After reading an article about who doesn’t get into Harvard, I wondered: who does get into Harvard these days?

If we plot the undergraduate admission rates for Harvard, MIT, and Stanford for the past seven class years, we see a trend towards higher selectivity. One driving factor is that class sizes have stayed relatively constant while the population at large has grown. Will the decline in the US birth rate ease the competition?
