Registered voters · 2017 to 2027

  2. 2022 86,986
  3. 2027 none held yet

No 2027 register is held for this constituency yet. The bar fills in when IEBC publishes one and it is loaded; nothing here is projected forward — IEBC de-duplicates, audits and gazettes a register before it counts.

Between the registers held · 2017–2022

+6,256 voters added 232nd of 290 constituencies by number
+7.75% growth on the 2017 register 244th of 290 constituencies by percentage
How this is worked out

Both figures compare the same constituency in the two registers we hold. Percentage change = (2022 count − 2017 count) ÷ 2017 count × 100. Ranks cover only constituencies with a register in both years. These are registrations, not votes cast.

Bars are scaled against the largest register this constituency itself holds, and start at zero. A year with no register held shows no bar rather than a zero.

What these numbers don’t measure
Committee work
Parliament publishes no committee attendance for either House, so nobody can count it — us included.
Constituency work
Funerals, harambees, schools, casework. Recorded nowhere we can read.
Whether it worked
We can count questions asked, not answers given.
Speaking often isn’t speaking well. Use these to ask Kiambu better questions — not to grade them.
