Question

The ratio between total population and net cultivated area is known as __________

• A. Agricultural density
• B. Physiological density
• C. Economic density
• D. Arithmetic density

Hint:

Remember the density measures: \[ \boxed{ \begin{aligned} \text{Arithmetic Density} &\rightarrow \frac{\text{Population}}{\text{Total Land Area}}, \text{Physiological Density} &\rightarrow \frac{\text{Population}}{\text{Arable Land}}, \text{Agricultural Density} &\rightarrow \frac{\text{Farmers}}{\text{Arable Land}}. \end{aligned} } \] Mnemonic: “Physiological = People on Productive (Arable) Land.”

Answer 1

The Correct Option is B

Concept: Physiological density is the ratio of the total population to the net cultivated (arable) land area. It indicates the pressure of population on productive agricultural land.

Step 1: Recall the definitions. \[ \begin{aligned} \text{Arithmetic Density} &= \frac{\text{Total Population}}{\text{Total Land Area}}, \text{Physiological Density} &= \frac{\text{Total Population}}{\text{Net Cultivated (Arable) Area}}, \text{Agricultural Density} &= \frac{\text{Agricultural Population}}{\text{Net Cultivated Area}}. \end{aligned} \]

Step 2: Identify the required density. Since the ratio is between total population and net cultivated area, \[ \boxed{\text{Physiological Density}} \] Hence, \[ \boxed{\text{(B)}} \]
