Answer:
The population of sub-Sahara Africa has grown from 186 million to 856 million people from 1950-2010. That’s about 11 million people a year for the past 60 years or approximately 670 million people in 60 years. By 2060, the population of sub-Sahara Africa could be as large as 2.7 billion people.
1) Most of the cities would look pretty small considering there was only one city in the 1900 that had over 3 million people.
2) Still, most of the cities would be small dots, but now their are a couple more cities with a large population because of the number change.
3) Almost all the cities increased their population over the years but very few decreased.
I think C but I'm not suuuuuper sure
