ProjectLinking childhood to midlife and intergenerational cognitive development: Evidence from the Kenya Life Panel Survey Study IDsspp-2025-0001-v1 Study Title

We utilize the Kenya Life Panel Survey (KLPS), a longitudinal study tracking over 7,000 individuals who attended primary school in Kenya. Individuals were sampled in 1998 for participation in schooling interventions, and have been tracked continuously since then in five survey rounds spanning 25 years.
The first goal of the analysis is to estimate the correlation in individual cognitive performance over long periods of time. We utilize cognitive data collected when individuals were children and also when they were in middle-age. Specifically, in 2000 when the respondents were in early adolescence (age range 12 to 15), detailed data was collected in several different cognitive tests. The same cognitive tests were then collected in 2023 when respondents ranged in age from 35 to 38. We estimate the correlation between cognitive tests scores on each of the tests 23 years apart.
The second goal is to estimate intergenerational correlations of cognitive scores. The most recent KLPS survey round (Round 5) also collected (in 2024-25) the same cognitive assessments with a randomly selected sample of children of the KLPS respondents, who range in age from 10 to 13, overlapping with the age at which their parents were tested decades earlier. This allows us to estimate the correlation between cognitive scores of parents and their children, where we are interested both in the correlation of parents’ current score (in 2023) with their children’s scores, as well as the correlation of the parents’ 2000 scores with their children.
