During September 19-28, 2025, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey "Omnibus", to which, at the request of the public organization Center for Strategic Communications "Forum", a question was added regarding the perception of how the level of corruption in Ukraine had changed during the full-scale invasion. 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), 1,029 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.

From September 2 to 14, 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 related to language policy in Ukraine. 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), 2,012 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 2012 respondents (with a probability of 0.95 and taking into account the design effect of 1.3) does not exceed 2.9%. In this case, we implemented an experiment and the respondent was read one of three randomly selected language policy options (to avoid the effect of the order of responses). Each peace plan was evaluated by about 666-675 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 5.1%.

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.

Друга хвиля пілотного дослідження добробуту українців засвідчує, що відчуття сенсу в житті залишається найвищим і найстабільнішим серед інших показників, що може вказувати на його роль як психологічного ресурсу стійкості. 

Результати другої хвилі пілотного дослідження добробуту, які проводились у грудні 2024 року, засвідчують стабілізацію рівня щастя серед українців в умовах повномасштабної війни. Також зафіксовано зростання середнього рівня задоволеності життям та стабільно високі оцінки відчуття сенсу в житті. Водночас рівень  тривожності демонструє тенденцію до зростання.  

Показник особистого добробуту комплексно демонструє рівень якості життя людини. Він охоплює крім матеріального достатку задоволеність людини такими аспектами  життя як фізичне та ментальне здоров’я, професійна реалізація, освіта, безпека, особисті стосунки та соціальні зв’язки. 

Згідно з методологією Національного статистичного управління Великої Британії (ONS), за якою були проведені як перша, так і друга хвилі, вплив цих факторів кумулятивно демонструється через головних 4 показники: рівень задоволеності життям, відчуття сенсу у житті, рівень щастя та рівень тривожності. 

From September 2 to 14, 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 related to trust in the President and attitude towards holding elections. 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), 1,023 respondents were surveyed.
