Building on African migration as a household survival strategy; urban–rural linkages as critical for migrants' continued engagement with origin communities; reintegration in case of return; and safety net for supplementing precarious urban incomes; we examine the role of family ties in rural origin linkages among 1,693 older migrants living in Nairobi informal settlements. Despite the grim of slum residence, 80% of older migrants in Nairobi slums maintained contact with their rural origin homes during a full year of observation. Family‐related factors, especially members of the nuclear family residing in rural origin, explained 45% of explained linkages. Religion, ethnicity, land ownership at origin, and current health and economic statuses are other key predictors. The patterns and reasons of linkages are consistent with migrants' positive contributions to the upkeep of rural origin households. Our findings are well‐anchored in the larger continental literature that has shown the urban migrant as not a ‘disembedded individual’ but instead part of rural origin collectives. Against the weakness of state safety net system, the study sheds crucial light on the enduring importance of sociocultural networks in people's everyday lives, particularly the importance of family ties for older migrants. To the extent that poor health status, being aged 60 years or older, and long duration of residence in the slums, which are predictors of low propensities to maintain contacts with rural origin, are also indicators of diminished social engagement, policy interventions among the urban poor may need to include efforts to enhance rural origin reintegration of the most‐aged individuals.

Circular and return migrations between rural and urban areas in sub-Saharan Africa have persisted over time, driven by a combination of socio-cultural, economic, and structural forces. Much of the literature on migration in Africa focuses on labour migration. However, old age also marks a stage in the life course often associated with migration. This paper examined the determinants of out-migration among older people living in the slums of Nairobi. The paper used a prospective population study of 2,270 older people, followed up over a 3-year period. The annual rate of out-migration was 4%. Cox proportional hazard analysis was used to model the effect of ties to place and to socio-economic capital on propensity to out-migrate. The presence of adult children outside the city was a significant pull factor for both men and women. The propensity to out-migrate decreased with length of residence in the slum. Attachment to the slum through participation in voluntary communal activities was also negatively associated with out-migration, particularly for men. The poorest older people were more likely to leave the city, highlighting the effect of deprivation in triggering return migration. Looking at future migration intentions, only one in five older people reported that they intend to relocate from the slums, highlighting that, in the future, there will be a growing number of people ageing 'in situ' in poor urban areas. This has implications for policy makers concerned with the provision of services to vulnerable older people who may be unable to engage in livelihood strategies as health deteriorates with age.

Using self-reported health that assesses functionality or disability status, this paper investigates whether there are any differences in health status among older people living in a deprived area of Nairobi, Kenya. Data from a cross-sectional survey of 2,037 men and women aged 50 years and older are used to examine the association between socioeconomic position and self-reported health status across 6 health domains. Education, occupation, a wealth index, and main source of livelihood are used to assess the presence of a socioeconomic gradient in health. All the indicators showed the expected negative association with health across some, but not all, of the disability domains. Nonetheless, differences based on occupation, the most commonly used indicators to examine health inequalities, were not statistically significant. Primary level of education was a significant factor for women but not for men; conversely, wealth status was associated with lower disability for both men and women. Older people dependent on their own sources of livelihood were also less likely to report a disability. The results suggest the need for further research to identify an appropriate socioeconomic classification that is sensitive in identifying poverty and deprivation among older people living in slums.

This paper examines gender differentials in survival amongst older people (50+ years) in the Nairobi slums and to the best of our knowledge is the first study of its kind in an urban African setting. The results provide evidence contrary to the expected paradox of poorer self-rated health yet better survival amongst older women. Older women in the Nairobi slums have poorer self-rated health and poorer circumstances across other factors, including disability and socio-economic status. Further, older women in the slums do not have better survival. The conventional female advantage in mortality only becomes apparent after accounting for the cumulative influence of individual characteristics, social networks, health and socio-economic status, suggesting the female advantage in unadjusted old-age mortality does not apply to contexts where women experience significant disadvantage across multiple life domains. This highlights the urgent need to redress the support, status and opportunities available for women across the life course in contexts such as the Nairobi slums. In addition, a greater number of factors differentiate mortality risk amongst men than amongst women, suggesting inequality amongst slum dwelling older men and highlighting the need for gender sensitive interventions which account for the particular needs of both genders in old age.

Older people in slum settings are a vulnerable sub-group during crises, yet have received minimal attention in the development discourse. This paper examines the protective role of different types of social networks for older slum dwellers' wellbeing during adversity by investigating the relationship between social networks, the Kenyan 2007/08 post-election violence, and dimensions of wellbeing namely self-rated health, life satisfaction and happiness amongst older people in the Korogocho slum, Nairobi. The analyses are based on conditional change logistic regression models using data from a unique longitudinal survey of the health and wellbeing of older people. The results show that maintaining or increasing formal local networks reduced the detrimental effects of the post-election violence for older people's wellbeing, whilst household environment and informal local and non-local networks did not influence the relationship. Consequently, the paper provides evidence that supporting inclusive community organisations which are accessible to older people can be valuable in promoting the resilience of this population group.
