Press release prepared by KIIS President Volodymyr Paniotto

From May 7 to June 3, 2026, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey, to which, on its own initiative, added a question about self-assessment of happiness. 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), 2007 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 2,000 respondents (with a probability of 0.95 and taking into account the design effect of 1.3) does not exceed 2.8%.

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.

70% of Ukrainians would vote in favour of EU membership if a referendum were held.

This is according to the analytical report “Opinions and Views of the Population of Ukraine on European Integration”, prepared by the Kyiv International Institute of Sociology (KIIS) at the request of the Ukraine2EU programme and in cooperation with the Office of the Deputy Prime Minister for European and Euro-Atlantic Integration of Ukraine. The survey was conducted in May-June 2026.

Support has remained stable within the 68-72% range since 2022. At the same time, 30% of Ukrainians are strong supporters of accession, while another 32% are moderate supporters (those who say they support accession “rather strongly”).

Among the expected benefits, respondents cite wage growth, freedom of movement, and alignment of legislation with EU standards. Key concerns include price increases, outflow of skilled workers, and additional costs for businesses.

Press release prepared by Volodymyr Paniotto and Anton Grushetskyi

The absolute majority of Ukrainians (at least 90%) support the Independence of Ukraine. Only 1% believe that Ukraine should unite with Russia. Absolute support for Independence was a fait accompli before 2014, but now this support has become even higher.

Attitudes towards Ukraine’s Independence Day have changed radically from 2013 to 2026. In 2013, this holiday was the most important or favorite for 12% of Ukrainians, and in 2026, it was for 54%. In 2013, it was one of the least popular holidays (only Constitution Day was less popular), and now it is one of the most popular holidays in Ukraine, second only to the two main religious holidays.

From June 17 to 23, 2026, the Kyiv International Institute of Sociology (KIIS) conducted its own all-Ukrainian public opinion survey, to which, on its own initiative, added a question about the attitude towards the figure of Stalin. 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), 1,005 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.

 We also note that the calculations in the press release are rounded to integer values. In some cases, the % sum may not add up to exactly 100% due to rounding.

Attitude towards the figure of Stalin is one of the indicators characterizing the level of decommunization in society. KIIS from time to time asks question about attitude towards Stalin in various formulations. In June 2026, we repeated two questions that were asked in previous studies, which makes it possible to trace the dynamics of Ukrainians' attitudes towards Stalin.

During July 16-31, 2026, the Kyiv International Institute of Sociology (KIIS) conducted an all-Ukrainian public opinion survey. The survey was conducted using a mixed-mode method: half of the respondents were interviewed using computer-assisted telephone interviews (CATI), and half were interviewed using face-to-face interviews using tablets.

Telephone interviews were conducted using a database of randomly generated mobile numbers. Interviewers then called the mobile numbers and invited citizens to participate in the survey (if they were living in the territory controlled by Ukraine at the time of the interview and were 18 years old). No additional quotas were applied, and the final array was statistically weighted.

Personal interviews were conducted on the basis of a stratified three-stage random sample with quota selection at the last stage. The sample was developed only for the territories controlled by the Government of Ukraine. Initially, the sample was stratified by oblast and urban/rural area (the division into urban/rural area was carried out on the basis of the averaged share of citizens who reported living in a village based on the results of telephone surveys by KIIS in 2026 (based on a random sample). Then, at the first stage, polling stations were randomly selected within the stratum (a total of 90 polling stations in 54 different settlements were selected). In the second stage, the starting address was selected within the station, and in the third stage, citizens were selected according to the gender-age task. The final array was also weighted to be fully equivalent in these dimensions to the array of telephone interviews.

In both surveys, the planned sample size was 900 respondents, of which 300 were from Kyiv city. For the analysis, the “weight” of Kyiv city was adjusted to the statistics during the statistical weighting of each of the arrays.

In total, 1,808 interviews were conducted within the framework of the research, of which 905 were telephone interviews (including 305 with those currently living in Kyiv city), 903 were personal interviews (including 302 with those currently living in Kyiv city).

Formally, for normal circumstances, the statistical error of the sample (with a probability of 0.95 and a design effect of 1.3 and taking into account the sample structure with additional interviews in Kyiv city) does not exceed 3.5% for a sample of 1,808 respondents (full sample) and 4.9% for a sample of about 900 respondents (separate telephone interviews and individual personal interviews).

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.

In the appendix you can find the results separately for telephone interviews and for personal interviews.

We also note that the calculations in the press release are rounded to integer values. In some cases, the sum of % may not add up to exactly 100% due to rounding (the same applies to the calculation of the balance of trust-distrust).
