Citra is the Indonesian word for "image" — from the Sanskrit citrā (variegated, brilliant).
Citra is widely used in Indonesia. The Citra Award is Indonesia's top film prize, named after the goddess.
Citra 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 Citra reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
