Cosmetic Procedure Statistics
Ever wonder who in the mall has had a cosmetic procedure performed on them? Well it may be more people than you think! In 2003 alone, there were over 8.3 million surgical and nonsurgical cosmetic procedure performed, according to the most comprehensive survey to date of U.S. physicians and surgeons by the American Society for Aesthetic Plastic Surgery (ASAPS). The following statistics and more may be found at http://www.cosmeticplasticsurgerystatistics.com/statistics.html. Surgical procedures represented 22 percent of the total, and nonsurgical procedures were 78 percent of the total. There was a 20% increase in the number of cosmetic procedures performed from 2002-2003. Surgical procedures increased by 12 percent, and nonsurgical procedures increased by 22 percent. A whopping surprise was the fact that there has been a 293% increase in the number of cosmetic procedures performed since 1997. An increase of 87% for surgical procedures, and a sky high increase of 471% for nonsurgical procedures. The top five surgical cosmetic procedures in 2003 were: liposuction (384,626, up 3 percent from 2002); breast augmentation (280,401, up 12 percent); eyelid surgery (267,627, up 17 percent); rhinoplasty (172,420, up 10 percent); and breast reduction (147,173, up 17 percent). The top five nonsurgical cosmetic procedures in 2003 were: Botox injection (2,272,080, up 37 percent from 2002); laser hair removal (923,200, up 25 percent); microdermabrasion (858,312, down 17 percent); chemical peel (722,248, up 46 percent); and collagen injection (620,476, down 21 percent). An astonishing 7.2 million cosmetic procedures were conducted on women, which included the top five procedures: liposuction, breast augmentation, eyelid surgery, breast reduction and rhinoplasty. Men tipped the scales next with almost 1.1 million cosmetic procedures, which included: liposuction, rhinoplasty, eyelid surgery, breast reduction to treat enlarged male breasts, and hair transplantation. I was surprised by how many people in the United States were going through all this trouble. Im sure shows such as The Swan, and makeover shows are helping Doctors increase their profit further.

Margin of error in this doesn't refer to mistakes in performing a medical procedure. Remember, this information comes from a survey. We're trying to make inferences about the population from the survey sample.
The information tells you that there were 8.3 million surgical and nonsurgical cosmetic procedures performed in 2003 with are margin of error +/- 3.92% at a 95% confindence interval. The 8.3 million is, in a sense, a best guess.
The confidence interval is saying that there is 95% chance that the true number of procedures is +/- 3.92 percent of 8.3. So the most likely range is from 7.97m to 8.62m procedures.
Another way to get your head around this: What is the population of Great Britain? Instead of giving me a number give me a range so that you're 90% confident that the number is within this range. Now, you could say 1 million to 500 million people. The population of GB is surely within this range, but you'd give this range with 100% percent accuracy. Likewise, you could say 55 - 56 million, and your likely confidence interval for this range would probably be quite small (1 or 2 percent) unless you knew the that the population was 55.5 million.
For an interesting application, try the How well do you know things that you don't really know?.
We'll do more on confidence intervals at some point in the course.
