Is it a lot to know 4 languages? Quadrilingual Ukrainians and Finns English, German, Swedish, Finnish English, German, Russian, Ukrainian Finland is in the European Union and NATO It is one of the best countries in the world
That very much depends on location and upbringing. There are plenty of places where there are two or more commonly used languages and so a lot of people naturally learn all of them to some extent; as you say, Ukrainians with both Ukrainian and Russian, Belgium with French, German and Dutch, Southern USA with English and Spanish etc. Colonialism also plays a major role, with a lot of places using both native languages and a European one, and more generally with English and French being the common languages or international trade and politics. Other places, where there is only one official and/or commonly used language (especially where it is English), most people will only speak that one, and people who know multiple other languages are much rarer.
My granddaughter is attending school in Belgium, and her brother is in an AB school in Switzerland. My son and daughter-in-law live in Germany. They are fluent in 5 languages and still in the equivalent of 8th grade in the U.S. Me? just English and some of the bastard dialects of Mexican and Tejano, not to be confused with formal Spanish, and a few college courses in Latin, which I haven't used in a long time.
Here in Texas German is still spoken in some regions, and Czech; we have the largest Czech newspaper outside of Czechoslovakia here as well.
