Abstract
This theme investigated the linkages between migration, poverty, and health consequences at each stage of the life-course among people living in Nairobi's informal settlements. It specifically addressed objective 1.4 of the UPHD project as stated below:



1.1 Determine the characteristics of in- and out-migrants, their migration histories, reasons for migrating, and nature of links with origin communities;

1.2 Investigate how changing poverty and health circumstances influence and are influenced by intra-urban and urban-rural migrations;

1.3 Assess the motivations for migration (e.g. health-related reasons) and how this has an influence on estimates of mortality and fertility levels in informal settlements;

1.4 Validate the relevance of various measures of poverty in informal urban settlements.
