From May 15 to June 3, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey “Omnibus”, to which, on its own initiative, added own questions about the perception of European / US policy towards Ukraine, the perception of D. Trump’s role for Ukraine and the attitude towards the USA / ordinary Americans / US leadership. By the method of telephone interviews (computer-assisted telephone interviews, CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting) in all regions of Ukraine (the territory controlled by the Government of Ukraine), 2,004 respondents were surveyed (about 500 respondents answered the question about the perception of European / US policy towards Ukraine, and about 1,000 respondents answered the other questions). The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived in the territory of Ukraine controlled by the Government of Ukraine. The sample did not include residents of territories temporarily not controlled by the Ukrainian authorities (at the same time, some of the respondents are IDPs who moved from the occupied territories), and the survey was not conducted with citizens who left abroad after February 24, 2022.

Formally, under normal circumstances, the margin of error of a sample around 1000 respondents (with a probability of 0,95 and taking into account the design effect of 1,3) did not exceed 4,1%. the margin of error for the sample around 500 respondents does not exceed 5,8% .

Under the conditions of war, in addition to the specified formal error, a certain systematic deviation is added. Factors that may affect the quality of results in "wartime" conditions were previously cited by KIIS.

In general, we believe that the obtained results are still highly representative and allow a fairly reliable analysis of the public moods of the population.

From May 15 to June 3, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey “Omnibus”, to which, on its own initiative, added a monitoring question about readiness for territorial concessions, and also conducted an experiment on how different interpretations of “territorial concessions” affect the results. By the method of telephone interviews (computer-assisted telephone interviews, CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting) in all regions of Ukraine (the territory controlled by the Government of Ukraine), 2,004 respondents were surveyed (about 500 randomly selected respondents answered each of the 4 versions of questions about territorial concessions). The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived in the territory of Ukraine controlled by the Government of Ukraine. The sample did not include residents of territories temporarily not controlled by the Ukrainian authorities (at the same time, some of the respondents are IDPs who moved from the occupied territories), and the survey was not conducted with citizens who left abroad after February 24, 2022.

Formally, under normal circumstances, the margin of error of such a sample (with a probability of 0.95 and taking into account the design effect of 1.3) did not exceed 2.9%. the margin of error for the sample around 500 respondents does not exceed 5.8% .

From May 15 to June 3, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey “Omnibus”, to which, on its own initiative, added a question about how much more Ukrainians are ready to endure war. By the method of telephone interviews (computer-assisted telephone interviews, CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting) in all regions of Ukraine (the territory controlled by the Government of Ukraine), 1,011 respondents were surveyed. The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived in the territory of Ukraine controlled by the Government of Ukraine. The sample did not include residents of territories temporarily not controlled by the Ukrainian authorities (at the same time, some of the respondents are IDPs who moved from the occupied territories), and the survey was not conducted with citizens who left abroad after February 24, 2022.

Formally, under normal circumstances, the statistical error of such a sample (with a probability of 0.95 and taking into account the design effect of 1.3) did not exceed 4.1% for indicators close to 50%, 3.5% for indicators close to 25%, 2.5% for indicators close to 10%, 1.8% for indicators close to 5%.
