<p>But remember the difference between a variable and its first derivative (i.e. the number of jobs versus the growth rate of the number of jobs). Also note that the ease of getting a job and how well it pays also depends on the number others in the field.</p>
<p>Civil and environmental engineering jobs were cyclically hit hard in the construction crash, so the number of jobs and pay levels should grow back when construction recovers. Biomedical engineering is starting from a low base, but it seems to be rather popular with students (i.e. a pretty large supply leading to lower pay levels).</p>
