>1% Indian population last time I checked.
"There are over 75,000 people of Indian origin including Indian passport holders (about 0.36 percent of total population). Indians handle between 30-35 percent of total economy. Of these, about 75% are Kenyans citizens, 10% are British overseas citizens and about 15% are Indian citizens (NRIs). "
However, segregation between "Asians" (Indian, Goans, Pakistanis) and Black Kenyans is even more pronounced than it was between whites & Negroes in the South during the first half of the 20th century.
It is highly unlikely that there was intermarriage in his father's ancestry.
Thanks for the data.
