From July 23 to August 4, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey "Omnibus", to which, on its own initiative, added questions about the perception of individual peace plans to end the war. By the method of telephone interviews (computer-assistedtelephoneinterviews, 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), 1,022 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 a sample of 1022 respondents (with a probability of 0.95 and taking into account the design effect of 1.3) does not exceed 4.1%. At the same time, for the peace plans considered in this press release, an experiment was implemented and we learned the opinion of respondents about one of three randomly selected peace plans (to avoid the effect of the order of responses). Each peace plan was evaluated by 324-351 respondents, which gives an error (with a probability of 0.95 and taking into account the design effect of 1.3) of no more than 7.2%.

Under 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 July 23 to August 4, 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 trust in President V.

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%.
