Answer
$$70 million$$
Work Step by Step
1. Look on the x-axis and find the year 2030.
2. Find the point at which the red line intersects with the line above 2030, and find the y value for that point.
3. Since, the y value is 70 and the unit of the y-axis is millions of people, the population in the year 2030 would be 70 million.
