Legend information in mapbook

My question is in regards to information in the legend using mapbook. I have a point feature representing streetlights. For billing purposes they are categorized in a field called “BILLING” and a streetlight is given one of the following values; “PRIVATE NON-GOVERNMENT, PRIVATE-GOVERNMENT AND PUBLIC WORKS”. Each municipalty has an .mxd showing the amount of streetlights in that municipality. So in one municipality I might have 300 streetlights. Out of that 300, I can show the numbers of each of the values. However, I am not able to do it for each page. It just shows the same information on all the pages. Does map book have a way to break down the information I need to show that is unique to each grid within each municipality? Thanks for your help.

Fun--I did something very similar for an election map, supporting people walking, canvassing, neighborhoods--I had to create counts of voters by party affiliation on each sheet. The way I did this was to do a spatial join of my voters (your streetlights) to my map sheet index polygon feature class.  I just ran the spatial join three times--once where my voters had a definition query for democrats, another for republicans, and so on.  That provided a sheet by sheet count of each party's voters. From that you can do auto-text based on having your map sheet index layer in your map.
