This article uses evidence from the manuscripts of the 1860 federal ce
nsus to analyze the wealth of adult males in Boston, New York, Chicago
, and Indianapolis. Previous multivariate analyses of wealth from the
census have been flawed by reliance on ordinary least squares; we inst
ead use quantile regression. Immigrants fared considerably better in t
he Midwest than the East: immigrants in the midwestern cities held mor
e wealth than their eastern counterparts, both absolutely and relative
to the native-born in their respective cities. We explore the causes
of these differences and their consequences for nineteenth-century Ame
ricans and their communities.
