What are the demographic processes characteristic of the 19th century?

As everyone knows, in the 19th century, an industrial revolution and a rapid growth in industrial production took place. And what does it mean? If earlier people worked the land and she fed them, then in the new conditions people had to go to work at the plant and earn money. And this means that people had to move from village to city, and therefore there was a rapid process of urbanization of the population, as well as migration. In addition, the birth rate fell slightly, because it was more difficult to keep 4-5 children in these conditions.
