 Many of them were recorded as Russian or Polish, depending on the region of Belarus where they were born.The largest concentrations of Belarusian Americans are in the metropolitan New York area, New Jersey (especially Highland Park and South River), Cleveland (and its suburbs), Chicago (recent immigrants concentrated around Wheeling), Los Angeles, and Detroit.There were several waves of Belarusian influx into the USA, one before the Russian Revolution, then in 1919-1939 from West Belarus, then in the late 1940s-early 1950s (after the Second World War), and after the collapse of the USSR in the 1990s.
