Markos Moulitsas is linking to a new survey of readers of the DailyKos website. The survey was done by something called comScore Networks, and it is not clear who commissioned it, but it appears to be quite pro-Kos. In any event, the survey shows that about 60 percent of Kos readers are 45 years old and over (with 22 percent over 65). About 60 percent of them make more than $75,000 per year. And, just like the electoral map of recent elections, they are clustered along the West Coast, as well as the Northeast and Upper Midwest. Here are the age and income numbers:

Age % of visitors

18-34 20.7

35-44 17.5

45-54 27.7

55-64 12.2

65+ 21.9

Household Income

Under $25,000 2.8

$25,000 – 39,999 9.4

$40,000 – 59,999 20.4

$60,000 – 74,999 7.9

Over $75,000 59.4

One bit of information that would have been interesting to know is the racial composition of the DailyKos readership, but that was not included in the data comScore made public. Moulitsas has claimed that the site’s readers represent “a real cross section of the Democratic Party, a real cross section of America.” Black voters, of course, are a major part of the Democratic coalition, but anyone who attended the YearlyKos convention or other events involving “progressive” bloggers, would guess that the blogs’ readership is more than 90 percent white.
