Ellis Island
Between 1905 and 1914, an average of one million immigrants per year arrived in the United States. Immigration officials reviewed about 5,000 immigrants per day during peak times at Ellis Island. Two-thirds of those individuals emigrated from eastern, southern and central Europe. The peak year for immigration at Ellis Island was 1907, with 1,004,756 immigrants processed. The all-time daily high occurred on April 17, 1907, when 11,747 immigrants arrived. After the Immigration Act of 1924 was passed, which greatly restricted immigration and allowed processing at overseas embassies, the only immigrants to pass through the station were those who had problems with their immigration paperwork, displaced persons, and war refugees. Today, over 100 million Americans—about one-third to 40% of the population of the United States—can trace their ancestry to immigrants who arrived in America at Ellis Island before dispersing to points all over the country.
New York (state)
When the federal government assumed control, it established the Bureau of Immigration, which chose the three-acre Ellis Island in Upper New York Harbor for an entry depot. Already federally controlled, the island had served as an ammunition depot. It was chosen due its relative isolation with proximity to New York City and the rail lines of Jersey City, New Jersey, via a short ferry ride. While the island was being developed and expanded via land reclamation, the federal government operated a temporary depot at the Barge Office at the Battery.
