Higher education in the United States has been viewed as recession-proof, but the global financial crisis is already having an impact. Here are some facts about enrollment, endowments, and finances at the nation's colleges universities.

- An Oct 16 report from Moody's Investors Service estimated endowment losses at 5 per cent to 7 per cent in the year to June 30. Since then, spending and endowment losses sliced another 30 per cent off schools' cash and investments.

- For the nation's public universities, which educate three out of four students, state subsidies covered a little over half of their budget costs last year, down from two-thirds in 1998. Tuition has grown to cover more than a third of their budgets, up from one-fifth 15 years ago.

- Endowments supported around 10 per cent of the average school's budget. At Harvard (endowment US$34.6 billion as of June 30), Yale (US$22.5 billion), and other wealthy institutions, earnings from the endowment covered roughly 40 per cent of costs. The average expenditure out of wealthy schools' endowments was 4.4 per cent of assets.

- A total of 76 colleges and universities had more than US$1 billion in their endowments as of June 30. The wealthiest 400 schools had more than US$400 billion in assets in 2007. But fewer than 400 schools had at least US$100 million in their endowments, with most having less than US$10 million.

- Tuition, room and board at private four-year schools in 2007-2008 averaged US$31,019, up 7 per cent from two years ago after adjusting for inflation. The cost of public schools was US$16,758 for in-state students, US$24,955 for out-of-state students, up 5 per cent in the last two years after inflation.

- Federal loan aid for higher education increased 60 per cent between 1996 and 2005. Students borrowed US$77 billion last year to pay expenses to attend colleges and universities. Two out of three students received grants - discounts on tuition - averaging US$9,300 at private schools and US$3,600 at public schools.

- College seniors who graduated in 2007 carried 6 per cent more student loan debt that the class of 2006. Starting salaries for graduates rose 3 per cent in the same period.

- An online survey found 16 per cent of prospective students put college searches on hold because they couldn't afford it.
