Use the table above to: (a) Calculate the (i) total population (ii) total land area (iii) population density (b) Explain four factors responsible for the distribution of world population. (c) Highlight three factors that cause increase in world population
Explanation
(a)(i) Total population of country X = 5.4 + 4.2 + 6.5 + 3.2 + 7.4 = 26,700,000 OR 26.7 million (ii) Total area of country X = 120,000 + 85,000 + 135,000 + 98,000 + 140,000 = 578,000km\(_2\) (iii) Population density for country X = Total Population Total population of X = 26,700,000; Total area of X = 578,000km\(_2\) (Area in km2) Population density of X = 26,700,000 578,000 = 46 persons/km\(_2\) (b) Factors responsible for the distribution of world population: (i) Relief (ii) Climate (iii) Soil (iv) Access:Dir. (v) Presence of minerals (vi) Water supply (viii) Industrialisation/job opportunities/H.E.P. presence (ix) Disease (x) Famine (xi) Religious persecution (xii) Political conflict (c) Factors of increase in world population: (a) Improved medical facilities (b) Improved hygiene and sanitation (c)Adequate food supply (d) Improved standard of living (e) Decline in death rate (f) Increase in birth rata (g) Social significance of children (h) Desire for male/female children (i) Religious belief (j) Early marriage
