Exactly. Also is the figure adjusted for inflation and if so, is it adjusted only for food inflation or inflation total over the years? Averages are also notoriously skewed. I would be far more interested in the mean. This is just a classic example of lying with statistics and is almost meaningless without further explanation of the underlying data.
My favorite example of the great statistical lie is to “prove” that human are becoming immortal. You see, it must be the case that we are becoming immortal because after about 150,000 years as a species, around 80% of all human beings that have ever lived are still alive.
Gallup has that data, the specific questions asked, etc. at the link in a downloadable Acrobat PDF.
