Ok, so ‘net useage/marketshare and social networks skew young… but the tonnage, the shear volume, is with adults.
75 percent of online adults 18 to 24 have a profile on a social networking site.
57 percent of online adults 25 to 34 have a profile on a social networking site.
30 percent of online adults 35 to 44 have a profile on a social networking site
19 percent of online adults 45 to 54 have a profile on a social networking site.
