Final answer:
Physiological population density is a superior measure because it reflects the number of people per unit area of arable land, showing the carrying capacity and potential for food production, unlike simple population density.
Step-by-step explanation:
Physiological population density is considered a superior measure over simple population density because it provides a more realistic view of how many people are living in an area that is actually available for human use, such as arable land. It does not measure the physical characteristics of individuals but rather the number of people per unit area of arable land.
This is an important distinction because physiological population density takes into account the carrying capacity of the land and the potential for food production, which can be a critical factor in understanding population pressures on resources and the environment. It helps to provide insights into the degree of urbanization, agricultural potential, and the complexity of a region's infrastructure and resource management.
