The Portuguese Migration Observatory (OM) has called for increased public investment and integration of migration data into local policymaking, particularly in inland municipalities experiencing rapid growth in immigrant populations, naming a responsibility “to prevent social risks”.
In a report published today on the “implications for territorial cohesion, public policies and migration governance”, the body, which operates under AIMA (Agency for Integration, Migration and Asylum), warns that patterns of settlement in Portugal’s interior are changing and require new responses from the Government, local authorities, and public services.
The Algarve is identified as a region under strong migratory pressure, where two distinct profiles coexist: economic migrants and “foreign residents who are retired or economically independent”. This situation, the report says, increases “pressure on the housing market” and “deepens social inequalities while intensifying processes of socio-spatial segmentation”.
It stresses that it is “essential to strengthen the institutional capacity of municipalities experiencing strong growth in foreign populations”, alongside enhanced “labour inspections” and the provision of “decent housing and transport” for these communities.
The authors of the report argue that migration data should also be integrated “in real time into health, education and housing planning”, rather than the current “lack of coordination between statistical production, planning and decision-making”, which they say “significantly limits the responsiveness of public policies”.
The report warns of “the overburdening of local public services, the precariousness of migrant labour in rural areas and the intensification of social tensions linked to residential segregation” as key risk factors. It adds that the “absence of public responses adapted to this new migratory geography may exacerbate territorial inequalities, weaken social cohesion and undermine local governance capacity across multiple regions”.
In 2024, the foreign resident population in Portugal, estimated at 1,543,697 people, was recognised as having “ceased to be concentrated exclusively in major metropolitan areas”. This “new migratory geography”, the report notes, reveals a growing dependence on foreign labour in sectors such as intensive agriculture, tourism, industry, logistics and care services, while also helping to mitigate depopulation and demographic ageing across large swathes of the interior.
For this reason, the authors, led by sociologist Pedro Góis, propose “a set of structural measures”, including strengthening municipal institutional capacity, territorially differentiated policies, the integration of real-time data into public planning, combating disinformation, and enhanced cooperation between countries of origin and destination, which they describe as essential to ensuring “more effective, equitable, and sustainable migration governance”.
In recent years, in these “low-density territories”, immigrants have moved beyond a merely complementary role and now play an “absolutely structural function in sustaining local economic activity”.
Migrants have helped to “mitigate depopulation processes, reactivate services, keep schools open, and sustain local economies that, in the absence of immigration, would be at risk of functional collapse”, the report states.
However, this “new migratory cycle” poses challenges for public policies that “remain largely anchored in an urban–metropolitan model of reception and integration”, revealing difficulties in responding to the growing presence of immigrants in inland areas and the administrative fragility of many low-density municipalities.
Without “robust coordination between migration policies, territorial development policies, and housing, health, education and employment policies”, the authors warn, the risks of labour precariousness, residential segregation and social tensions will increase.
Despite this, in absolute terms, migratory pressure remains most visible in the metropolitan areas of Lisbon and Porto, with the capital home to more than 200,000 foreign residents, followed by neighbouring commuter-municipalities, largely as a result of the housing crisis.
According to the report, the Alentejo, particularly municipalities such as Odemira, Ferreira do Alentejo, Beja and Serpa, has become a central territory for super-intensive agriculture and agro-export production, “deeply reliant on the use of migrant labour”.
Meanwhile, the central and northern interior regions are witnessing the “repopulation of ageing and depopulated territories”, with low-density municipalities increasingly integrating foreign workers into elderly care, small-scale agriculture, restaurants, retail, and public services.
However, the authors caution that the “limited administrative and technical capacity of many of these municipalities restricts their ability to respond in areas such as integration policies, housing, health and education”, stressing that this diversity requires “solutions tailored to the scale and specific characteristics of each territory”, particularly where the proportion of foreign residents has significantly altered the social fabric.
“Cases such as Aljezur, Vila do Bispo, Monchique, Idanha-a-Nova and Vila Nova de Poiares, among others,” the report notes, are “true guinea-pig territories of migration policy in Portugal, where both the positive effects and the risks associated with immigration are manifested more intensely and immediately”.
Chronic public underinvestment in smaller municipalities, combined with the “additional pressure arising from new migratory demand”, has “exposed structural weaknesses and fuelled local perceptions of competition for scarce resources, with potential effects on social tension”.
This is compounded by the precarious working conditions often faced by migrants in rural and peripheral areas, exacerbated by the “lack of regular inspections, dependence on intermediaries and limited access to information”, increasing their vulnerability to “situations of labour exploitation, human trafficking, and substandard housing”.
Lastly, the report highlights the “growth of social tensions linked to residential segregation and the spatial concentration of poverty”, often in “areas with cheaper housing that is frequently degraded or overcrowded”, which may “fuel narratives of rejection, stigmatisation and symbolic conflict”.
