In total 55% of contestants to appear on the show have been below the age of 40.
The youngest competitor to date has been actor Louisa Lytton, who appeared on the show in 2006 when she was just 17 years old.
The record for the youngest person to make the Strictly final is held jointly by actors Christopher Parker (2004) and Matt Di Angelo (2007).
The oldest person to finish second on Strictly is TV presenter Susanna Reid, who reached the final in 2013.
Reid and Louise Redknapp are the only contestants in their 40s to have finished as runners-up in the competition.
