Final answer:
A low arithmetic density means that an area has a few people per square mile.
Step-by-step explanation:
A low arithmetic density means that an area has a few people per square mile. It indicates that the population in that area is relatively small. For example, in Bangladesh, the physiologic density is more than 5,000 people per square mile, while in Sri Lanka it is more than 6,000 people per square mile. These high densities indicate a larger population, whereas a low arithmetic density would mean a smaller population.
