The Dispersion of Knowledge: A Data Point
The Bureau of Labor Statistics has updated its job classification system. Theresa Cosca and Alissa Emmel report,
Compared with the 2000 SOC system, the 2010 SOC system realized a net gain of 19 detailed occupations, 12 broad occupations, and 1 minor group. Table 2 compares the hierarchical structures of the 1980, 2000, and 2010 SOC systems.
When I was writing Unchecked and Unbalanced, I found it difficult to document that knowledge has become more specialized and dispersed over time. This is the sort of data point that might support that proposition. However, the changes between 1980 and 2000 were much larger quantitatively than those of the last ten years.
