Where can we see the full range of jobs clients want by category?

I'd love see a periodic report that shows the break down of client jobs by language and gender/age. For example:

For January 2015:
200 jobs American English Female/mid age adult
10 jobs American English Female/young adult
150 jobs American English Female/older adult

If I'm of an age where I can still perform in all three categories, very naturally and authentically, but I can only pick two of them, I'd get more bang for my buck putting my samples in the middle-aged and older adult categories.

Likewise, if I'm British, with an Irish mum and a Welsh dad, and can do all three accents flawlessly, it would help me to know that VB has tons of RP jobs but many more requests for Irish reads than Welsh (or vice versa), when I'm picking my two language categories.

Will you make this report available to us, please? - Cat
