Wangari is from the Kikuyu word for "leopard" in the totemic clan system of the Kikuyu people of Kenya. Wangari Maathai (1940-2011) was the Kenyan environmental and political activist who founded the Green Belt Movement, planting over 30 million trees across Africa.
Wangari does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Wangari reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
