SECTION CXLVI.. National Income.--Its Statistical Importance.

NATIONAL INCOME.--ITS STATISTICAL IMPORTANCE.

Among the most important[146-1] but also the most difficult objects of statistics, that book-keeping of nations, is national income. In estimating it, we may take our starting point from the goods which are elements of income, or from the persons who receive them as income.[146-2]

In the former case the gross national income consists:

A. Of the raw material newly obtained in the country.

B. Of imports from foreign countries, including that which is secured by piracy, as war-booty, contributions, etc.

C. The increase of values which industry[146-3] and commerce add to the first two classes up to the time of their final consumption.

D. Services in the narrower sense and the produce (Nutzungen) of capital in use.

All these several elements, estimated at their average price in money, which supposes that all purchases, especially those under the head D, are made voluntarily[146-4] and at their natural price.

To find the national net income, we must deduct the following items:

A. All the material employed in production which yields no immediate satisfaction to any personal want.[146-5]

B. The exports which pay for the imports.

C. The wear and tear of productive capital and capital in use.

In the second case the net national income is to be calculated from the following items:

A. From the net income of all independent private businesses etc.[146-6]

B. From the net income of the state, of municipalities, corporations and institutions, derived from their own resources.

C. Under the former heads must be taken into the account such parts of property as have been immediately consumed and enjoyed.[146-7]

D. Interest on debt must be added only on the side of the creditor, and deducted from the income of the debtor; otherwise, error dupli. This does not apply to taxes or church dues because the subjects of a good state and members of a good church purchase thereby things which are really new and of at least equal value to the outlay. Besides, in both instances, it is necessary to calculate the number of men who live from the national income, the average amount of their indispensable wants, and the average price in money of the same, in order to determine the free national income by deducting the sum total of these average wants, estimated at this average price.[146-8] [146-9]

In France, about forty years ago, according to Chaptal, Doudeauville, Balbi and others, about 6,500,000,000 francs gross national income could be counted on. Schnitzler speaks of 7,000,000,000 francs (Creation de la Richesse en France, 1842, I, 392), after deduction made of the raw material of manufacture. According to Wolowski, Statistique de la Fr., 1847, it was more than 12,000,000,000 francs. M. Chevalier, Revue des deux Mondes, March 15, 1848, has it 10,000,000,000 at most. In these four estimates, only material products are taken into account. Ch. Dupin thinks the income per capita was, in 1730, = 108 francs; in 1780, = 169; in 1830, = 269. Cazeaux, Eléments, 163, estimated the net national income, in 1825, at 5,000,000,000 francs; Cochut, in 1861, at 16,000,000,000. (Revue des deux Mondes, XXXVII, 703.)

In Spain, Borrego, Nationalreichthum, etc. Spaniens, 1834, 33, estimated the income from agriculture at 2,284,000,000 francs; from industry, etc., 361,000,000; commerce, 124,000,000; from houses, 186,000,000; canals, streets etc., 8,500,000; personal services, 75,000,000; money in circulation (probably loaned capital), 85,000,000.

In the United States, in 1840, the national income was estimated at over $1,063,000,000; from agriculture, over $654,000,000; from manufactures, nearly $240,000,000; commerce, almost $80,000,000; mining, over $42,000,000; from lumber (Wäldern), almost $17,000,000; and from the fisheries, almost $12,000,000. The per capita amount of income was $62. It was largest in Rhode Island--$110; in Massachusetts it was $103; in Louisiana, $99; and in Iowa, smallest, $27; in Michigan, it was $33. Compare Tucker, Progress of the United States, 195 ff. The census of 1860 assumes the national wealth, slaves not included, at $14,183,000,000, that is $451 per capita, with a per capita annual income of $112. According to Czörnig, the gross income of Austria, from agriculture, the chase and fisheries, in 1861, was 2,119,000,000 florins; from mining, 41,000,000; from the industries, 1,200,000,000. In Prussia, the net national income, not including the revenue from state property, nor the income of the royal household, seems, from the returns of the income and class tax, to have been about 2,458,000,000 thalers, in 1874.
