The twenty-first century will be the century of the migrant. At the turn of the century, there were more regional and international migrants than ever before in recorded history.1 Today, there are over 1 billion migrants.2 Each decade, the percentage of migrants as a share of the total population continues to rise, and in the next twenty-five years, the rate of migration is predicted to be higher than during the last twenty-five years.3 It has become more necessary for people to migrate because of environmental, economic, and political instability. Climate change, in particular, may cause international migration to double over the next forty years.4 The percentage of total migrants who are non-status or undocumented is increasing, which poses a serious challenge to democracy and political representation.5
