In 1939 the town had 736 inhabitants. Nida became nearly uninhabited, like all of the Curonian Spit, as a result of the Red Army advance and the Evacuation of East Prussia at the end of World War II, and the eventual expulsion of surviving German inhabitants. The town was reassigned to Lithuania under border changes promulgated at the Potsdam Conference, and became part of the Lithuanian SSR within the Soviet Union; since 1990 it has been part of independent Lithuania.
