I have mixed feelings about the Age and Gender chart. One one hand, I like how you combined these two demographics into one chart. On the other hand, age being usually Normally Distributed, do you need to show the difference in gender by age? Would it have been better to show total percentages for the Genders? The user might get a better idea how much the data is leaning towards one gender than the other if a total ratio was presented. In the end, I would say it would depend on the user and space available on the report.
