Russia's full-scale invasion of Ukraine, which began in 2022, has led to tens of thousands of deaths, millions displaced, and extensive destruction of the country's infrastructure and economy.

In response to the invasion, public opinion in Ukraine has shifted dramatically, fostering a stronger national identity and an increased readiness to resist foreign aggression.

By 2024, approximately 80% of Ukrainians identify primarily as 'citizens of Ukraine,' reflecting heightened social cohesion and a sense of national identity.

Public involvement in mutual aid has surged, with over 90% of Ukrainians participating in defense efforts, primarily through financial contributions and volunteer work.

Trust in the military has soared from 72% to 96% during the first year of the war, while confidence in President Volodymyr Zelensky has risen from 27% to 84%.

Despite worsening living conditions, approval for the government has increased significantly, climbing from just 5% in November 2021 to 41% by December 2022.

Amidst the war's toll, optimism about Ukraine's future persists, with only 19% believing the economy will be destroyed in the next decade, and a majority envisioning a prosperous Ukraine within the EU.

Since the onset of the war, regional and ethnic divisions in Ukraine have diminished, with support for EU accession rising across all regions.

By July 2022, support for EU membership among Ukrainians reached 81%, while 71% favored NATO membership, coinciding with a dramatic decline in positive views of Russia to just 2%.

The annexation of Crimea in 2014 marked a pivotal moment, leading to increased support for NATO membership, which has continued to grow since the 2022 invasion.

As of October 2022, 60% of Ukrainians felt part of the national resistance, and 84% reported an increased use of the Ukrainian language.

The Kyiv International Institute of Sociology (KIIS) has been conducting national surveys since Ukraine's independence in 1991, maintaining its research focus on areas under Ukrainian control even during the war.
