We present a census of the disc population for UKIDSS selected brown dwarfs in the 5–10 Myr old Upper Scorpius OB association. For 116 objects originally identified in UKIDSS, the majority of them not studied in previous publications, we obtain photometry from the Wide-Field Infrared Survey Explorer data base. The resulting colour–magnitude and colour–colour plots clearly show two separate populat...
