From December 4 to 10, 2023, the Kyiv International Institute of Sociology (KIIS) conducted an all-Ukrainian public opinion survey "Omnibus", which included questions about the direction of affairs in the country and trust in certain political figures. Bythemethodofcomputer-assistedtelephoneinterviews(CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting), 1,200 respondents living in all regions of Ukraine (except the Autonomous Republic of Crimea) were interviewed. The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived on the territory of Ukraine (within the boundaries controlled by the Ukrainian authorities until February 24, 2022). The sample did not include residents of territories that were not temporarily controlled by the authorities of Ukraine until February 24, 2022 (AR of Crimea, the city of Sevastopol, certain districts of the Donetsk and Luhansk oblasts), and the survey was not conducted with citizens abroad.

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 1.1) did not exceed 3.2% for indicators close to 50%, 2.7% for indicators close to 25%, 2.1% - for indicators close to 10%, 1.4% - for indicators close to 5%.

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

In general, we believe that the obtained results are still highly representative for the population of Ukraine living in the territory under the control of the Government, and allow a fairly reliable analysis of the public moods of the population.

From May 26 to June 5, 2023, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey "Omnibus". Bythemethodofcomputer-assistedtelephoneinterviews(CATI) based on a random sample of mobile phone numbers (with random generation of phone numbers and subsequent statistical weighting), 984 respondents living in all regions of Ukraine (except the Autonomous Republic of Crimea) were interviewed. The survey was conducted with adult (aged 18 and older) citizens of Ukraine who, at the time of the survey, lived on the territory of Ukraine (within the boundaries controlled by the authorities of Ukraine until February 24, 2022). The sample did not include residents of territories that were not temporarily controlled by the authorities of Ukraine until February 24, 2022 (AR of Crimea, the city of Sevastopol, certain districts of the Donetsk and Luhansk oblasts), and the survey was not conducted with citizens who left the country 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 1.1) did not exceed 3.4% for indicators close to 50%, 3.0% for indicators close to 25%, 2.1% - for indicators close to 10%, 1.5% - for indicators close to 5%.

Under conditions of war, in addition to the specified formal error, a certain systematic deviation is added. In particular, if in May 2022, among all the respondents we interviewed, 2.5-4% lived in the territories occupied after February 24 (and this corresponded to the percentage of those who live there, because the generation of telephone numbers was random), now due to the occupiers turning off the telephone connection, not a single respondent who currently lives in occupied settlements was included in the sample (along with this, out of a total of 984 respondents, 32 respondents lived in a settlement that is currently occupied until February 24, 2022). It is important to note that although the views of the respondents who lived in the occupation were somewhat different, the general trends were quite similar. That is, the impossibility of interviewing such respondents does not significantly affect the quality of the results. There are other factors that can affect the quality of results in "wartime" conditions (see Annex 2).

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

During February 5-13, 2022, 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 phone numbers (with random generation of phone 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%.

During January 20-21, 2022, the Kyiv International Institute of Sociology (KIIS) conducted an all-Ukrainian public opinion poll. 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 1205 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.

The statistical error of the sample (with a probability of 0.95 and taking into account the design effect of 1.1) does not exceed: 3.2% for indicators close to 50%, 2.7% for indicators close to 25%, 2.1% - for indicators close to 12%, 1.4% - for indicators close to 5%.
