If you have a grant you may allocate some funds to conduct a properly designed survey accounting for different social groups, age, gender , regions. The survey will provide representable results in your research ,even if a single city such as Kyiv is selected. Otherwise, the answers in your questionnary will be skewed due to a selection bias. On this website likely you will meet people of younger generation who are also living outside of Ukraine
A simple survey should not be expensive given favourable exchange rate to Ukrainian currency.
