According to a 2010 Fox News report, Pakistan had outranked all countries in Google searches for pornographic terms last year. Narrowing the analytics for the search term to just 201 1 , Pakistan maintained the number one position, followed by India and Vietnam. Islamabad featured in the top 10 cities worldwide to search the word 'sex' in September and December 2011.Provincial capital Lahore also featured in the top 10 cities for the months of January, March, April, May, June, July, September, October, November and December 2011.The months of February and August (Ramazan) were the only two months in 2011 that did not feature any cities from Pakistan in the global ranking.Google Trends analyzes a portion of Google web searches to compute how many searches have been done for the terms entered, relative to the total number of searches done on Google over time.To rank the top regions, cities, or languages, Google Trends first looks at a sample of all Google searches to determine the areas or languages from which they received the most searches for the first term. Then, for those top cities, Google Trends calculates the ratio of searches for the term coming from each city divided by total Google searches coming from the same city.The city ranking and the bar charts alongside each city name both represent this ratio.Google Trends uses IP address information from server logs to make a best guess about where queries originated.
