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.

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
