safety in numbers
The idea that one is less likely to be harmed while in a group than by oneself. Don't go into the city alone at night—there's safety in numbers.
safety in numbers, there's
A group has more protection against harm than an individual, as in Her parents won't allow her to date but do let her go to parties, saying there's safety in numbers . This phrase comes from the Latin proverb, Defendit numerus, presumably alluding to a military situation. It was first recorded in English about 1550.
