Yogyakarta is projected to be the most loneliness-prone city in Indonesia in 2025.

Kompas R&D released a list of cities most vulnerable to loneliness in Indonesia in 2025.

Overall, 1 in 5, or 19.97% of respondents in Indonesia, admitted to feeling lonely at least once a week.

"Without serious intervention, loneliness can trigger mental disorders, increase the risk of heart disease and diabetes, decrease productivity, and even lead to suicidal thoughts," Kompas R&D wrote in its report on Wednesday (July 30, 2025).

This research was conducted in 30 Indonesian cities selected based on criteria of a population exceeding 100,000 people and a density of over 4,500 people per km².

The index was compiled using 12 variables, including the percentage of one-person households, the proportion of elderly residents, the unemployment rate, the availability of public spaces and sports facilities, healthcare services, and marital status.

Notably, this index does not directly measure individual feelings but rather a city's vulnerability to loneliness based on demographic and infrastructural factors. The higher the score, the higher the vulnerability of its residents to feeling lonely.

As a result, Yogyakarta was recorded as the city with the highest national loneliness vulnerability index score, reaching 74.94 points in 2025.

"Yogyakarta's high score in the index is attributed to the high proportion of one-person households (OPH), related to the large number of boarding students and elderly residents," Kompas R&D wrote.

Below is a list of the 10 cities with the highest loneliness vulnerability index in 2025, according to Kompas R&D:

1. Yogyakarta: 74.94 points
2. Central Jakarta: 65.61 points
3. Makassar: 54.43 points
