It's both impossible and pointless to try to correlate distracted drivers with any demographic group.
This issue isn't about demographic groups or classes of drivers, it's about individual drivers being overly distracted.
There are many contributory factors, ranging from technological changes offering new ways to be distracted, sociological factors whereby people are more used to multitasking (with various degrees of skill going up from zero), to design changes in cars themselves which tend to take eyes from the road more.
However, it's still about individual drivers. For example, while many or even most of us drive with a cell phone in the car, we are not compelled to answer while driving. Some may always answer, others never, and the rest deciding based on the conditions at the time.
What is safe to say, is that it's rising both in frequency and degree (distraction isn't binary), and is likely to continue until something changes to reverse the trend.
