Migration and demographic alterations have challenged the dynamics to the Baltic states, particularly within the lens of pre and post- EU transition periods. Before their European Union (EU) accession, the Baltics experienced an outflow of highskilled migrants, drawn westward by prospects in education and elevated job opportunities, leading to a discernible "brain drain." Then, accession coincided with the economic crisis and after EU accession, this pattern shifted dramatically. A surge in both low and high-skilled migrants was observed, the scale of which eclipsed pre-EU numbers. It was not only the young, an intriguing trend emerged with the older Baltic demographic, or 'senior migration,' journeying abroad, driven by the need for more income, and recognition in the labour force and society. This escalation brought about intricate challenges: from the emptying of the countryside, aging and shrinking population, and growing diaspora. Concurrently, the Baltics grappled with dwindling birthrates, intensifying the urgency for nuanced public policies to mitigate an impending demographic crunch. A pivotal dimension of this migration narrative is the phenomenon of return migration. Some Baltic expatriates, enriched by global experiences, began reorienting homeward. What we observe is that all Baltic countries implemented policy changes to increase the birthrate and attract return migrants, but their position on attracting migrants from elsewhere differed remarkably. In this presentation, we offer insight into the Baltic migration saga, from brain drain concerns to demographic shifts. It accentuates the indispensable role of informed public policies, which while addressing immediate migratory challenges, also strategically navigate the long-term demographic transformations, safeguarding the region's future prosperity,
