Several years ago The Daily Mail (and others) reported there were 4 million cameras in the UK - now they are halving that No. http://www.dailymail.co.uk/news/article-444819/UK-1-worlds-population-20-CCTV-cameras.html The analysis One camera for every 14 people comes with a partner statistic: that there are 4.2 million security cameras in the UK. The pair of claims come from a working paper published in 2002, by academics Michael McCahill and Clive Norris. FactCheck alarm bells are already ringing. It's now 2008, so is the figure still up to date? It's hard to say, as there are no official (or even unofficial) statistics on how many CCTV cameras there are. The information commissioner doesn't know, the government has repeatedly told parliament that figures are not collected, and any tally of publicly funded cameras wouldn't cover any small screens set up in the likes of cornershops. We can look, however, at how the Davis-quoted figure was calculated. The basis comes from a survey of the number of CCTV cameras in two busy south London streets, Putney High Street and Upper Richmond Road. The researchers sampled 211 "premises" - banks, estate agents, pubs, shops and office blocks - and found that 41 per cent had CCTV systems, with an average of 4.1 cameras per system. By assuming this is "broadly representative" of CCTV coverage across the whole of London, the authors estimate that 41 per cent, or 102,910, of the 251,000 VAT-registered businesses registered in London would have a CCTV system. Multiply this by 4.1 and there would be 421,931 cameras. They then add the cameras operating in other public institutions - such as open-street systems, transport, hospitals, schools etc - and reckons it's "not unreasonable to 'guesstimate' that Londoners are monitored by at least 500,000 CCTV cameras". Maybe it's not unreasonable, but it's hardly concrete proof, either. The report then estimates that, as London has 7.2 million residents and the UK has around 60 million, the country has at least 4,285,000 cameras, approximately one for every 14 people. Bingo - there's the claim, but we've got to it based on two London streets, multiplied out to reflect the whole of London, and then multiplied again to reflect the whole country. http://www.channel4.com/news/articles/society/factcheck+how+many+cctv+cameras/2291167.html Big Brother is DEFINITELY watching you: Shocking study reveals UK has one CCTV for every 32 people The research involved police community support officers counting every camera in Cheshire and extrapolating the results nationwide to provide a reliable estimate of the level of CCTV surveillance in the UK. Officers counted 12,333 cameras in the area, according to a study published in CCTV Image magazine, the majority of which were inside premises, rather than facing public street. The research also found that most CCTV cameras in the UK are likely to be privately owned, with only 504 of Cheshire’s cameras run by public bodies.
