Leader and Clerk Resources 3.1.1, which is currently in beta but should be released any day now, will give you access to a few basic reports on the site.
High councilors and stake auxiliary presidencies, including secretaries, can now access the following pages: Quarterly Report, Unit Statistics, and Key Indicators.

However, you won't have the same access as ward leaders – see the FAQ item quoted by eblood66 above.
Another reason for limiting access, besides what's mentioned in the FAQ, is to protect the Church from privacy concerns that in some places could become legal issues – which is especially important when dealing with youth and children.
