With these data in hand, we may proceed to our sectoral analysis, starting with die service sector. Remembering the point made above that die number of service personnel (whether doctors or chimney sweeps) is ultimately dependent upon the odier more in- dependent activities in the town, the readers/need not be unduly impressed by the proportions we find ascribable to this sector. From Kulikoff's data, it would appear/tnat at least 45 percent of Boston's tax-inscribed adult males in 1790 were employed in the service sector. The equivalent figures are 48.93 to 49.29 percent for Philadelphia and 46.7 to 56.5OŁercent for New York. In general, it seems safe to say that, in aji'substantial colonial towns, the service sector broadly conceived/accounted for around 50 percent of the employed adult male population. (The proportion would probably be even higher in tjze enumerated towns if we could get accurate information on slaves and women and on apprentices and other employees wWresided on the premises of their employers.) Much rigorous quantification remains to be done, but the burden of proof lies on thjtfse who would claim that other towns might have had significantly different patterns. Of course, however finely measured, die iinpressive size of die service sector tells us nothing about die raixn d'etre of die town or of its ultimate proportions. To under- id diem, we must try to measure the more independent vari- 'ables: the public, industrial, and commercial sectors.
