Minang is from the Indonesian Minang (short for Minangkabau) — ethnic group of West Sumatra Indonesia. Minang refers to the Minangkabau people — widely considered the world's largest matrilineal society (approximately 7 million Minangkabau people) where property + clan names pass through the maternal line + women hold central social authority. The Minangkabau diaspora (merantau tradition) has spread Minang culture across Sumatra, Java, Malaysia, Singapore + the Padang cuisine (rendang) UNESCO-acknowledged World's Best Food.
Minang 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 Minang reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
