From November 26 to December 29, 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 the results of surveys from sociological organizations that have been working for a long time. 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), 1,001 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%.

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.

During December 3-11, 2021, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion poll "Omnibus". By the method of computer-assisted telephone interviews (CATI) based on a random sample of mobile telephone numbers (with random generation of telephone numbers and subsequent statistical weighing) were interviewed 2,000 respondents living in all regions of Ukraine (except AR of Crimea). The sample is representative of the adult population (18 years and older) of Ukraine. The sample does not include territories that are temporarily not controlled by the authorities of Ukraine - the Autonomous Republic of Crimea, some districts of Donetsk and Luhansk regions.

In Luhansk and Donetsk regions, the poll was conducted only in the territory controlled by the Ukrainian authorities.

Statistical sampling error (with a probability of 0.95 and taking into account the design effect of 1.1) does not exceed: 2.4% for indicators close to 50%, 2.1% for indicators close to 25%, 1.5% - for indicators close to 10%, 1.1% - for indicators close to 5%.

KIIS conducts a survey of the population's attitude to opinion polls once a year, in December. The December 2020 poll showed that 41% of respondents trust the data of long-term working sociological organizations, 21% do not trust, others do not have a certain opinion about it. The level of trust in these sociological polls has not changed in recent years (in 2019 it was 42%, and in 2020 - 41%). The balance of trust and distrust (percentage of those who trust, minus the percentage of those who distrust) is + 20%, a year ago it was equal to + 21% (a small statistically insignificant decrease).

Якщо звинувачують соціологів, - говорила Ірина Бекешкіна, - значить, почалися вибори. На жаль, останнім часом складається враження, що вибори у нас ніколи не закінчуються. І постійною темою є продажність соціології, «замовні» дослідження і маніпуляція за допомогою даних соціологічних досліджень. Спробую в черговий раз розповісти, як працюють соціологи, і яким чином можна, а яким не можна використовувати дані соціологічних досліджень для маніпуляції суспільною свідомістю (звичайно, мова йде в основному про політичні дослідження).

KIIS inestigates the population's attitude to sociological polls once a year, each December. A poll of December 2019 found that 42% of respondents trusted sociological organizations that have been operating for a long time already, 21% percent do not trust, and others do not have a clear opinion about this. The level of confidence in opinion polls has hardly changed over the last year (in 2018 it was 43% and in 2019 - 42%). The balance of trust and mistrust (the percentage of those who trust, minus the percentage of those who do not trust) is + 21%, a year ago it equaled +23% (a small statistically insignificant decrease).
