Donor movement tracking

Hello

I would like to report on donor movement in and out of memberships and up and down across levels, eg:

Normal 0 false false false EN-US X-NONE X-NONE

How many people gave in 2008 but not in 2009?

-       Which levels were they in?

-      What does the lost income = in dollars?

How many people gave more in 2009 than in 2008?

-       Which levels were they in?

-      What does this amount to in dollars?

How many people gave less in 2009 than in 2008?

-       Which levels were they in?

-      What does this = in dollars lost?

I know the NRR and Macro trends are involved in answering these questions but I'm not sure which reports to use.

Any would be greatly appreciated.

Willa
