The survey data released by social TV startup Zeebox points to a generational divide over the use of Twitter.
Overall, 13 per cent of the UK sample said they used Twitter at least daily compared to 10 per cent in the US.
The age breakdown suggests that people between the ages of 16 and 34 are the heaviest users.
In the UK, 22 per cent of 16-24 year-olds reportedly use Twitter daily, together with the same number for those aged between 25 and 34. This compares to only 8 per cent of 35 to 44 year-olds and 7 per cent of 45 to 54 year-olds.
The stats for the US paint a similar picture, though Twitter use declines at an earlier age.
Some 20% of 16 to 24 year-old Americans use Twitter every day. This compares to 12 per cent of 35 to 44 year-olds and 5 per cent of 45 to 54 year-olds.
The latest Ofcom report also points to the higher use of Twitter among the 16 to 24 year-olds in the UK.
The use of Twitter might be specifically related to the growth of smartphones. Four in ten adults now own a smartphone in the UK, according to the Ofcom report.
What is clear is how the way we communicate is changing, fueled by social media, widespread connectivity and increasingly powerful mobile devices.
Zeebox published the results of UK and US survey on Google Docs for other to analyze the data.
