A survey of 13,414 students in a country who enrolled in private career colleges was conducted to understand student participation in the private postsecondary educational system. In one part of the survey, students were asked about their field of study and about when they entered college. Here are the results.
Field of Number of Time of Entry
Study Students
Right After High School Later
Trades 942 34% 66%
Design 584 47% 53%
Health 5085 40% 60%
Media/IT 3148 31% 69%
Service 1350 36% 64%
Other 2255 52% 48%
In this table, the second column gives the number of students in each field of study. The next two columns give the marginal distribution of time of entry for each field of study.
The survey also asked about how these college students paid for their education. A major source of funding was government loans. Here are the survey percents of private students in the country who use government loans to finance their education by field of study.
