Family reconstitution results for two industrializing townships in West Yor
kshire are compared with findings from Cambridge Group reconstitutions and
from similar European studies. The research highlights the variety of demog
raphic experience between and within communities which experienced similar
structural, economic, and technological shifts. This suggests that the cons
truction of typologies of demographic change based on dominant occupations
or sectors may be misleading, as may the assumption that economic transform
ation acted uniformly upon local populations. Aggregate shifts in demograph
ic indicators in the townships appear to have been driven by significant ch
ange in the experience of relatively small, identifiable subgroups and coho
rts. Rural industry seems to have stabilized communities, as well as changi
ng them, and localized practices, culture, and responses conditioned and pa
rticularized economic change itself.
