1. (11+2+4+6+8+1+2+7)/(1+10+2+1+4)=227.28%
2.(6+8+9+11+2+4+6+8+1)/(1+2+6+8+9+11+2+4+6+8+1+2+7)=82.09%
3.for 2011 13/50=26%
  for 2012 2/67 = 2.98%
2011 has the higher share
4.for 2011 (3+3+1+1+10+2+1) / 50 = 42%
  for 2012 (6+9+8+11+2+4) / 67 = 59.70%

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
