<p>Collegeboard.com provides some information on the favorite majors at each college. I did a review of the Top 20 schools (as ranked by USNWR) and uncovered some interesting facts. Data was presented for 19 of the 20 schools (Princeton not provided) for each of the majors where 5% or more of the students had declared this area of study. This accounts for just under 80% of the declared majors at these schools. </p>
<p>Note: The % number for the major category is for the percentage of the total number of students at the 19 schools being measured. However, the numbers given for each school are representative of the % of students on that particular campus who are pursuing that major. </p>
