Describe the ratio of the small scale industries?

Formed only a small segment of the economy. Most of them – about 67 per cent in 1911 – were located in Bengal and Bombay. Over the rest of the country, small-scale production continued to predominate. Only a small proportion of the total industrial labour force worked in registered factories: 5 per cent in 1911 and 10 per cent in 1931. The rest worked in small workshops and household units, often located in alleys and bylanes, invisible to the passer-by. In fact, in some instances, handicrafts production actually expanded in the twentieth century. This is true even in the case of the handloom sector that we have discussed. While cheap machine-made thread wiped out the spinning industry in the nineteenth century, the weavers survived, despite problems. In the twentieth century, handloom cloth production expanded steadily: almost trebling between 1900 and 1940.
