As a girls' name, Amari first entered the US top-1000 in 2008 and the top-500 in 2014; it appears in both the boys' and girls' lists for the past decade. Amari Cooper (born 1994) — American NFL wide receiver; selected 4th overall in the 2015 NFL Draft by the Dallas Cowboys; five-time Pro Bowl selection; one of the most-decorated NFL receivers of his draft class (male reference, but the name is unisex). Amari Bailey — male basketball player. Amari is also the Sanskrit word amari ("eternal"), giving the name a parallel use in Hindu-Indian families.
Amari 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 Amari reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
