World Bank uses the per capita income of the country as the principal criterion for classifying the countries as rich or poor. Per capita income is the average income of the people of a country in a given year.
This criterion of classification has number of limitations. They are
i. World Bank does not give equal importance to other factors such as literacy rates and general health standards of the people which plays an important role in defining the quality of life.
ii. The per capita income does not reflect information about the unequal distribution of income among the people
iii. Classification by income does not necessarily display the development status because economies in one group do not experience similar level of development.
Solution 5
The criterion used by World Bank is different from UNDP. It is because the World Bank measures the development based only on per capita income, while the UNDP’s Human Development Report measures the development in terms of per capita income, literacy rates and general health standards of the people.
Solution 6
To classify the countries only based on their total income would not be appropriate as different countries have different populations. Hence, we use averages. However, calculations based on average income have its own limitation because it does not tell us whether there is equal or unequal distribution of income in a country.
For example, there are two countries X and Y with five citizens each. Following table tells us about the income of these citizens.
Country
Citizen A (Monthly income in Rs)
Citizen B (Monthly income in Rs)
Citizen C (Monthly income in Rs)
Citizen D (Monthly income in Rs)
Average Income
X
20,000
2,000
1,000
1,000
Rs. 6,000
Y
2,000
3,000
3500
3500
Rs. 3000
In the above example, the average income of country X and Y is Rs 6000 and Rs 3,000 respectively. But we can see that while the average income of country X is the double of country Y, there is more disparity of income in country X than in country Y.
Solution 7
Yes, I agree that per capita income is not a useful criterion at all and should not be used to compare states. We can understand this fact with the help of the statistics of two states, Kerala and Punjab. The per capita income of Punjab (Rs 26,000) is higher than Kerala (Rs 22,800). However, the infant mortality rate (49) and literacy rate (70%) in Punjab are much lower than Kerala (infant mortality rate-11 and literacy rate-91%).
The above data clearly shows that per capita income alone cannot be used for measuring the development of a nation or a state.
Solution 8
While fire wood is the main source of energy in rural India, coal, petroleum and natural gas are used extensively for the production of energy. These sources are non-renewable resources i.e. they are exhaustible.
In about fifty years of time, we can hope to see various new renewable resources of energy being used on a much larger scale than they are used now. Solar energy, wind energy, geothermal energy, tidal energy and bio-gas made from the cow dung can be used extensively in future. Besides being renewable resources (non exhaustible), these are also environment friendly. a nation or a state.
Solution 9
Sustainable development means the judicious use of natural resources in such a way that they not only fulfill the needs of the present generation but also of the future generations. Sustainable development is required for the future growth and development of the countries. Development in an uncontrolled manner will not only lead to fast depletion of resources but will also result in stagnation of economies of the world. Sustainable development ensures stable and regular development of a country’s economy.
