Pinoy Big Brother Unlimited 2011

A total of fourteen housemates entered the House, thirteen official housemates plus a sub-official housemate acting as a "mole" in a task to become the fourteenth official housemate. That sub-official housemate was chosen by lottery from a pool of 30 "reserve housemates" (auditionees who were shortlisted for the show, but did not make the official cut). How the other 29 "reserve housemates" would be involved will be slowly revealed as the season progresses.

All thirteen official housemates plus the sub-official "mole" housemate entered the House on Day 1 (October 29, 2011). The ages indicated were the housemates' ages upon their entrance to the House.
