Migration from Poland to the US 1820-1957

Between 1820 and 1957, at least 400,000 people migrated from Poland to the United States. Due to Poland's complicated border-history, many Polish migrants were recorded as having other nationalities, particularly Austrian, German and Russian (all migrants who claimed to be Polish between 1899 and 1919 were recorded as being one of these other nationalities), therefore the exact number of Polish migrants to the United States during this time is unknown. From 1920 onwards, Poland's sovereignty and independence was acknowledged by the United States government (US President Wilson was instrumental in helping to establish the independent Republic of Poland), and the figures become more reliable. The years with the highest number of documented Polish migrants to the US was after the First World War in the early 1920s, with almost 100,000 Poles migrating in 1921 alone, although the number fell below 10,000 again by 1925.

自1820年至1957年间，至少有40万人从波兰移民至美国。鉴于波兰错综复杂的边界历史，许多波兰移民被记录为其他国籍，尤其是奥地利、德国和俄罗斯（1899年至1919年间声称自己是波兰的移民均被记录为上述其他国籍之一），因此，此期间移民至美国的波兰移民确切人数不得而知。自1920年起，美国政府对波兰的主权和独立予以认可（美国总统威尔逊在协助建立独立的波兰共和国方面发挥了关键作用），数据因而变得更加可靠。一战后，20世纪20年代初是记录在案的波兰移民至美国的数量最高的时期，仅1921年就有近10万名波兰人移民，尽管到1925年，这一数字又降至1万人以下。
