We generate an average of one load/day. In one week we have:
2 loads of darks
1 load lights
1 load whites
1 load towels/dishcloths/napkins
2 loads bedding
I said 2-3 times/week because we often do multiple loads on the same day. I try to get caught up Fridays so we're not tied to the laundry weekends. We used to do it all on the weekends and it seemed we couldn't get out of the house for more than a couple of hours because there was always something needing to be washed, dried, or folded.
We all do laundry. I usually sort it and get it into the basket, the kids usually run it and move it to the dryer, DH or I fold, and everyone puts theirs away.
