I'm learning about demand in my economics class and we're talking about market demand curve. it says that its a summation of all individual demand curves. i'm just wondering if they're actually talking about individuals (as in a single person) vs the whole world or country? sorry if you can't understand the question this was the best way i could think of phrasing it.
