We all know that numbers can be skewed a little for all kinds of reasons, however, it's worth looking at the survey based on research into Facebook. If you use FB for marketing you ought to read this.

If you look at the shape of the bar graph in the linked article (the last pair of graphs, Male and Female), you can see how much of it levels out if you simply shave the top off the "18" bars and apply it to the top of the 16s and 17s.

:: idly thinking how much the overall curve resembles the shape of a natural spectrum, which needs to be handled and interpreted very differently from a bell or sine curve ::
