1) Everyone last yr turn out impressively at 85%...in that sense turn out is now evening out.
2) Registration is i think the problem for CORD allied communities...assuming IEBC projection of adults were accurate.
3) GEMA population are transitioning...less kids...more adults. In place like NEP or Norther kenya..you have more kids than adults.
4) Generally in kenya...at least 60% of population i think are under 18yrs.
5) Kikuyu pop has dropped from 22.5%(89 census) to 20%(99 census) to 17.5%(09)...by 2017..that will be nearly another 10yrs..so basic progression...kikuyus population will be 15%...today i can wager they're 16.5% of kenya...luhyas are 14.5%.
6) I do not have meru and embu numbers off head...but i would place them combined at about 5-6%(09 census)
In short GEMA demographic domination is definitely coming to an end....this mostly due to low births and immigration outside kenya...while communities like maa,somalis and others are in midst of baby boom...typical somali family now has 10-15 kids per woman....in central..you're talking 3 kids on average.
The upside GEMA will reap from demographic dividend..that mean more working adults feeding less mouths (under 18yrs and over 65yrs)...therefore people will be able to save more..and will stop living from hand to mouth....so more wealth.
RVP: Wrong! This guys turn out 90% plus. You need to rething your numbers. I do however trust your judgement. I will look at at what you are saying. If what you are saying is correct, assuming that all other dynamics stay the same, The Luo or Luhya could be a game changer. You are talking of a 5% margin. I stand corrected.
