Crosby's recent study of American historical demography is blithely based
on the reconstitution of the records of single parishes, a method that often
excludes migrants. Moreover, it is troublesome for historians to obtain
Line information on the birthdates of people who relocated to the parish, and equally
(5) difficult to follow those who had migrated to new places of residence. Thus, the
exclusion of migrants also followed from the way spatial units were once
conceived by the parishioners themselves, a stable and unchanging pre-modern
countryside of interchangeable towns unlike "modern" flows to cities.
As a result, migration was improperly assumed to be irrelevant because the
(10) small units in the countryside were interchangeable and migrants into a parish
could thus stand as a proxy for those who had left. In any case, it was thought
that migration in the countryside was repetitive and occurred only in response to
life course events, such as finding a spouse, and thus, like the parishioners
themselves, Crosby complacently equates the demographics of migrants to those
(15) of more sedimentary populations.
