Final answer:
Stage 4 of the Demographic Transition Model is characterized by developed societies with low birth and death rates, resulting in slow or stabilized population growth.
Step-by-step explanation:
The stage characterized by developed societies where both birth and death rates are low, and population growth is slow, is Stage 4. This is the stage in the Demographic Transition Model (DTM) where population growth stabilizes as the birth rate has declined to match the low death rate that was characteristic of the earlier stage. At this point, societies are highly developed with widespread access to healthcare, contraception, and education, leading to a balance between mortality and mortality rates.
In this stage, societies demonstrate stable population numbers with only modest growth if any, reflecting a transitioned society that has gone through the significant changes of the earlier stages—from high birth and death rates in Stage 1 to declining death rates in Stage 2, followed by declining birth rates in Stage 3.
