У період з 11-16 лютого 2021 р. було проведено спільне дослідження силами двох дослідницьких центрів, КМІС та СОЦИС.

Загалом було опитано 3000 респондентів - по 1500 кожним з центрів.

Метод збору первинної соціологічної інформації — телефонне інтерв’ю CATI (computer-assisted telephone interviews);

Дослідження проводилось по всій території України (в усіх областях та в т.ч. м.Київ), окрім окупованих територій АР Крим, частини Донецької та Луганскої областей; 

Результати репрезентативні на рівні всієї країни за показниками віку (старші за 18 років), статі, типу поселення (місто/село) та поділу країни на регіони;

Among these candidates V. Zelenskyi would receive relatively the most votes, with 16.2% of all respondents and 22.7% of those who decided on the choice. In second place would be P. Poroshenko - 13.1% among all respondents and 18.3% among those who decided. In third place - Yuliia Tymoshenko, with indicators of 10.3% and 14.5%, respectively.

As of February 5-7, three parties have support at once, which differs within the statistical error, in fact, these three parties "share" the first - third places. In addition, the fourth party lags minimally behind the formal leaders (and its support is lower in terms of error compared to the party that formally ranks third in the ranking). Thus, the "YeS" party would get relatively the most votes, for which 12.2% of all respondents and 18.1% of those who decided on the choice would vote; "OPZZh" party - 11.4% and 16.8%, respectively; the "Sluha Narodu" party - 10.5% and 15.5%; "Batkivshchyna" party - 8.9% and 13.2%. Next are "Syla i Chest" (respectively 4.3% and 6.3%) and the Radical Party (3.5% and 5.2%). "Sharii’s Party" (2.6% and 3.9%), "Holos" (2.5% and 3.7%) and "Hroisman's Ukrainian Strategy" are slightly below the barrier to entry. (2.1% and 3.2%).

Given the sensitivity of the issues related to the various "bans", the KIIS has formulated two question options. For correctness, the "split-sample" procedure was used, according to which half of the randomly selected respondents were asked one wording of the question, the other half - the second wording. An experiment with a difference in the wording of the questions showed that those who support the decision of the National Security and Defense Council (it is mostly the population of the West and the Center) and those who do not support (it is the majority of the population of the South and the East), are approximately equally

In general, 34.6% of respondents in this formulation consider the ban a necessary step, while 40.8%, on the contrary, consider it a mistake. If in the West and in the Center support of a step rather prevails, in the South, the East and Donbas there are more of those who consider such step as a mistake.
