Although the largest Facebook.com markets by audience size are the United States, Germany and India, many of the most highly penetrated markets for the social networking giant are in Latin America. In fact, five of the top 10 markets for Facebook.com penetration are in the region. Facebook.com reached 90.9 percent of all online users in Chile, ranking as the third most highly penetrated market globally behind the Philippines and Turkey. Argentina, Colombia and Peru immediately followed Chile, with all markets seeing Facebook.com reach more than 89 percent of their Internet populations, while the site reached 86.9 percent of online users in Venezuela.
These findings are part of the recent comScore report, The Rise of Social Networking in Latin America.
