If my family are anything to go by, they definitely target the elderly more than even one generation down (so it isn't just due to those of the younger generations often only having mobile phones and landlines are more targeted) because they know those tend to be more susceptible to the con and more likely to have some savings worth pillaging.
Also in DayJob, some of our C*s and others associated with them (PAs, office managers) have seen some pretty sophisticated phishing attempts, both targeting the business's dealings and their personal accounts. I get the impression that these are reducing in number ATM (or the filtering of them is improving) but that those coming in are making an increasing effort to be convincing.
