Somalia had 3 million approx in the 80's
(100,000 / 3,000,000) x 100 = 3.34%
They're claiming 3% of Somalia's entire population died let alone those who got injured or displaced.
Furthermore, around this period, Isaaq were around 600,000.
(100,000 / 600,000) x 100 = 16.67
They're claiming 1/6 of their population died in 1988.
I don't think math is a secessionist's strong point.
