Divorce Marriages

What is the rate of marriages ending in divorce per 1000 population?
I need help trying to answer 2 questions:
What is the rate of marriages ending in divorce per 1000 population in 2007 and 2008?
What is the % of people never married between the ages of 30-34 for 2004 and 2008?
I’ve been looking on census.gov but can’t find this information. Any help on exactly where to go or what to search would be helpful.
2007 = 998
2008 = 999
69%
