The first option describes determining how many people live in a certain unit of area, which matches the definition of population density calculation. The second option is about carrying capacity, the third is about measuring land area (not population density calculation), and the fourth is about population change over time, not density.

The correct option is: They determine how many people live in a certain unit of area.
