Source: Source: PayScale.com. Data used in the College Salary Report came from surveys completed by roughly 1.4 million college graduates of 1,002 colleges and universities, which represent 75% of all bachelor's degree recipients in the U.S. Graduates with advanced degrees were excluded from the results. Only full-time, civilian workers based in the 50 states and District of Columbia were counted. The ranking is based on mid-career results, which comes from median salaries of graduates with 10 years of work experience. Whether a job is meaningful is based on the percentage of graduates who answered "Very much so" and "Yes" to the question: "Does your work make the world a better place?"
