the aswer would be true

Answer 2

your comment is correct: yes, Italy, but not Niger has an aging population and Italy has a high life expectancy while Niger does not.

As for your question in comments: Stage 1 and 2 countries have a very high birth rate, which means that they have a growing population, so people will rather emigrate from it than to it- so the statement is correct.
