Answer 3

Migration means something else entirely to me. When I hear the word I do not think of permanent immigration or emigration but of the old as the human race tension between settled city and town and farm dwellers and tough herders and hunters following the seasons and their game from mountains to prairies. The settled people usually were ruled by invader migrant people who then civilized until the next band of migrants took over. One life style ate grain, the other milk and meat from the horses, buffalo, reindeer or whatever. They migrated because of seasons mostly, for water, grass, fish, etc. Present day migrant workers often follow crop harvest seasons north and south.
