Employment Projections
Job                      Number of People (2002)          Projection (2012)          Percent Change
Nursing Aides               1,375,000                             1,718,000                      25
Customer Service         1,894,000                             2,354,000                      24

(1,718,000 - 1,375,000) / 1,375,000 = 343,000 / 1,375,000 = 0.249 or 0.25 or 25%
(2,354,000 - 1,894,000) / 1,894,000 = 460,000 / 1,894,000 = 0.242 or 0.24 or 24%

The base number is the number of people in 2002. There is a higher percent change in number for nursing aides despite having lesser people added because its base number is lower than those in customer service.
