Abstract
Conceptually migration can affect fertility through adaptation, selection, disruption or
socialization. This effect can be expressed in children ever born, timing of birth, contraceptive
use or conception. The study attempts to examine the impact of migration on fertility (children
ever born and timing of birth) with regard to adaptation and disruption hypothesis in Addis
Ababa Ethiopia using data from the 2016 Ethiopian Demographic and Health Survey. To discern
the effect of migration on cumulative fertility and timing of birth Poisson regression and discrete
time event models were fitted. Poisson regression model is explored to study the impact of
migration on mean CEB with respect to adaptation model while; discrete time event model is
explored to study the effect of migration on delaying timing of first and second birth in respect of
disruption model. Migrants were compared with non-migrants living in Addis Ababa. In
addition, characteristics of migrants by duration at place of destination are also examined and
compared with those non migrants. The study reveals non-significant relationship between
migration and lifetime fertility of women which is against to the concept of adaptation
hypothesis. The results also indicate there is difference in hazard of first and second birth
between migrants and non-migrants. However, this evidence strengthens migration effect in
delaying timing of first and second birth for migrant which support disruption hypothesis. The
study finds that migrant adaptation in fertility was not evident but gives speculative evidence for
fertility disruption of migrants for first and second birth in the context of Addis Ababa. Future
researches further investigate determinants of migrant fertility in Addis Ababa and also examine
the relationship with regard to other fertility differentials (selection and socialization).
