        SUBTOPIC-  Density of Population


            •  The number of the people living in a unit area of the earth’s surface is called population
               density.
            •  Population density is calculated by dividing the number of people by area and is usually
               expressed as the number of people per square kilometre.
            •  The average density of population in the whole world is 52 person per square km.
            •  South Central Asia has the highest density of population followed by East and South East
               Asia.
            •  Average density of population in India is 464 persons per sq km,(1202 people per mi²) as
               per 2020 statistics given by Govt Of India, which is second highest in the world after China.
            •  Population density of a place depends on a range of geographical and socio-economic
               factors.




        Factor Affecting Distribution of Population


            1.  Geographical Factors
                   1.  Topography: Most of the population resides in plain areas as it provides better
                       condition to live. People prefer to live on plains because these areas are suitable for
                       farming, manufacturing and service activities.
                   2.  Climate: People prefer to live in moderate climate and avoid very hot or very cold
                       climates.
                   3.  Soil:Areas with fertile soil are densely populated as the land there is suitable for
                       agriculture.
                   4.  Water: Easy availability of fresh water also makes an area habitable.
                   5.  Minerals:Areas which have more mineral resources present are more populated.




            2.  Social, Cultural and Economic Factors
                   1.  Social: Areas that have better housing, health and education facilities are more
                       populated.
                   2.  Cultural: Places like Vatican City or Jerusalem that have religious or cultural
                       significance also attract people.
                   3.  Economic: Politically stable country provides better living conditions to people
                       hence has more population. Industrial areas attract more people since they can
                       provide more employment opportunities. Osaka in Japan and Mumbai in India are
                       both densely populated areas.
