Our CEO used a Demographic and Statistical Report in RE7 to easily pull giving by state. We have a national presence and the board wants to see how we are doing in each state or region. We often have to report on state-by-state giving for grants as well.
And an Address Processing option so orgs can select which address to use for the reports (living right near 2 state borders, many times a donor will have a business address in one state but home address in another; the business address marked Preferred but the home address should be the one used for the reports.
County would also be helpful for some orgs.
