Which city has the loneliest residents? A new international study analysed the loneliness index of 25 major cities to find the answer.

The World’s Loneliest Cities Index 2025 was compiled by Nova Tech Industries, mapping which cities report the highest levels of social isolation. The list evaluates 25 global metropolises using nine different factors, including access to healthcare, availability of communal spaces, social activity options, and how open and welcoming locals are.

European cities lead the pack as the least lonely

European cities clearly dominated the top tier of the rankings, with ten of the 14 European cities surveyed landing in the upper half. This is largely due to standout performances in several categories:

  • European cities scored highest for access to healthcare
  • Pedestrian-friendly urban planning encourages social interaction
  • Cultural traditions that prioritise community life and social bonds

Cologne topped the list with 41.8 points. In addition to a strong healthcare system, the city boasts public spaces and institutions designed to foster social engagement. Local leadership has long prioritised infrastructure that supports interpersonal connections, which may explain why residents feel less isolated.

Lisbon followed closely, trailing by just a tenth of a point. The Portuguese capital’s Mediterranean vibe, traditionally strong family ties, and vibrant street culture help make socialising easier and community life more accessible.

Miami also scored 41.7 points, tying for second place. Notably, it’s the only American city to make the top ranks. Its multicultural population, coastal lifestyle, and constant buzz help counteract the social isolation that plagues many other U.S. urban centres.

Barcelona secured fourth place with 41.5 points. Community events and a rich cultural scene are part of daily life in the Catalan capital, which also benefits from a traditionally strong social network.

Rounding out the top five is Vienna with 40.9 points. The Austrian capital consistently ranks among the world’s most livable cities thanks to its robust social infrastructure and people-focused urban planning, both of which contribute to a lower sense of isolation among its residents.

Budapest ranked 17th with 32.3 points.

German cities performed particularly well, claiming four of the top ten spots. Cologne, Berlin, Hamburg, and Munich all benefit from strong welfare systems, exceptional healthcare, and a balanced approach to urban living and social infrastructure. These are considered the most effective tools for combating loneliness in urban areas.

New York named the world’s loneliest major city

Surprisingly, New York (one of the world’s busiest cities) finished at the very bottom of the list. Los Angeles, Houston, San Diego, and Dallas also ranked at the lower end. Despite their dense populations and constant hustle, residents of these cities often feel socially isolated. In megacities, crowds don’t necessarily translate to connection.

Loneliness is now a public health threat

In 2023, the World Health Organisation officially declared loneliness a global public health issue. Chronic isolation doesn’t just affect mental well-being: it increases the risk of cardiovascular disease and even dementia. According to the WHO, about 16% of the global population suffers from loneliness, which is linked to nearly 900,000 deaths worldwide each year.

Opportunities for Budapest

While Budapest’s mid-tier ranking highlights areas for improvement, it also points to potential ways to strengthen community ties. The Hungarian capital already boasts a rich cultural calendar, festivals, and major tourist attractions, but the data suggests there’s room to enhance everyday social life. By investing in more public gathering spaces, easily accessible social programs, and inclusive initiatives that engage diverse groups, the city could not only boost residents’ morale but also improve overall quality of life.
