The nation would most likely have a constrictive population pyramid. This is because the high birth rate 30 years ago would create a larger base (younger age groups) in the pyramid, but as the birth rate has decreased and the population ages, the pyramid would narrow at the younger age groups, reflecting the lower birth rate now.
