The same procedures are often grouped together in this graph. Texas to North Carolina might be called “The Liposuction Belt” while Washington to Utah could be called “The Breast Implant Triangle”.
While there’s no clear reason why this might be, perhaps the higher than average level of obesity in The Liposuction Belt has something to do with it. And while it makes sense that the movie industry in California would result in lots of eager actresses searching for breast implants, it’s not clear why that would be the case in The Implant Belt. Maybe Montana is secretly the source for most of the world’s swimsuit models?
