There are a number of sources for online reports. The Toastmasters Dashboard is the first one I usually turn to for district, club, and member news. The Daily reports (link in the left side menu) takes you to other interesting reports like member educational awards, prospective clubs, club coaches, and dues payments.
Toastmasters.org Reports 2
District overviews, Area To-Do’s, Almost Distinguished, Clubs that need Coaches, and other very useful information for helping clubs (and districts) achieve Distinguished status.
George Marshall’s TmTools
A fantastic array of historical reports. George collects data from the Toastmasters Dashboard, stores it, and makes it easily searchable. I use this all the time.
