The second table in this cluster clearly represents the higher-wage (correlating to higher skill) occupations. Aerospace engineers ($43.31/hour) and Electronics engineers ($40.40) stand out in particular, though both have seen a dip in job numbers.
The precipitous drop in truck driving positions is startling — more than 133,000 drivers have lost their job since 2007. At more than 1.8 million, however, Truck drivers still make up the biggest chunk of the Transportation cluster.
Most of growth in this sector comes from occupations that are composed of fairly few workers, namely Railroad conductors and Locomotive Engineers.
