A report from Lucid Marketing titled “U.S. Adults: Word of Mouth Communications” (you have to take reports from marketing agencies with a small grain of salt) has found that:
Women were more likely than men to share a positive experience with a business (91% to 83%) or recommend an enjoyable product (95% to 89%). And, full time employees made substantially more daily contacts than those not in the workforce, while those with household earnings of more than $100,000 were more likely to make recommendations than those earning less. The study showed that women tend to prefer verbal communications to other forms of contact, whereas men tend to prefer email.
Other findings include that 49% of Gen Y have built a website and one quarter have their own blog, while Gen X and Boomers tend to use email more often and are more likely to spread positive WOM.
