How many 18-34 year-olds account for the US population?
How many of this demographic is ?online??
What is the average Household Income?
What is the total US buying power of this demographic (estimated retail sales)?

The article here: http://www.cabletvadbureau.com/02Profiles/MTVProf.htm
represents MTV's demographic of US 12-34 year-olds.
We would like information on this same demographic specific to
internet users. Such stats in the article as: ?In the past year, MTV
viewers 18-34 have spent: ? $8 billion of on clothing expenditures  ?
$845.5 million on video game systems ? $2.2 billion on fine jewelry ?
$5.5 billion on major household furnishings ? $885 billion on audio
equipment ? $5.3 billion on foreign vacations? are very useful.
The article?s data is somewhat dated with Nielsen 2003 figures. We
need the most recent reporting data as well as previous years.
