A Ukrainophone (Ukrainian: україномовний, ukrainomovnyi) is a person who speaks the Ukrainian language either natively or by preference. At the same time the term is used in a more specialized meaning to describe the category of people whose cultural background is associated with the Ukrainian language regardless of territorial distinctions.
There are many Ukrainophone communities in neighbouring countries with Ukraine, due to the historical spread of ethnic Ukrainian populations in areas that later became a part of those states, including Belarus, Moldova (especially Transnistria), Russia (especially Kuban, Stavropol Krai and areas of former Eastern Sloboda Ukraine), Poland, Hungary, Slovakia and Romania, as well as in continental nations and areas where Ukrainians had moved to in recent centuries or were deported to during the Soviet regime, such as Kazakhstan, the Far East, Sakhalin, Kuril Islands, Lithuania, Czech Republic, Germany, Italy, Croatia, Portugal, the U.K., etc. Additionally, there are large Ukrainophone immigrant communities in various parts of Canada, the United States (especially New York City, Baltimore) and Australia, and somewhat smaller communities in various nations of Latin America, such as Brazil, Argentina, Paraguay, and Venezuela.
Usage in Ukraine
Ukrainian vs. Russian
In the country of Ukraine almost all people are fluent in Ukrainian and it is taught to all children through the Ukrainian school system. However, many people are also fluent in Russian, due to three centuries of both voluntary and forced assimilation into the culture of first the Russian Empire and then the Soviet Union, as well as waves of ethnic Russian migrations into Ukraine during Soviet rule. This is particularly true of ethnic Russians, members of other ethnic minority groups and residents of large cities in Central, Eastern and Southern Ukraine. Ukrainophones are in the majority in most of Western and Central Ukraine, and almost in all rural areas of Ukraine, including East Ukraine. In addition, people in areas influenced by the Russian language often speak a mixed form of Ukrainian known as surzhyk, which uses a base of Ukrainian grammar but plugs in a lot of Ukrainianized Russian vocabulary into conversation.
Due to a significant lack of knowledge of Ukraine among Western journalists, which is often compounded by anti-Ukrainian propaganda coming from Russian media sources (which even led to boycotts of Russian media products in Ukraine), many of them have portrayed Russian and Ukrainian speakers as clearly defined and completely separate ethnic groups, each of which desires to exclusively dominate the Ukrainian state. The reality is that most people in Ukraine know both languages and frequently engage in language-switching as it suits them. Speaking Ukrainian or Russian in Ukraine is not regarded as a political statement, but merely a personal preference in a particular situation. For most Ukrainians, Russian and Ukrainian languages are interchangeable. Moreover, it is quite common for individuals to speak different languages to each other, as each person uses the language they are more comfortable with, without 
Usage in the Ukrainian diaspora
In Canada the term Ukrainophone is also used to differentiate Ukrainian language-speakers from ethnically Ukrainian Canadians in general. It refers to speakers of both the local Canadian Ukrainian dialect and Standard Ukrainian.
Most Ukrainian Canadians are assimilated to the North American majority and speak English. In the nomenclature of Canadian and Quebec language politics this makes them Anglophones, but some Ukrainian Canadians may also be Francophones (French-speakers). If Ukrainian is a person's mother tongue then they are considered "allophone" (neither English- nor French-speaking). Therefore, a Ukrainophone in Quebec is also an allophone.
