A review of sociological and historical research into long-term social
mobility shows a common research agenda linking total mobility, relat
ive mobility, and stratification to industrialization, as well as powe
rful methods to test hypotheses on widely available historical data. T
o demonstrate the viability of such a historical approach, social mobi
lity and stratification in Berlin between 1825 and 1957 are analyzed.
Intergenerational as well as marital total mobility rates show no corr
elation with industrialization. However, with respect to relative inte
rgenerational mobility, the Berlin data corroborate the hypothesis of
a gradual growth in 'openness' more than the hypotheses of no change,
or of a one-time increase during early industrialization. For marital
mobility no trend in relative mobility is evident.
