At the turn of the century there were more migrants than ever before in recorded history. Today, there are over 1 billion migrants. Each decade the percentage of migrants as a share of total population continues to rise and in the next twenty-five years the rate of migration is predicted to be higher than the last twenty-five years. More than ever it is becoming necessary for people to migrate due to environmental, economic, and political instability. What is more, the percentage of
total migrants who are non-status or undocumented is also increasing.
