The report was also able to determine that 20 million of those users pinned, repinned or liked a pin in June 2013. Semiocast also found that 79% of those active users are based in the U.S. (The researchers determined geographical information by compiling users’ declared location.)
When I reached out to verify the report, Pinterest’s Head of Communications told me that they don’t disclose internal numbers.
However, he did suggest that a February 2013 Business Insider post reporting 25 million registered Pinners was quoting a third-party number for users located in the U.S. and referred me to a Reuters article from the same month citing digital analytics giant comScore, which reported 48.7 million unique monthly visitors worldwide.
A full summary of Semiocast’s findings is available for viewing here.
