A population primarily composed of individuals past reproductive age will likely experience a decline in numbers over time. With fewer individuals capable of reproduction, the Birth Rate will decrease, potentially leading to an aging population. This demographic shift can strain resources and social systems, as there may be a higher dependency ratio with more elderly relying on a smaller, younger workforce. Ultimately, the population may face challenges in sustainability and economic vitality.
The population would decrease significantly, and perhaps die out. This is because the birth rate would be small and the death rate would be large. As the "old" individuals die, there will not be enough "babies" to replace them.
