATION DENSITY BY COUNTRY 1 Macau: 20,824.4 people per sqkm 2 Monaco: 16,486.7 people per sqkm 3 Hong Kong: 6,571.14 people per sqkm 4 Singapore: 5,539.77 people per sqkm 5 Gibraltar: 4,486.92 people per sqkm 6 Gaza Strip: 3,090.71 people per sqkm 7 Bermuda: 1,249.44 people per sqkm 8 Malta: 1,192.51 people per sqkm 9 Bahrain: 1,014.66 people per sqkm 10 Maldives: 1,000.73 people per sqkm

12. Population Pyramid what is population pyramid? A graphical tool that shows the proportion of the total population that is male or female in the horizontal axis and their age groups in the vertical axis
13. Concepts you should know Old:- those 60 and above Young:- Those between 0-14yrs Working populaion:- Between 15 yrs and 64 yrs Small proportion in the elderly age group Working population Proportion of youth and children
14. Population pyramid of countries with huge rate of population growth Narrow apex:- high death rate, poor medical fecility Broad base – high birth rate – high population growth
15. Countries with low rate of population growth Broader apex-better Medical Facility-aging population Narrower base- Low birth rate-low population growth
16. Figure 2: Relatively narrow base. Broader apex. Elderly population more than working population. Shows a developed economy Ageing population.
17. Inverted population pyramid In an inverted population pyramid, a huge number of elderly - supported by a smaller number of working people. The number of children continuously decreases. Less economically active persons in the future. And to make the situation even worse, the average age of workers likewise increases. Ex: Spain, Japan, Philippines.
18.
19. Low Rate of Population Growth Since 1980, the total fertility rate of Singapore has declined steadily and fallen below replacement rate. Singaporeans were getting married later, and more Singaporeans were remaining single; 30% of population were single in 2000 compared to 19% a decade earlier. As a result of this fertility decline, the Singapore population is aging at an alarming rate.
20. IMPLICATIONS AGEING POPULATION Smaller workforce : that can lead to slow economic growth. Higher taxes: burden on the working population. Defense: Lesser number of youths to join armed forces .
21. Actions -Encouraging marriage and childbearing -Incentives – Tax rebates ; child care subsidies ; child care leave ; flexible working hours for mothers ; affordable child care facilities and in-house child care facilities
