- Stage 1: High birth rate and high death rate (pre-industrial society, population remains stationary/slow-growing).
- Stage 2: High birth rate and declining/low death rate due to advancements in healthcare, sanitation, and food supply (population explosion).
- Stage 3/4: Low birth rate and low death rate (industrialized society with family planning and urbanization, population stabilizes). Thus, the correct developmental sequence is 2 -> 3 -> 1.
