Nine Out of Ten 25-34 Year Old U.K. Internet Users Visited a Social Networking Site in May 2009

Internet Users Age 55 and Older More Likely to Visit Social Networking Sites than Business & Finance, Technology and Travel

LONDON, U.K., July 20, 2009 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released the results of a study into U.K. social networking site usage by age of visitor, based on data from the Comscore World Metrix audience measurement service. The study found that 29.4 million people accessed at least one social networking site in the U.K. in May, averaging 4.6 hours per visitor during the month, with Facebook.com ranking as the most visited social networking site.

Social Networking Reach High Among All Age Groups

Social networking has become a mainstream online activity among all age groups, with 80 percent of the total U.K. online population having visited a site in the category in May. Penetration was highest amongst 25-34 year old Internet users, 89 percent of whom visited the category during the month, followed by 15-24 year olds (86 percent). Category penetration was somewhat lower among the older age groups, but remained relatively high, reaching two thirds of the total online population age 55 and older.. Comparatively, slightly more people from this age group visited a social networking site in May than visited a business & finance (63 percent), technology (62 percent) or travel site (52 percent).

Engagement also skewed more heavily towards the younger age segments, with 15-24 and 25-34 year olds averaging 5.4 hours per user per month compared with 3.7 hours per month among users age 55 and older. Overall, social networking was the second most popular online activity in the U.K. based on average time spent per user (4.6 hours), trailing only instant messaging (8.6 hours).

“Accurate demographic profiling is the crux of effective digital media planning and advertising,” said Mike Read, SVP and managing director, Comscore Europe. “Understanding audience composition is particularly important in a category such as social networking, as there continues to be a misconception that social networking is the preserve of the young. While those under 35 years old are certainly the more prevalent users, there is both a sizeable and heavily engaged audience of those 35 and older as well. In fact, advertising on social networking sites has a better chance of reaching these older demographics than site categories such as business and finance, which is a critical insight that might be lost for those trying to optimize their campaign against target audience segments.”
