A quick summary:
Median salaries: New B.S. and Ph.D. graduate salaries were down from 2012 (39.6k for B.S. grads, down from 40.0k, 75.8k for Ph.D. grads, down from 80.0k.) M.S. new grad salaries were up to 55k from 48.0k in 201. Interesting to see the numbers in constant 2005 dollars, which reflects those numbers even more starkly.
Employment/unemployment: Up slightly for B.S. grads to 37%, from 2012's 34%. M.S. grad employment was down slightly to 48%, with Ph.D. grad full-time employment flat at 46%. The unemployment of B.S. new grads (20%) was at an 8 year high. M.S. new grad unemployment was at 19%, the second highest in 8 years, with the exception of 2011 (23%). Ph.D. unemployment was at an eight-year low at 6%.
Like swallows to Capistrano: Surveyed chemical engineers beat out chemists on all measures, with the exception of full-time employment for M.S. chemical engineers.
Academic employment up? I don't remember this statistical category from other years, but it is surprising to me how many (B.S.: 37%, M.S.: 44%, Ph.D.: 47%) took employment in academia, as opposed to industry (30%, 35%, 24%) or "other non-manufacturing" (25%, 12%, 21%.) This doesn't include graduate school or postdoctoral fellowships (I don't believe), so it's interesting to see how many of the non-doctoral survey respondents took technician/staff positions at universities.
The Eka-Silicon caveat: The response rate for the 2013 ACS Starting Salary Survey was 17.8%. That's a pretty low number, but about typical for the Starting Salary Survey. This means that the numbers are pretty noisy from year to year, so take these statistics with a grain of salt.
