Where can I find Harvard acceptance rate by year, and how should I interpret the trend?

The cleanest place to find Harvard acceptance rate by year is Harvard’s own admissions announcements and Common Data Set archives. Harvard College Admissions often publishes the number of applicants and admits for each entering class, and those figures are the most reliable source if you want year-by-year rates.

You can also use Harvard’s Common Data Set, which usually includes total applicants, total admits, and other admissions breakdowns. If you are comparing across many years, the key is to make sure the numbers all refer to the same thing: usually first-year applicants and first-year offers of admission for one admissions cycle.

When different sources show different percentages, it is often because they are mixing early and regular data, using rounded figures, or comparing the admissions cycle year with the entering class year. Some sources also include transfer acceptance rates separately, which should not be mixed into the freshman rate.

The long-term trend at Harvard is clear: the acceptance rate has generally fallen over time because applications have risen much faster than the number of available spots. That means the rate reflects both Harvard’s selectivity and the size of the applicant pool. A lower rate does not always mean each applicant is dramatically stronger than in prior years, but it does mean admission has become statistically harder.
