How many people live in a house?

Answer 1

If you are referring to the Houses of the United States Congress, the upper house, the United States Senate, houses 100 United States Senators, and the lower House, the United States House of Representatives, houses 435 United States Representatives.

If you are referring to U.S. Const., Amend. III:

"No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law." (Emphasis added).

"Houses" in this particular context refers to private residences or transient-resident accomodation dwellings of some kind, and not the Houses of Congress.

Understand - there is no Constitutional prohibition on soldiers, or any members of the United States Armed Forces, being present as private citizens in either Chamber of the United States Congress--they are citizens entitled to the same access as any other citizens. There can be lawful restrictions on active members of the military being seated as U.S. Senators or U.S. Representatives, but this restriction refers to holders of "offices under the United States", of which certain positions in the military can be deemed and does not arise strictly because such office-holders might also be active members of the military.

Answer 2

It depends how many people are in the family.
