What demographic changes occurred during the Industrial Revolution?
There were two major demographic changes that occurred during the Industrial Revolution. One of them was caused in part by the Industrial Revolution, the other was not.
The change that was not caused by the Industrial Revolution was a general increase in population. As the link below tells us, the population of England and Wales (for example) was ten times bigger in 1850 than it was in 1800. As the population increased, it also became much more urbanized. Some of this was due to the Industrial Revolution as people moved from the country to the cities to work in the new factories. Again, the link below tell us that 10% of people in England and Wales lived in cities in 1800, but 50% did in 1850.
