Need statistics and research for USA and New Jersey college enrollment and graduation for adult populations

I need any data, statistics and research for ALL of the following topics. This data and topics is to track and identify the college enrollment and activity of non-traditional, "adult" student populations. By "non-traditional, adult" populations, we are referring to students that are usually 23 and older... so traditional age college students are students that come into college right after high school and are ages 18-22.... but non-traditional, adult populations are usually students that went into the workforce after high school and then decided to go to college later in their lives.

I need research and statistics for these topics:

1) trend in college enrollment for non-traditional, adult populations
a.) for overall USA
B.) For New Jersey colleges

2) Retention rates after first and second year for non-traditional and adult populations
a.) for overall USA
b.) for New Jersey colleges

3) graduation rates for non-traditional and adult populations
a.) for overall USA colleges
b.) for New Jersey Colleges

4) percentage of non-traditional, adult students that are parents
a.) for overall USA colleges
b.) for New Jersey colleges

5.) average student loan amount for non-traditional, adult students
a.) for overall USA colleges
b.) for New Jersey Colleges
