Which photograph has a high population density?
Population Population DensityDensity
= Total number of people per unit area of land
Calculation of Calculation of Population DensityPopulation Density
Total resident in 1997 = 3736700Total resident in 1997 = 3736700
Total land area = 647.8 sq kmTotal land area = 647.8 sq km
Pop density = 5768 Pop density = 5768 persons per sq kmpersons per sq km

Areas of high pop density Areas of high pop density (above 200 persons per sq (above 200 persons per sq km) are the major cities such km) are the major cities such as Kuala Lumpur, Melaka and as Kuala Lumpur, Melaka and Johor BahruJohor Bahru
Areas of moderate pop density Areas of moderate pop density (21 – 200 persons per sq km) (21 – 200 persons per sq km) are found on the coastal plain are found on the coastal plain on the east coaston the east coast
Areas of low pop density Areas of low pop density (below 21 persons per sq km) (below 21 persons per sq km)
ReliefRelief
Lowland areas/low reliefs are able to support a dense population
Development of settlements, transport, agriculture and industry
Central northern part is sparsely populated because it is mountainous
ClimateClimateWest coast more densely West coast more densely populated – sheltered from SW populated – sheltered from SW monsoon by Sumatramonsoon by Sumatra
More evenly distributed rainfall More evenly distributed rainfall and high temp (25 – 28°C) and high temp (25 – 28°C) favour cultivation of cropsfavour cultivation of crops
Sheltered from heavy rain Sheltered from heavy rain facilitates the growth of trade, facilitates the growth of trade, market towns and portsmarket towns and ports
East coast is exposed to NE East coast is exposed to NE monsoon as it faces South monsoon as it faces South China SeaChina Sea
Heavy and prolonged Heavy and prolonged downpour causes floods and downpour causes floods and inflict economic lossesinflict economic losses
SoilSoilSoil on the west coast is generally deep Soil on the west coast is generally deep and well-oxidised and is suitable for and well-oxidised and is suitable for growing cash crops such as rubber and growing cash crops such as rubber and oil palmoil palm
Presence of fertile alluvial soil which Presence of fertile alluvial soil which supports wet rice cultivationsupports wet rice cultivation
Hence, west coast able to support dense Hence, west coast able to support dense populationpopulation
East coast – swampy lowland East coast – swampy lowland
Mountains in central northern part – Mountains in central northern part – poor, thin, stony soilpoor, thin, stony soil
Minerals and Energy Minerals and Energy deposits deposits
Discovery of tin deposits in the west coast Discovery of tin deposits in the west coast (Kinta, Kelang Valley) attracted influx of (Kinta, Kelang Valley) attracted influx of Chinese immigrantsChinese immigrants
