  We studied residential clustering and mobility of ethnic minorities using a
theoretical framework based on null models of spatial distributions and
movements of populations. Using microdata from population registers we compared
the patterns of clustering amongst various socioethnic groups living in and
around the capital region of Finland. Using the models we were able to connect
the factors influencing intraurban migration to the spatial patterns that have
been developed over time. We could also demonstrate the interrelationship of
the movement and clustering with fertility. The observed clustering seems to be
a combined effect of fertility and the tendency to migrate locally. The models
also highlight the importance of factors like proximity to the city-centre,
average neighbourhood income, and similarity of socioeconomic profiles.
