 Massive unemployment of factory workers ensued, in turn prompting both urban and rural Poles to emigrate.In the Second Polish Republic (1918–1939), unemployment was among the worst problems of the economy, particularly during the Great Depression (1929–1934).The number of registered unemployed jumped from 185,000 in 1928 to 466,000 in 1936; in 1932, there were 240,000 unemployed industrial workers, or one-third of the total in that field.
