70% of Active Online Americans Visit Facebook

70% of Active Online Americans Visit FacebookWith Facebook’s IPO dominating headlines this week, some new numbers regarding the company’s reach – both in the U.S. and worldwide – have recently been released.

Facebook says that it has 901 million global monthly active users, and that half of its revenues in the first quarter of 2012 were generated outside of the U.S. and Canada.

New data from Nielsen takes a closer look at Facebook’s reach in the U.S. and in some international markets.  The U.S. still has the most Facebook users overall – 152.8 million users – based on usage from both computers and mobile devices. Facebook’s active reach in the U.S. is just under 70% – meaning that more than 2 out of 3 Americans who were active online in March 2012 visited Facebook.

New Zealand has the highest active reach, according to the Nielsen data, with nearly 80% of all consumers online accessing Facebook by computer or mobile device. However, in terms of overall penetration, Facebook only reaches 51.4% of the country’s entire population, according to data from Social Bakers.

Brazil has the highest active reach for those who visit Facebook from just home or work computers, with 76.7%, or 38.1 million Brazilians visiting Facebook in March 2012.  TechCrunch points out that this number doesn’t match Facebook’s figure (released in its latest S-1) of 45 million monthly active users in Brazil – perhaps the discrepancy can be explained by those who access Facebook via mobile only (not included in the Nielsen statistic).  And despite the country’s high active reach among internet users, Facebook’s actual penetration is only 23.4% of the entire Brazilian population (Social Bakers).

In Japan, Facebook’s active reach is only 24% – according to TechCrunch, blog sites are much more popular in that market, and Pinterest is also growing quickly there.  Facebook penetration for the overall population is only 7% in this market, leaving tons of room for growth or for other social networks to step in.
