The study, which collected results from 1,341 grandparents from the UK, showed that 71 percent of grandparents which are using a social network use Facebook, 34 percent are on Twitter and 9 percent use the business social network LinkedIn.
A great deal of these users, is quite active, too: 51 percent says they log in once a week or more, and 35 percent only log in a few times every month.
68 percent of those asked said they had joined their chosen social network in the past year. One quarter of participants said they had joined a social network to find old friends, one fifth said they did it to keep in touch with friends and family, and half were encouraged to do so by younger people in their families.
This latest study, although limited to UK citizens, is in line with other similar recent studies. A Pew report from 2010 indicated that the number of seniors who are using social networking is growing rapidly, while another report from that year showed that baby boomers are increasingly joining Facebook.
