Difficulties in Measurement of National Income Data
National Income data has many uses, because of which measurement of national income is a crucial activity of any economy. The computation of National Income is beset with lot of difficulties which have to be solved in order to arrive at a fairly accurate figure. In the underdeveloped countries, these difficulties are more prominent, making the very computation an extremely difficult task and the figure not too dependable.
There are some conceptual problems that crop up when we start measuring the national income of a country. Some are statistical in nature too. Some of these difficulties or problems involved in the measurement of national income are enumerated below:
1. National Income is calculated by adding price values of products. The price taken into account, though an average of certain years, remains an average and as such does not offer a correct figure.
2. The actual income is not disclosed by head of the family. It is concealed in order to evade tax payment.
3. Farmers, petty shop keepers, etc., in an underdeveloped country, do not maintain proper account. The figure of income given by them is arbitrary.
4. The farmers consume part of their product. The estimate of income given by them does not take into account that part of produce which is consumed by them.
5. Lot of confusion arises as regard how and what is to be included and what not in the measurement of National Income.
6. Statistical information of many sectors is not made available, like non-monetized transactions.
7. Unpaid services are not reckoned as national income.
8. The overwhelming majority of the small producers are illiterate and ignorant and they do not maintain any accounts of their productive activities.
9. In a country like India, where there are large regional diversities, languages, customs, etc. computation of national income is very difficult.
10. On the statistical side, the problem may be non-availability of data, inadequate data or it may be unreliable data.
11. The another formidable problem in the unorganized sector is that the village money-lenders and indigenous bankers maintain absolute secrecy of their transactions and give only wrong or underestimated figures.
12. The machinery for collecting statistical data may not be efficient, i.e. the investigators may be ill-equipped and quite unsuited to do the task.
13. The error of double counting is another formidable obstacle which should be avoided.
14. The major problem arises with regard to the treatment of income arising out of activities of the foreign firms in a country. Should that income to be added, to the country owning the firms or where it is located. However, it is credited to the parent concern.
The problem of calculation is very serious in underdeveloped countries. In the midst of difficulties, national income computations have been made more scientific and accurate in countries like India.
