LAWRENCE — A new study that is the first to use Social Security Administration’s personal income tax data tracking the same individuals over 20 years to measure individual lifetime earnings has confirmed significant long-term economic benefits of college education.
ChangHwan Kim, a University of Kansas researcher, said the research team was also able to account for shortcomings in previous studies by including factors such as gender, race, ethnicity, place of birth and high school performance that would influence a person's lifetime earnings and the probability of college completion.
