Q1
2012= 41 people
2011= 18 people
Increse
% different = 41/18 x 100% = 227.78%

Q2
age 34 - 54 = 55
people in 2012 = 67
55/67 x 100% = 82.09%

Q3
2011 = 13/50 x 100% = 26%
2012 = 2/67 x 100% = 2.99%
2011 higher share

Q4
2011 = 21/50 x 100% = 42%
2012 = 40/67 x 100% = 59.70%
2011 lower share

应该是这样吧
