The table X below contains information on the population of four districts of country Z in the year 2016.
Use the information to answer the question which follows.
| District | Population (million) | Land Area (km\(^{2}\)) |
| A | 5.5 | 60,000 |
| 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
(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

- Presence of mineral resourtes
- Employment opportunities
- Availability of water
- Improved Port 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
