To get industrialization you need a surplus of labour and a food surplus too.

So one part is relatively high yield farms without requiring everyone in agriculture. Wheat has a lower caloric yield per acre then potatoes.

Another part is healthier cities. Things like sewers for instance. Cities are concentrated humanity, as such they increase the rates of both positive and negative aspects. City people walk and talk faster, have more patents per capita, more crime and more disease. Cities used to rely on immigration from the countryside to keep the population pools up. Simple infrastructure such as clean water and sewers is one of the reasons some cities out preformed their neighbors.
