Use of online classified ads over time, by demographic group The percentage of each demographic to use online classified ads in 2005 and 2009.
Over the past four years, the demographic makeup of online classified users changed very little. The percentages of demographic groups using online classifieds grew at a rate that mirrors the growth of the total online population using these sites: the percentage of all internet users to utilize classified sites grew 27 percentage points from 2005 to 2009, while most other demographic groups’ growth ranged from 25 to 29 percentage points.
The exception to this pattern involves different generational use of classified sites. Online 18-29 year olds saw a 30 percentage-point increase in their use of online classified ads, and 30-49 year old internet users marked a 32 point increase in online classifieds use. On the other hand, internet users ages 50-64 saw a 21 point increase, and online seniors (age 65+) saw the smallest increase overall: 13 percentage points.
