Researchers from Queen's University Belfast, working alongside the Institute for Economics and Peace (IEP), have released the first Northern Ireland Peace Index (NIPI).
The report indicates that recorded violence and the public's fear of it reached their lowest points since 2019.
Dr Andrew Thomson and Professor Dominic Bryan led the investigation, which was supported by funding from the Economic and Social Research Council (ESRC).
Negative peace, defined as the absence of conflict, improved by 10.7% between 2019 and 2025.
Homicide rates fell by 47.9%, while paramilitary activity dropped by 44.7% during this timeframe.
Positive peace, which measures the institutions and attitudes that sustain society, saw a modest rise of 0.9% over the same period.
Confidence in the justice system declined by 24%, alongside a 34% reduction in research and development spending.
Planning decision efficiency also suffered a 41% drop according to the data.
