japan has been facing issues regarding a decline in population. In 2012, Japan had a population of 127.52 million people. In 2021, it had a population of 125.3 million people. How much did Japan’s population decline between 2012 and 2021?

Answer 1

To find the decline in Japan's population between 2012 and 2021, we can subtract the population in 2021 from the population in 2012:

Population in 2012: 127.52 million
Population in 2021: 125.3 million

Decline = Population in 2012 - Population in 2021
Decline = 127.52 million - 125.3 million
Decline = 2.22 million

Japan's population declined by 2.22 million people between 2012 and 2021.

Answer 2

answer with a %

Answer 3

To calculate the percentage decline in Japan's population from 2012 to 2021, we can use the following formula:

\[ \text{Percentage Decline} = \left(\frac{\text{Decline}}{\text{Original Population}}\right) \times 100 \]

Where:

• Decline = 2.22 million
• Original Population (2012) = 127.52 million

Substituting the values:

\[ \text{Percentage Decline} = \left(\frac{2.22}{127.52}\right) \times 100 \approx 1.74% \]

Therefore, Japan's population declined by approximately 1.74% between 2012 and 2021.
