In the United Kingdom, a survey of 2,000 parents and children from 2013 by Nielsen Book found that 36% of children read books for pleasure on a daily basis, 60% on a weekly basis, and 72% were read to by their parents at least once per week. Among British children, the most popular leisure activities were watching television (36%), reading (32%), social networking (20%), watching YouTube videos (17%) and playing games on mobile phones (16%). Between 2012 and 2013, children reported spending more time with video games, YouTube, and texting but less time reading (down eight percent). Among children between the ages of 11 and 17, the share of non-readers grew from 13% to 27% between 2012 and 2013, those who read once to thrice a month (occasional readers) dropped from 45% to 38%, those who read for no more than an average of 15 minutes per week (light readers) rose from 23% to 27%, those who read between 15 and 45 minutes per week (medium readers) declined from 23% to 17%, and those who read at least 45 minutes a week (heavy readers) grew slightly from 15% to 16%.
