Correct Answer: Option
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
