The phenomena of mobility and migration are growing as more people
move and frequently change their residences – intra-nationally, transnationally
and internationally. Traditional conceptualisations of nation-state
borders used to be the contextual prerequisite for “citizenship”, but this is
currently being challenged. National borders are no longer a comprehensive
conception that can be used to understand and manage “citizens”. The
sociologist John Urry coined this phenomenon “The post-societal agenda
of the world”, because national borders are no longer natural borders (Urry
2000). Another sociologist, Peggy Levitt, further suggests that migration
should be studied as transnational social fields, and not as “natural containers”
of delineated national social fields (Levitt 2007). In this chapter,
the focus is on the consequences of Danish national migration policies
related to transnational social fields, which Danish retired migrants enter
while moving to warmer climates in Southern Europe
