Latin America and the Caribbean's political systems are experiencing a gradual institutional decay that rarely manifests as outright democratic collapse but instead hollows out governance from within, the United Nations Development Programme warned in a major new report on democracy across the region.

The UNDP's “Democracy and Development 2026” report, launched on May 11 in Montevideo alongside Uruguay's President Yamandú Orsi, finds that while Latin America remains the most democratic region in the developing world — with more than four in five citizens living under elected governments — accumulated pressures are threatening the long-term sustainability of its political systems. Economic progress, the report concludes, has failed to translate into greater institutional legitimacy.

The data underpinning that assessment are stark. According to Latinobarómetro figures cited in the report, public trust in electoral authorities fell from 47% in 2016 to 34% in 2024, while the share of citizens who consider elections in their country fraudulent rose from 48.5% to 60.6% over the same period. Fewer than half of the region's population say they are satisfied with how democracy functions, and more than 70% believe governments serve particular interests rather than the public good.

"The future of democracy and development will depend on our collective ability to transform pressure into progress without sacrificing human agency or freedoms," said Michelle Muschett, the UNDP's regional director for Latin America and the Caribbean.

The report singles out Latin America as the region having the highest level of political polarisation in the world, recording a value of 3.4 out of 4 on the V-Dem project scale, above Eastern Europe, the Asia-Pacific region and the global average of 2.9. That polarisation, the UNDP warns, has shifted from a disagreement over policies into an identity-based confrontation in which political opponents are perceived as existential threats rather than legitimate rivals.

Organised crime is identified as a compounding factor. The report describes it as a systemic and transnational challenge that extends far beyond security concerns, distorting political representation, financing electoral campaigns and contesting state control over territory. Four of the ten countries with the highest levels of political violence globally are located in Latin America and the Caribbean, according to data from the Armed Conflict Location and Event Data Project cited in the report.

Structural inequality deepens the picture. Although the region's Human Development Index rose from 0.648 in 1990 to 0.783 in 2023, that figure drops by 21% when adjusted for inequality. The wealthiest tenth of the population accounts for nearly 37% of regional income, against 13% received by the poorest 40%.

Digital disinformation adds a further dimension. Social networks have become the primary source of news in almost every country in the region, yet more than 60% of users say they distrust them, a tension the UNDP attributes to the influence of algorithms and artificial intelligence on public deliberation.

In response, the report sets out a renewal framework built around three axes: strengthening democratic quality, starting with the independence of electoral bodies; promoting human development resilient enough to withstand crises and reverse inequality; and rebuilding state capacity to guarantee citizens' rights.
