 The population surge of the 1950s energized Chicago's Ukrainian Village, and spurred construction of new parishes and the founding of new civic and cultural organizations.The fourth, and most recent, wave of immigration from Ukraine to the United States occurred in the 1990s, following the dissolution of the Soviet Union and subsequent opening of Ukraine's borders to the west.While the largest influx of Ukrainians to Chicago occurred shortly after 1990, immigration to Chicago from Ukraine continues to the present time.
