Data (CSSA 2011 - q21)

Year / Unemployment:
1 - 1063000
2 - 1128000
3 - 1186000

Q: Calculate the rate of change on unemployment from year 2 to year 3 (show working):

My working was: Change = (1186000-1128000/1186000) x 100% = 4.89%

But in the answer it is 1128000/58000 = 5.1%

Can someone explain this to me??

Its the difference in unemployment between year 2 and 3 divided by the unemployment in year 2. Because it change from Year 2. What you did was put it all over Year 3 which is wrong.

(1186000-1128000/1128000) x 100 = (58000/1128000) x 100 = 5.1%

Okay, so the reason why you've gotten the wrong answer is because the denominator you have used in the question is incorrect. Whenever you do a rate of change type question, think back to your formulas for things like economic growth and inflation. It's always current year - previous year, all over the previous year.

So in this case, it'd be [(1186000 - 1128000)/1128000] x 100 = 5.1%

Hope that helps! :)

Not a problem!! Just think about it this way - if you're trying to see how it changed, you should be comparing back to what it started with, i.e. the previous year! :)
