What was the age 75 + population of Europe in 1995?
:
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

------------------------------

Read that right off the chart.  It's the number I marked 
in red above.

What was the percentage increase in the age 75 + population 
of Europe from 1970 to 1995?
a)67.6%
b)63.4%
c)68.9%
d)65.1%

It went from 22,762 in 1970 to  38,139 in 1995,

                  new - old
Percent change = ------------ × 100% 
                     old

                  38139 - 22762
Percent change = --------------- × 100% = 67.55557508%
                      22762

which rounds to choice (a).
