B
8.0
105,000
C
6.7
125,000
D
4.8
88,000
(a) calculate the; i. total population of country Z ii. total land area of country Z iii. population density of country Z (b) State four factors that are responsible for high population densities of countries. (c) Explain three advantages associated with countries of high population density
Explanation
(a)i. Total population of country Z (in millions): = 5.5 + 8.0+ 6.7+ 4.8 = 25 million (25,000,000) ii. Total land area of country Z (in Km\(^{2}\)): = 60,000+105,000+125,000+88,000 = 378,000 km\(^{2}\) iii. Population density of country Z = \(\frac{\text {Total population }}{\text {Land area}}\) = \(\frac{25,000,000}{378,000}\) = 66.1 persons per km\(^{2}\)
(b) Factors that are responsible for a high population density of a country: -Fertile soil - Favourable climate - Lack of family planning - Availability of infrastructure - Improved standard of living - Availability of social amenities - Good transportation network - Improved agricultural practices - Low death rate/mortality. - High birthrate - Educational facilities - Industrial concentration. - Presence of mineral resourtes - Employment opportunities - Availability of water - Improved Port facilities - Availability of medical facilities - Political stability or good governance - Commercial activities or trade (c) Advantages associated with countries of high population density: - Full utilization of resources - Population for defense - Large labor force - Increased tax level -Large market/demand - Export of manpower - Increased productivity - High planning - Ease of provision of social amenities - High investment opportunity - Quick dissemination of information/ideas - High planning - Social cohesion/togetherness - Respect in the committee of nations
