Salam is from the Arabic Salām (سلام — peace, safety). Salām is one of the 99 Names of God in Islam (As-Salām, Source of Peace) + central to the Islamic greeting As-salāmu ʿalaykum. Notable bearers: Salam Fayyad — Palestinian economist + Prime Minister of the Palestinian Authority 2007-2013; Salam Pax — Iraqi blogger + Where Is Raed?
Salam 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 Salam reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
