Packing = crowd together; cracking = split apart; redistricting = normal redraw.
Redrawing districts is normal after a census; gerrymandering is the unfair version done for party advantage. The difference is intent and fairness, not the act of redrawing itself. Watch for oddly shaped districts as a red flag.
