With the ongoing public offering, the ‘is it worth $100bn’ debate or, indeed, the steady stream of stories on social media trolls, the site has never been as ubiquitous as it is today. Nielsen marked Facebook’s $1oobn floating in New York this week by releasing their latest figures on Facebook’s reach – the percentage of Internet users who visited Facebook last year – in twelve major international countries.

The population numbers are current up to 2010 and taken from the World Bank’s figures, with the exception of Taiwan, which I got from the CIA World Factbook.
