In another table, forty-seven industries are taken. These forty-seven industries comprised 29,800 establishments in 1900; five years later there were but 26,182. In 1900 the total capital invested in these industries was $1,005,400,000, and in 1905 it had increased to $1,339,500,000. In the same five years the number of wage-workers increased only from 618,000 to 749,000. Thus, in the group of larger industries and the group of smaller ones we find the same evidences of concentration: less establishments, larger capitals, and an increase of wage-workers not equal to the increase in capitalization.[102] In connection with these figures, the following table may be profitably studied, as showing the relative insignificance of the small producer in the total volume of manufacture. It will be seen that the two largest classes of establishments have only 24,163 establishments, 11.2 per cent of the total number. But they have $10,333,000,000, or 81.5 per cent of the total manufacturing capital, and employ 71.6 per cent of all wage-workers in manufacturing industries. It may be added that they turn out 79.3 per cent of the total product. Of the petty industries proper, those having a capital of less than $5000, it will be observed that they number 32.9 per cent of the total number of establishments, but employ only 1.3 per cent of the capital invested, and only 1.9 per cent of the wage-workers. It is clear, therefore, that our manufacturing industry in very highly concentrated, and that the petty industries are, despite their number, a very insignificant factor.
