Was the industrial revolution mainly about the growth of manufacturing industry?

Some readers may think this question is like asking whether the Pope is a Catholic. The question is worth considering, however, because it raises some fairly common misconceptions about the industrial revolution (some of which I held until recently).

My main reason for reading about the industrial revolution has to do with my interest in human flourishing. The industrial revolution led to a massive, unprecedented and ongoing improvement in living standards, beginning in Britain and then spreading to other parts of the world. From that perspective, the industrial revolution tends to be associated with the advent of sustained economic growth.

However, Joel Mokyr suggests that the best available estimates indicate that growth in per capita income in Britain did not accelerate until the decades after 1830 - well after the beginning of the industrial revolution (‘The Enlightened Economy’, p 256). That makes sense if we define the industrial revolution in terms of the technological innovations which brought about a transformation in the way goods and services were produced in the British economy between 1760 and 1830. One reason why these innovations were not immediately reflected in higher per capita income growth was the rapid growth of population – the English population increased from 6.1 million to 13.1 million between 1760 and 1830 (p.257). Another reason was the initial concentration of major innovations in a relatively small, though rapidly growing, part of the British economy (p. 82).

Information from a table presented by Deirdre McCloskey is graphed below in order to provide some perspective on the contribution of different industries to productivity growth in Britain over the period from 1780 to 1860 (‘Bourgeois Dignity’, p.219).

Figure 1 shows the relatively rapid growth of productivity in some manufacturing industries as well as canals and railways.

Figure 2 shows that despite the more modest productivity growth rate in agriculture, the relatively large size of this sector means that over the period considered its contribution to overall productivity growth was comparable to that of the manufacturing industries with more rapid productivity growth.

So, was the industrial revolution mainly about the growth of manufacturing industry? Perhaps, if we define the industrial revolution so narrowly that it has to refer to the growth of manufacturing industry. If we do that, however, we need another term to describe the processes leading to the advent of economic growth in Britain. Joel Mokyr’s term, the industrial enlightenment, aptly describes the broader processes through which a social climate favourable to innovation was made possible by growing recognition that material progress could be achieved through advances in science and technology.

Mokyr puts the various phases of the industrial revolution in context as follows:

‘The Industrial Revolution was above all a beginning. It cannot be judged on its own grounds without considering what it led to. What is truly significant is not the wave of great inventions made in the years between 1765 and 1800, but the fact that this process did not subsequently fizzle out. Some societies, in Europe and Asia, had witnessed previous clusters of macroinventions, leading to substantial economic changes. ... The “classical” Industrial Revolution in the eighteenth was not an altogether novel phenomenon. In contrast, the second and third waves in the nineteenth century, which made continuous technological progress the centrepiece of sustainable economic growth, were something never before witnessed and that constituted a sea change in economic history like few other phenomena ever had’ (p. 83-4).
