The table below shows the population distribution and land area of five states of a country B in the year 2010. Use the data to answer the following question

(a) Calculate the: (i) total population; (ii) total land area; (iii) population density of country B.

(b) Explain four factors that influence the distribution of world human population.

(c) Outline three factors that cause increase in world human population

Answer Details

(a)

1. Total population = 15,000,000 + 8,500,000 + 12,000,000 + 9,000,000 + 10,500,000 = 55,000,000
2. Total land area = 100,000 + 75,000 + 90,000 + 80,000 + 85,000 = 430,000 km²
3. Population density of country B = Total population / Total land area = 55,000,000 / 430,000 km² = 127.91 people/km²

(b) Four factors that influence the distribution of world human population are:

1. Natural resources - areas with abundant natural resources such as water, fertile land, and minerals tend to attract people.
2. Climate - people tend to live in areas with favorable climate conditions such as moderate temperatures and rainfall.
3. Economic opportunities - areas with better job prospects, higher wages, and business opportunities attract more people.
4. Social and political factors - social and political stability, access to education and healthcare, and cultural factors can also influence where people choose to live.

(c) Three factors that cause an increase in world human population are:

1. Fertility rates - the number of children born per woman has a significant impact on population growth. Higher fertility rates lead to population growth, while lower fertility rates can lead to population decline.
2. Increased life expectancy - as medical technology improves and access to healthcare increases, people are living longer. This can lead to an increase in the overall population.
3. Migration - as people move from one country or region to another, it can affect the population growth of both areas. Immigration can lead to an increase in the population of the receiving country, while emigration can lead to a decrease in the population of the sending country.
