Subject: Percentages increases/ decreases over 100% Name: Toya Who are you: Other I have some statistics from year to year based on drug seizures.(units= lbs) e.g. in 2005 123lbs seized in 2006 1518lbs seized. now i worked out the percentage increase as to be in the thousands which from looking at the figures is correct however i don't want to say 1000% increase. using another formula current- previous *100 I got 92%. what exactly does this 92% represent and how can i use this number when presenting my answers instead of using 1000 + % current Toya, The number of pounds seized increased from 123 to 1518 so the percentage increase is  (1518 - 123)/123 100 = 1134% I assume this is what you calculated also. On the other hand  (1518 - 123)/1518 100 = 92% so you might say "92% of the weight of this year's seizures is an increase over last year." I would however not use this statement as I would expect the question "Do you mean there was a 92% increase over last year?" The answer of course is "No, there was an 1134% increase over last year." If you want to report the increase in weight of the drugs seized as a percentage increase then you need to use this number, a 1134% increase. You could say that there is more than a ten-fold increase if that sounds better to you. Another option is to report the number of seizures and the percentage increase in the number of seizures rather than use weight. A variable other than weight might be more meaningful, especially if the substantial increase in weight is a consequence of a few large seizures. Stephen and Penny
