A “want” is something that isn’t essential to your survival, but it is something that you really would like to have. Examples of wants include a PS5, a new video game, AirPods, or money to watch a movie with your friends. While we would all love to have these things, we would still be able to survive without them.
A “need” is something that is essential to your survival, and you wouldn’t be able to survive with this. Examples of needs include oxygen, water, food, housing, and clothes. You need oxygen to be able to breathe, and you can’t survive long without food or water. Having clothes is also essential, and having a basic unit of housing provides safety to you.
Hope this helps :)
