Final answer:
Yes, both per-capita water use and total water use have increased in the last 100 years.
Step-by-step explanation:
According to the information provided, both per-capita water use and total water use have increased in the last 100 years.
Global total water use has steadily increased by a factor of six during the 20th century, while global population tripled. This increase in water demand is due to an improved standard of living and increased production of goods and energy.
In terms of per-capita water use, the data shows that we now use six times as much water as we did a hundred years ago. As population increases, the need for water continues to grow.
