Votes and Immigration: How Demographics Might Change French Politics

In an interview with the daily newspaper Le Figaro, Nicolas Pouvreau-Monti, director of the Observatory of Immigration and Demography, a think tank established in 2020 and specialising in the statistical analysis of migratory phenomena, offers an original and relatively novel approach to the migration debate in France: rather than merely measuring the impact of immigration on the economy, public finances, education, or social cohesion, he analyses its effects on the country’s electoral landscape. Whereas research on immigration generally focuses on budgetary, cultural, or security issues, the author seeks to show that the country’s demographic transformation is now producing direct and lasting political consequences.

According to him, France now has around 7.5 million potential voters with an immigrant background, that is to say, naturalised immigrants or descendants of immigrants who have acquired the right to vote. His central argument is that the migratory trends of recent decades have not merely altered the social composition of the French population but also the structure of the electorate. Thus, debates on immigration can no longer be approached solely from an economic or identity-based perspective: they have also become a matter of electoral sociology and the transformation of the democratic landscape.

His analysis is based on extensive statistical work involving the cross-referencing of demographic, territorial, and electoral data. In particular, he seeks to establish correlations between the presence of populations of immigrant origin and certain voting behaviours. In several urban areas with a high concentration of non-European immigrants, he observes a significant increase in support for the radical Left, particularly for Jean-Luc Mélenchon in the 2022 presidential election. Pouvreau-Monti has identified very strong correlations between the proportion of young people from immigrant backgrounds and La France Insoumise (LFI)’s electoral results in certain areas, such as Seine-Saint-Denis or several districts of Marseille. This is where the famous ‘New France’—so dear to LFI—begins to take shape, a movement that exploits the distinctiveness of immigrants for electoral gain, whereas, in the past, political forces—including the Communist Party—played the opposite role, acting as forces of integration for European immigrants, whether Italian, Polish, or Spanish. Conversely, while support for the Rassemblement National (RN) is growing significantly across all sections of the population, it is increasing only marginally among voters from immigrant backgrounds.

The interview also emphasises the cumulative and lasting nature of this trend. For Pouvreau-Monti, the demographic shifts observed over several decades are now beginning to have large-scale political effects. The children and grandchildren of immigrants from the 1980s, 1990s, and 2000s are now reaching voting age. This means that past migration flows are gradually altering the composition of the French electorate, with consequences likely to be felt across several generations.

The author also highlights that this electoral realignment could exacerbate certain regional divides. Major cities and urban areas with high concentrations of immigrants are likely to evolve differently politically from more rural areas or those less affected by immigration. This dynamic would contribute to reinforcing an already visible polarisation between areas won over by left-wing or multiculturalist parties and other regions more receptive to identity-based or sovereigntist rhetoric. Immigration would therefore no longer be merely a subject of political debate: it would become a defining factor in the electoral contest itself.

This analysis forms part of a broader initiative led by the Observatory of Immigration and Demography. The organisation states that it aims to make data accessible that is often scattered or under-utilised in public debate. Its work has met with a growing response in some media outlets and amongst a section of the French Right, notably because it addresses aspects of the migration phenomenon that have been little studied to date. 

Unsurprisingly, Pouvreau-Monti’s analyses have also drawn criticism from the Left and the academic world. The main objection centres on an argument frequently used on the Left: the observation of correlations (in this case, between immigration and voting behaviour) should not be sufficient to establish direct causality; it would be necessary to incorporate more social, economic, or geographical variables to explain voting patterns. But these objections do not stand up to the facts, as Pouvreau-Monti demonstrates with specific, concrete examples: an opinion poll shows that 59% of Muslims in the higher socio-professional categories say they intend to vote for Jean-Luc Mélenchon in 2027, compared with 58% of Muslims in the lower socio-professional categories. Here, “the strictly economic explanation seems to give way to other variables, including migrant or religious background.”

These arguments have also been put forward to discredit the website Où va ma France, which analyses local areas through a whole range of intersecting criteria that political correctness, as a matter of principle, forbids from being linked—such as, for example, the concentration in a neighbourhood of first names of African or North African origin among newborns and the crime rate.

The fact remains, however, that the observatory’s work opens up particularly stimulating avenues for reflection and debate. As voting is intended to shape the policies of tomorrow, the perspective has to shift: to what extent will immigration now determine, at the ballot box, our fate for years to come?
