This paper reworks the notion of active ageing through analysis of a case which reverses the retirement-migration nexus – people in the post-socialist realm who approach retirement age and then migrate to begin a new working life. They are thereby introducing a new and complex arrangement to the general concept of ‘international retirement migration’. In the post-socialist world, new retirement migration frontiers emerge in the context of a severe weakening of welfare systems. I illustrate this case with data from long-term research with ageing Latvian migrant women to the United Kingdom and the Nordic countries. Even those whose old-age pensions are more or less adequate nevertheless seek temporary employment and new cultural experiences abroad. However, the dominant trend has been towards the pauperisation of older parents and those approaching retirement age due to the significant decline in state welfare. This case of many older-age Latvians who de facto cannot retire due to low disposable income reveals ‘reverse frontiers of retirement’: working as long as they can, pushing their personal geographical frontiers outward by emigrating for work and making national frontiers more porous through transnational practices. Conceptually and geographically, the research holds relevance for a wider discussion of trends and contextual factors in other post-Soviet and post-socialist countries with increasing diversities among retirees.
