NATO public opinion research
- English
- French
NATO runs a programme of public opinion research in all countries across the Alliance to inform organisational decision-making, strategy and planning. Using nationally representative surveys, NATO tracks respondents’ opinions about the security environment as well as key metrics. These include support for defence spending, and for core NATO principles such as collective defence and the transatlantic bond. As an alliance of democracies, NATO derives its legitimacy from the ongoing support of its member countries and their populations.

- NATO has been interested in public opinions in its member countries since the Alliance was founded in 1949. Over the years, NATO has conducted various surveys and polls to measure support for the Alliance and its policies and principles. The current programme of public opinion research has been running since 2019.
- Alliance-wide surveys are run twice annually, in April-May and November-December.
- Data from the November-December surveys is published on an annual basis in conjunction with the Secretary General’s Annual Report, released in March.
- April-May survey findings have been published ahead of the 2021 Brussels Summit, 2022 Madrid Summit, 2023 Vilnius Summit and 2024 Washington Summit.
- Research data is shared across all NATO entities to support evidence-based decision-making. Charts and data tables are released to the public as a transparent, statistically reliable resource on public perceptions relating to the security environment.
Most recent survey findings
NATO polling ahead of the 2024 Washington Summit
The most recent public opinion research took place in April-May 2024, ahead of the 2024 NATO Summit in Washington, D.C.

A majority of Allied respondents continue to agree that their country should defend a NATO Ally if attacked (63 per cent) and 70 per cent would vote for their country to remain a NATO member in a referendum. Support for increasing defence spending continues to rise (41 per cent) for the fifth consecutive year, and 76 per cent of respondents support maintaining or increasing defence spending. A majority of respondents also continue to agree that their country should provide support to Ukraine (61 per cent) as it defends itself against Russia’s war of aggression.

Historical context
NATO has been interested in public opinion in its member countries since its foundation in 1949. On 18 May 1950, the North Atlantic Council issued a resolution in which it committed itself to: "Promote and coordinate public information in furtherance of the objectives of the Treaty while leaving responsibility for national programs to each country...".
To improve understanding of NATO and increase public confidence in its ability to defend its people, the Alliance created the NATO Information Service in August 1950. Working in conjunction with member governments, the Information Service explained NATO’s purpose clearly to Allied citizens, helping them understand what NATO actually does. It also sought to help the public become more resilient to manipulation from Soviet propaganda and disinformation, which were designed to have a corrosive effect on the solidarity and cohesion of Allied societies, and ultimately weaken the Alliance and its members.
The Information Service’s successor bodies – including today’s Public Diplomacy Division – have carried on the vital tasks of informing the public of NATO’s activities and maintaining transparency. Assessing the opinions of the public is a crucial component of this work. Understanding what people know and believe about NATO helps the Alliance identify the areas where it needs to do a better job of explaining its work. It also helps NATO make evidence-based decisions and plans for the future. Over the years, NATO has conducted various surveys and polls to measure support for the Alliance and its policies and principles. The current programme of public opinion research has been running since 2019.
