To add to the long list of things we lose as we age, according to Ofcom’s latest Market Communications Report, our digital confidence and understanding peaks during our teens before gradually dropping until our late 50s and then plunging from 60 and beyond.

The study measured the knowledge of communications technology of nearly 2,000 adults and 800 children and calculated their DQ, or digital quotient. The average UK adult scored 100.

According to the findings, six year olds have the same understanding of communications technology as 45 year olds, and more than 60% of people aged 55 and over had a below average DQ score.

The “millennium generation” of 14 and 15 year olds were found to be the most tech-savvy in the UK, earning an average score of 113. This generation’s habits are shaping technology’s future and how we communicate, favouring instant messaging and social networking over voice calls.

But being bested by children and teenagers hasn’t stopped us from voraciously consuming technology. In fact, the average UK adult spends more time using media than they do sleeping. Total use averaged over 11 hours every day in 2014, an increase of more than two hours since Ofcom’s last research in 2010.
