For comparing countries, their income is considered to be one of the most important attributes. Countries with higher income are more developed than others with less income. This is based on the understanding that more income means more of all things that human beings need. Whatever people like, and should have, they will be able to get with greater income. So, greater income itself is considered to be one important goal. Now, what is the income of a country? Intuitively, the income of the country is the income of all the residents of the country. This gives us the total income of the country. However, for comparison between countries, total income is not such a useful measure. Since, countries have different populations, comparing total income will not tell us what an average person is likely to earn. Are people in one country better off than others in a different country? Hence, we compare the average income which is the total income of the country divided by its total population. The average income is also called per capita income. In World Development Reports, brought out by the World Bank this criterion is used in classifying countries. |

The rich countries, excluding countries of Middle East and certain other small countries are generally called developed countries. |
