Societal change related to individualisation has likely made individual resources more important for the maintenance of social ties. This raises the question whether lower-educated adults are more disadvantaged in later-born cohorts in personal network structure and function. Observations are from 4,886 individuals aged 55 and over from the Longitudinal Aging Study Amsterdam (LASA), who are followed over a timespan of a maximum of 24 years between 1992 and 2016. Multi-level regression models are estimated to determine cohort differences. Network size is larger in later-born cohorts, and more so for the higher-educated than for the lower-educated adults. Network diversity increases across birth cohorts irrespective of educational level. Lower- and higher-educated women, and lower-educated men give more instrumental support in later-born cohorts, whereas higher-educated men do not show such a steep increase. More emotional and instrumental support is also received in later-born cohorts irrespective of educational level, but higher-educated adults receive more emotional support in all birth cohorts. Thus, lower-educated older adults are not necessarily worse off socially in later-born cohorts. Instead, they are even more likely to be active givers of support. Also, most of the gains in personal networks of older adults in later-born cohorts are independent of educational level, suggesting that the social landscape for older adults today is much richer.
