A comprehensive poll released on 8 May by the Pew Research Centre surveyed opinions in Ukraine and Crimea on the subject of the unrest. The poll was taken after the annexation of Crimea, but prior to the clashes in Odessa on 2 May. 93% of westerners and 70% of easterners polled said that they wanted Ukraine to remain united. Despite international criticism of 16 March referendum on Crimean status, 91% of those Crimeans polled thought that the vote was free and fair, and 88% said that the Ukrainian government should recognize the results.
