Zlata is the Slavic word for "golden" — used as a feminine name in Russian, Croatian, Serbian, Bulgarian, and Czech.
Zlata Filipović (born 1980) is the Bosnian author of Zlata's Diary — the war diary of an 11-year-old during the Siege of Sarajevo.
Zlata 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 Zlata reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
