Based on the information in the graph, what is the best conclusion to draw
Sever21 [200]

The correct answer is C. The birthrate is higher than the death rate.

Explanation

The graph is about the growth of the world population, this shows the population growth of the world, Asia, Africa, Europe, United States, Canada and Greenland, Mexico, Central America, Caribbean Islands, and South America, and Oceania (Australia and nearby islands in the Pacific). This graph covers the time from 1950 to 2050 divided into decades. In the specific case of Africa in 1950 it had a population of close to 300 million people. Subsequently, in 2010 the population of Africa was close to 1 billion people and the projection for the year 2050 is 2 billion people. According to this, it can be concluded that the birth rate is higher than the death rate because the population has a growth trend, which indicates that more people are born than die.
