– The Kenya Life Panel Survey (KLPS) is a multigenerational longitudinal dataset originally
designed to assess the impacts of a school-based deworming programme in Busia
District, Kenya initially implemented in 1998-2001.
– Individuals in the original cohort were students attending one of 75 primary schools in
Busia District in 1998. This cohort of 7527 individuals was later expanded to also
include 5153 biological children of the original cohort members.
– In 2025, members of the original cohort were aged 34 to 45, and second-generation
members were aged 7 to 15. Baseline data were collected from original cohort
participants in 1998-2001, with five rounds of follow-up data collected between 2003
and 2025. Baseline data on second-generation cohort members were collected in
2017-2021, with follow-up data collected in 2023-2025.
– Data include information about education, employment, health, migration, cognition,
and expenditures, among other outcomes. Each follow-up round achieved an effective
survey rate between 80% and 85% of the original cohort. While all original cohort
members resided in rural areas at baseline, considerable migration has led 38% of
them to live in a city by 2023, and some have moved to other countries.
