«Once I published this article in Radio & Records noting the difference in listening between college grads and non-college grads, I have been rightfully asked the following question: "Has it always been this way?" So I looked at the diary data from the sample of diarykeepers from our longstanding series of studies with Arbitron.

In 1998: Non-College Grads ages 25-54 listened to an average of 102 Quarter-Hours per week

College Grads ages 25-54 listened to an average of 86 Quarter-Hours per week

In 2008: Non-College Grads ages 25-54 listened to an average of 100 Quarter-Hours per week

College Grads ages 25-54 listened to an average of 70 Quarter-Hours per week

In addition, the portion of 25-54s that are College graduates increased from 33% of 25-54s to 41% of 25-54s.  What does this mean? That nearly all the 25-54 losses in TSL over the last decade are coming from college grads. The Non-grads are listening virtually the same amount.» Has Radio Lost the College Grads?
