The country's population decreased by about 2.4% during this time period.

Since we have given that

In 1990, the number of people = 167 million

In 2010, the number of people = 163 million

We need to find the percent decrease in the country's population during this time.

Percentage would be

New - Original x 100/original

= 163 - 167/167 x 100

= -4/167 x 100

=-2.39%

=-2.4%

Hence, the country's population decreased by about 2.4% during this time period.

Type of problem: Percentage decrease

Step 1: Find the difference between the two numbers

(Difference = original number - new number)

164,000,000 - 155,000,000 = 9,000,000

Step 2: Divide the difference by the original number

9,000,000 / 164,000,000 = 0.05487804878

Step 3: Multiply by 100 and round to find the percent

0.05487804878 x 100 = 5.48780487805

Round to one place = 5.5

Answer: 5.5% decrease in the population

Hope this helps!! :)
