Area: The area of the Universe is infinite.
Imports: None. This is a by product of infinity; it is impossible to import things into something that has infinite volume because by definition there is no outside to import things from.
Exports: None, for similar reasons as imports.
Population: None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is zero, therefore the average population of the Universe is zero, and so the total population must be zero.
Art: None. Because the function of art is to hold a mirror up to nature there can be no art because the Universe is infinite which means there simply isn’t a mirror big enough.
