How UK Government spun 136 people into 7m illegal file sharers

Citāts:
The 7m figure had actually been rounded up from an actual figure of 6.7m. That 6.7m was gleaned from a 2008 survey of 1,176 net-connected households, 11.6% of which admitted to having used file-sharing software - in other words, only 136 people.

It gets worse. That 11.6% of respondents who admitted to file sharing was adjusted upwards to 16.3% "to reflect the assumption that fewer people admit to file sharing than actually do it." The report's author told the BBC that the adjustment "wasn't just pulled out of thin air" but based on unspecified evidence.

The 6.7m figure was then calculated based on the estimated number of people with internet access in the UK. However, Jupiter research was working on the assumption that there were 40m people online in the UK in 2008, whereas the Government's own Office of National Statistics claimed there were only 33.9m people online during that year.
