<prompt> Human: Whenever I take a calculator like this: or thisI notice that they always include a lot of money for housing. At first I thought they meant daycare, but then I see that is in a separate category. I already have a house and dont need to buy a new separate house for my child, so Im confused at to why that category is always included in calculators. The only thing I could think of is that you need a bigger house to accomidate more children, but I dont think the difference in how much you spend on housing is that great. They suggest that it will cost 8K per kid per year in housing!  <response>: The difference in housing can be VERY expensive, depending on area. A single person or a couple can live in a small one bedroom apartment or even a studio. A family with a small child or two probably wants more space
