College tuition costs rose again this year. In-state tuition at public colleges increased to $10,560, up $120 from last year. Tuition at private colleges rose to nearly $38,000, up 2.1%. Over the past 10 years, college tuition has increased by an average of 4.5% per year, compared to a 1.3% annual rise in average consumer prices, making college increasingly unaffordable for many families.
