What measure of migration tells whether more people are entering or leaving a country?

I believe the answer is: Net migration rate

Net migration rate refers to the difference betweeen the number of people that come into a certain area and the number of people that leave that area within the period of one year. When the number of people that come in is larger, the net migration rate is considered to be positive, and when the number of people that come out is larger, the net migration is considered to be negative.

explanation:

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).
