I'm trying to fit this table to the width of the page, however, whenever I try to change the header width with the command {p{}} it doesn't adjust the width of the three main headers Population, Associations and Gymnasts.

Is there any way to adjust the table width so that it fits the page (it wouldn't be a tragedy if it exceeds the text width, but it should be fully visible)?
Furthermore, how can I increase the margin of the headers in the second row to the top (at present the headers are to close to the top \hline)?
Rfor the first column but then over-ridden that specification with a\multicolumnentry in every cell? That is likely to confuse tabulary quite a bit... – David Carlisle Jan 5 '15 at 22:12! Undefined control sequence. l.40 \captionsetup– David Carlisle Jan 5 '15 at 22:43
