This article is the seventh, or final one, in a series of seven that examines key industrial sectors to determine where they are most significant regionally. Rankings of state strength in each industrial sub-sector are based on both ‘weight’ and ‘concentration’ of relevant employment.
‘Weight’ is simply the number of jobs in the industrial sub-sector in each state. ‘Concentration’ is each state’s number of jobs in the sub-sector divided by the state’s population. In effect, it’s a ‘per capita’ figure, except that it’s expressed as number of jobs per million population.
By ‘weight’, the states with the largest populations are almost always high in the rankings. The rankings by ‘concentration’, however, often expose some unexpected winners.
