Which of the following factors is one of two that is usually most responsible for determining population growth? total number of people within a continent average number of people in a given area world's total population average weight of people in a given area

I would say something along the lines of socioeconomic status and the population density. meaning if you have an area with a community of people that are pore (mainly to pore to afford contraceptive methods) and there are a lot of them in a small area the population will grow faster. if your thinking more along the lines of animals then you might want to consider food availability and predator prey ratio.
