Google says searches for "porn" reached an all-time high in 2005
Web surfers in Birmingham are more likely than those in any other city to search for pornography, according to internet search engine Google.

Google Trends analyses the type of searches made from different cities around the globe.

Manchester came second, followed by Brisbane, Perth, Sydney and Melbourne. Brentford, in Middlesex, was seventh.

The facility showed that the amount of searches on the word "porn" reached an all-time high in 2005.

Google Trends works by sampling all searches matching a single word and determining the cities from which it received the most hits.

From those top cities, the ratio of searches is calculated by dividing it by the total Google searches coming from the same city.

Google uses IP address information to make a "best guess" about where the queries originated.
