Division of labor, specialization and diversity in the ancient Roman cities: A quantitative approach to Latin epigraphy.

Employing the bootstrap test, we see that despite an obvious trend, most of the differences are not statistically significant, with a few notable exceptions: First, there is a statistically significant difference between the mean count of occupation terms in a random sample of inscriptions derived from all city contexts combined and the count of occupation terms in sample from rural areas, and second, there is a statistically significant difference between the count of occupation terms in a sample from small cities and the count of occupation terms in a sample from rural areas.
