A joint survey by American government agency Broadcasting Board of Governors and polling firm Gallup was taken during April 2014.[260] It polled 500 residents of Crimea. The survey found that 82.8% of those polled believed that the results of the Crimean status referendum reflected the views of most Crimeans, whereas 6.7% said that it did not. 73.9% of those polled said that they thought that the annexation would have a positive impact on their lives, whereas 5.5% said that it would not. 13.6% said that they did not know.[260]
A comprehensive poll released on 8 May 2014 by the Pew Research Centre surveyed Crimean opinions on the annexation.[261] 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 recognise the results.[261]
