Hi,
You can find the man to women ratio by creating a calculative field and write code as
DIV([Man],[Women]) OR [Man] / [Women] , here [Man] and [Women] are the fields.
Religion | Ratio
----------------------------------
hindu | 2.034897
Muslim | 1.32176
Put the religion on row shelf and the ratio on column shelf then, the ration will be seen for each religion. (like above)
Hope this helps you.
