emigration or increase in death rate
emigration or increase in birth rate
immigration or decrease in death rate
immigration or increase in birth rate

emigration or increase in death rate

Explanation:

emigration is leaving ones place of living, which would explain why the population is going down, and an increased death rate means more individuals are dying than the birth rate can keep up with, so the population would be going down as well. so, the answer is number one.

performances and sculptures
