Methodology & sources

Age structure: KNBS 2019 Census (via OCHA COD-PS, data.humdata.org/dataset/cod-ps-ken), from the 2019 census county tables (KNBS via OCHA).
Registered voters: IEBC 2022 General Election register (per ward), the same figures behind every seat page here.
2027 projections age the census cohorts forward to August 2027 (whoever was N years old in 2019 is N+8), ignoring mortality and migration; treat them as estimates.
Gen-z = born 1997-2012; those born by August 2009 are eligible in 2027. Constituency and ward figures apply the county's age share to the seat's registered voters.
These are eligibility and registration figures, never turnout predictions.
