Today I was searching for a word that I'm fairly certain exists, but I can't find evidence of anywhere. I wanted to refer to a segment of the population, and I used the word "constituency" to describe a specific group of people. Apparently, this word has a specifically political context, e.g. "The senator's constituency voted him back into office."
Is there a word, specifically a word that sounds like constituency or contingency, that describes what I'm looking for? That is to say, a word that describes a segment of the population sans a political context.
