Note 1: the variation in some nations due multiple studies with different results.

These polls are not all strictly measuring the same thing, the definitions are personal as to if dairy or an egg is a dis qualifier, nor do we know if people identify themselves as vegetarian yet still like me have a chicken breast or piece of salmon rarely.  What I did not include because it is convoluted information is these studies found in most every country there is a growing number who are inching towards vegetarianism, increasing the number of days they go without meat and reducing the serving size when they do eat meat.
The reasons people go vegetarian or vegan, 1) to improve their overall health, 2) environmental concerns,  3) “ natural approaches to wellness”, 4) food-safety concerns, 5) animal welfare, 6) weight loss, 7) weight maintenance.
A plant based diet with a wide variety of fruit, vegis, nuts, grains, olive or vegitable oils, spices, wine, combined with dialy exercise or 20 minutes walking and the elimination of all sugars except small amounts of molasses and honey) can in most people completely reverse; diabetes, correct cholesterol faster than statins, cut the risk of cancers of every kind, halt the progress of MS, reverse and correct heart disease, cut blood pressure, improve joint pain and slow arthritis, slow progression of dementia, altzhiemers, cut the incidence of bladder infections.  Why?  Meats carry into our bodies many pathogen and chemicals natural and man made that contribute to all those things listed above.  While plants carry natural antibiotics (blueberries and broccoli are the superhero's of this) nutrients and compounds of thousands of types that repair cells, even repair DNA, that stimulate the bodies ability to fight diseases, cancers, and to slow auto-immune actions like arthritis, where literally the body is attacking some part of it's self.  
I had triglycerides of 850, did not fill the prescription for statins, went plant based diet, numbers fell to 450 in 60 days and to 150 in less than a year.  We have been "almost" vegan for about 5 years.  In that time I bet we haven't eaten over 5 pounds of red meat and the last year we stopped almost all other meats eggs and dairy.  The myth is how can you get enough vitamins calcium and protein from plants.  The answer is you get enough of everything if you eat a variety, you may get less protein than before  but you will get enough, vegans do not die from lack of protein but of old age, while their friends die of strokes, cancer, heart attacks.  
I was going to make a list of all the things we ate yesterday, but the list is hugh, and the cost of a vegi diet, if you drop meat, sugar and diary it's about the same.
