since the majority of population n sindh is urban, even if the majority of crimes were urban I doubt it will leapfrog to #2 or #1 position, but as I noted earlier, even one of these barbaric crimes pepetrated by the worst animals of our society is too many. However if you want to have an assessment for statistical curiosity sake, please go ahead.
oh and in the interim I did find literacy rates for different provinces
here is a link

again across the board pretty pathetic and nothing to be gleeful about for any province, but it shows that some areas are indeed worse than others e.g. FATA is way below Islamabad etc. and NWFP is below Punjab when it comes to education in most categories for women
