The statement is Supported.

During the 20th century, the human population increased from less than 2 billion to more than 6 billion. This information can be seen in the provided references, which show the growth of the human population over time. For example, Figure 24.8.3 clearly illustrates the exponential growth of the population, with the number reaching 7 billion by 2012.
