In 2016, there were an estimated 4.7 million internet users in Singapore, representing 82.5% of the population. The Singapore government does not engage in widespread censoring of the internet, but it maintains a list of one hundred websites—mostly pornographic—that it blocks as a "symbolic statement of the Singaporean community's stand on harmful and undesirable content on the Internet". As the block covers only home internet access, users may still visit the blocked websites from their office computers. Singapore has the world's highest smartphone penetration rates, in surveys by Deloitte and Google Consumer Barometer – at 89% and 85% of the population respectively in 2014. Overall mobile phone penetration rate is at 148 mobile phone subscribers per 100 people.
