In this training session for L2 DataMapping we'll cover ways you can manipulate universes to target more precisely and trim your data budget. We'll cover how to:
1. Merge two or more universes
2. Find overlapping voters by intersecting two universes
3. Subtract two or more universes
4. Expand a universe to include all voters in a household (especially helpful for mailing list creation)
5. Create a universe with just one voter per household
6. Filter by New Universe function
