Answer:
In the year 1750, only 4.8% of the world's population lived in settlements of more than 5,000 people, and in 1850, the number had risen to 9.5%.
Step-by-step explanation:
This evolution can be easily explained: by 1750, there were a few major cities in the world, but the economy fo the globe was predominantly rural, because farming was the activity that employed the majority of people.
By 1850, the world had not changed much in this sense, except for a few areas of the world: Northwestern Europe (England, Belgium, France, Germany), and the United States, where the industrial revolution was developing. Industry brought people from the countryside to the city to work in factories, and this led to the population boom in cities that we see today.
