Important note for anyone that doesn't already know, migrant in this context refers to internal migration from far off home towns as opposed to "immigrant" in the context of temporary farm labour migrant workers migrating in from another country where such work forms part of their visa arrangements (Australia's migrant worker visas, pick some fruit, do some backpacking) or is part of seasonal regional migration over the border such as parts of the USA where Mexican workers legally migrate on short temporary work visas during farm's harvest seasons.
