An article on Sept. 13 about college tuition referred incorrectly to CUNY when describing a program that helped improve the graduation rates of its community colleges. It is the City University of New York (not Universities). The article also referred incorrectly to a measure of income in a comparison of 1974 income and current income when adjusted for inflation. It is median family income, which has risen to about $64,000 a year from $62,000 in 1974, not median household income. And the article also described incorrectly the change in median family income over the past 40 years. It has risen slightly, not fallen.
