I need references to several studies showing what factors determine
how many hours a person watches TV per week. Specifically, I need
studies examining the relationship between at least 5 of the following
7 variables to amount of time spent watching TV:
1. Race
2. Income
3. Education 
4. Sex
5. Marital Status
6. Age
7. Size of Household

So, for instance, a scholarly article that finds that "blacks watch
2.4 more hours per week than whites" would suffice for one of the 5
needed variables.
