Step 1
C Life expectancy continues to rise due to better sanitation and healthcare causing a continued fall in death rates.
Answer
As a country transitions from Stage 2 to Stage 3 in the demographic transition model, a significant shift occurs in the patterns of mortality and fertility. During this phase, continued improvements in healthcare and sanitation lead to a decline in death rates, which had previously been high due to infectious diseases and poor living conditions.
Simultaneously, life expectancy rises as a result of these healthcare improvements and better nutrition, which reduces infant mortality rates. Consequently, even as the birth rates begin to fall—often attributed to increased educational opportunities and empowerment among the populace—the overall population growth may slow down but continues to remain positive.
