Rapid population growthRapid population
growth will lead to an increased demand for housing, which can in turn lead to housing shortage
Overall world population (represented by the beige bars) is increasing
The urban population of the world (represented by the blue line) is on the rise

‘Rural-urban migration refers to the movement of people from rural areas into cities to live and work.’
MigrationPeople migrate due to ‘push’ or ‘pull’
factorsPush factors: The undesirable qualities of the place they wish to leave
Pull factors: The attractive qualities of the place they would like to move toThe decision to migrate is often due to a
combination of both factors
Effects of MigrationPeople in rural areas often migrate to cities for job opportunities in search of a better life
Migrants do not always get jobs in citiesThere are a limited number of jobs for migrantsMigrants may lack the skills required for jobs
available in the cities Migrants who cannot obtain a source of income cannot afford housing
Cities cannot build enough houses for huge numbers of migrants quickly enough, causing them to settle in slums

‘Birth rate refers to the number of live births for every 1,000 people in a year.’
High birth ratesHigh birth rates and declining death rates result
in high rates of natural increaseNatural increase: The difference between birth rate and death rate in a yearBirth rates in cities may be high
Cities tend to have a large proportion of people in their 20s and 30s who are likely to start familiesThe increase in population may thus lead to
housing shortage

Competing land useLand has many uses – Residential ,
Commercial, Industrial, RecreationalLand dedicated for one use will not be available
for anotherExample: If a piece of land is occupied by a huge industrial park, that plot of land will not be available for housing development. Stiff competition for land can result in
insufficient land for housing
18
Limited land supplyThe amount of flat land is limited
Steep slopes are not ideal for housing development Cost of construction tends to be highLandslides can cause damage to buildings
Cities with very small land areas may have insufficient land for housing
There is a limit to how much land can be reclaimed from the seasCities with high population densities need to house more people in a small area
Large population size vs limited land areas
