Table question.

Use the following tabe to answer the question.
Population of Europe by Age Groups
    Population (in thousands)
    1950    1970    1995
Age 0-14    143,175    166,367    139,464
Age 15-64    359,162    421,432    487,110
Age 65+    44,981    68,642    101,338
Age 75+    14,553    22,762    38,139
Total    547,318    656,441    727,912

What was the percentage increase in the age 75+ population of Europe from 1970 to 1995?

Re: Table question.

Percentage increase is worked out by [(new value - old value)/old value] x 100%.

In this case, there were 22,762 thousand people aged 75+ in 1970 and 38,139 thousand in 1995.

So, putting those figures into the formula, we get [(38,139 - 22,762)/22,762]x100% = 67.6%, rounded to one decimal place.

Why did the vector cross the road?
It wanted to be normal.
