Show me a list that has the 42 tribes. I actually tried to look for something like that years back and I couldnt find anything that made sense. There is nothing like that.
This is another statistical myth like the shortage of 500k units that kenya is said to exprience or the half million kibera largest slum in the world until 2010 census proved this to be a fallacy....these myths are all over the world. This guy article and research shows that the 42 tribes are a fallacy
I'd go with the latest census. There might be questions about number of tribes, but not in any serious sense. In fact the only doubts I can recognize as significant are about whether tribes like Luhya, Mijikenda etc constitute one tribe. In case you break them apart, you have a handful more tribes added to the 40 something baseline.
Here is 1969 census.. It has the list but tribes are more than 42
http://statistics.knbs.or.ke/nada/index.php/catalog/64/datafile/F1/V8In multiple interviews with various government officials I was repeatedly told there were 42+ tribes, but nobody could tell me the nature or location of the list. “Do you know?” one official asked me. Ten years earlier, I had asked members of the minority Nubian community too: “Forty-two tribes. And we will be the 43rd.” They even had a letter from a Minister declaring they would, indeed, be counted as such in the 2009 census. But I struggled to find the list. Who is on it? Does it even exist? And if so, who controls it, and how? Why does nobody know? And does it matter? In my research, this idea of “the 42” kept coming up over and over again. I have been conducting academic research in Kenya since 2009, mostly with the minority Nubian community which has long sought recognition as Kenyan, and has had considerable success in recent years in getting it. It was my first interviews with Nubian elders in 2009 that made me start wondering about this idea of “the 42”, where it comes from, why it matters.
