Population Density<br /><ul><li>Population density is the number of people living in a unit area of land.
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.
For example, Singapore has a dense population of about 6 000 people per square kilometre, compared to Canada’s population density of </li></ul> 3 people per square kilometre.<br />Total number of people<br />Population density =<br />Total land area<br />
Population Density<br /><ul><li>People are not evenly distributed in a country and some regions are more crowded than others.
Cities generally have high population densities while areas such as countrysides and deserts usually have low population densities.</li></ul>Countrysides usually have low population densities with few people per square kilometre.<br />Cities have high population densities with high number of people per square kilometre.<br />
High Rate of Population Growth<br /><ul><li>Less developed countries with low levels of economic wealth and poor living conditions usually experience a high rate of population growth (e.g. countries found in Africa, South America and some parts of Asia).
A population pyramid can be used to show the pattern of population growth.</li></li></ul><li>
Population distribution-The way in which people are spread out over an area of land is known as the population distribution.<br />POPULATION DENSITY=<br /> Total number of people <br /> _______________________<br /> Total land area <br />

Population Pyramid<br />what is population pyramid?<br />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<br />
Concepts you should know<br />Old:- those 60 and above<br />Young:- Those between 0-14yrs<br />Working populaion:- Between 15 yrs and 64 yrs<br />Small proportion in the elderly age group<br />Working population<br />Proportion of youth and children<br />
Population pyramid of countries with huge rate of population growth<br />Narrow apex:- high death rate, poor medical fecility<br />Broad base – high birth rate – high population growth<br />
Countries with low rate of population growth<br />Broader apex-better Medical <br />Facility-aging population<br />Narrower base-<br />Low birth rate-low population growth<br />
Figure 2:<br />Relatively narrow base.<br />Broader apex.<br />Elderly population more than working population.<br />Shows a developed economy<br />Ageing population.<br />
Inverted population pyramid<br />In an inverted population pyramid, a huge number of elderly - supported by a smaller number of working people. <br /> The number of children continuously decreases. <br />Less economically active persons in the future. And to make the situation even worse, the average age of workers likewise increases.<br />Ex: Spain, Japan, Philippines.<br />
Low Rate of Population Growth<br /><ul><li>Mostly developed countries (Japan, UK) experience low rate of population growth</li></ul>low death rate low birth rate.<br />Factors that lead to Factors that lead to<br />low death rate? low birth rate ? <br />Higher standards of hygiene. Later marriages<br />Better nutrition. Fewer marriages<br />Better medical and health care . Preference for <br /> smaller families<br />
Low Rate of Population Growth<br />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.<br />
IMPLICATIONS<br />AGEING POPULATION<br /> Smaller workforce : that can lead to slow economic growth.<br />Higher taxes: burden on the working population.<br />Defense: Lesser number of youths to join armed forces .<br />
Actions <br /> -Encouraging marriage and childbearing<br /> -Incentives –<br /> Tax rebates ; child care subsidies ; child care leave ; flexible working hours for mothers ; affordable child care facilities and in-house child care facilities<br />

Low Rate of Population Growth<br />Actions to manage a low rate of population growth<br /><ul><li>Encouraging families to look after their elderlies- promoting by various programmes, tax subsidies.
There is also a need to encourage financial planning.
