What are the hallmark characteristics of each stage in the Demographic Transition Model? (Select the sequence that matches Stage 1 through Stage 4; Stage 5 is a potential decline.)

• A. Stage 1: high birth and death; Stage 2: falling death; Stage 3: falling birth; Stage 4: low birth and death; Stage 5: potential decline
• B. Stage 1: high birth and death; Stage 2: birth rate rises; Stage 3: death rate rises; Stage 4: population declines
• C. Stage 1: low birth and death; Stage 2: falling death; Stage 3: rising birth; Stage 4: high birth and death
• D. Stage 1: low birth; Stage 2: high death; Stage 3: high birth; Stage 4: high death

Answer: (A)

The key idea here is how birth and death rates shift as societies develop, forming a four-stage pattern (with a possible fifth) called the Demographic Transition Model. In Stage 1 both birth and death rates are high, which keeps population growth slow. In Stage 2 the death rate falls quickly because of better health, sanitation, and nutrition, while births stay high, so the population grows rapidly. In Stage 3 birth rates begin to fall as urbanization, education (especially for women), and access to contraception influence family size. Death rates remain low. In Stage 4 both birth and death rates settle at low levels, leading to a stable or very slowly growing population. Some models add Stage 5, where birth rates fall below death rates, causing a potential population decline. The sequence described matches that progression, making it the best fit. The other options misstate these trends—for example, suggesting birth rates rise in Stage 2, or that Stage 1 has low birth and death, or that Stage 4 features high death—none of which align with how the model describes development-driven changes in fertility and mortality.
