Against the widespread view that high wages and cheap coal drove industrialization, we find that industrialization was restricted to low wage areas, while energy availability (coal or water) had little impact Instead we find that industrialization can largely be explained by two factors related to the human capability of the labour force. Instead of being composed of landless labourers, successful industrializers had large numbers of small farms, which are associated with better nutrition and height. Secondly, industrializing counties had a high density of population relative to agricultural land, indicating extensive rural industrial activity: counties that were already reliant on small scale industry, with the technical and entrepreneurial skills this generated, experienced the strongest industrial growth. Looking at 1830s France we find that the strongest predictor of industrialization again is quality of workers shown by height of the population, although market access and availability of water power were also important.
