New York in the 1900s
A newly consolidated metropolis of immigrants, tenements, garment shops, Tammany politics, and a subway opening under City Hall.

Looking around
You stand by City Hall Park9, in the city that has only lately become five boroughs under one municipal government5. Around this lower Manhattan point is the largest American city, with 3,437,202 people in 19001 and still more by the decade’s end. The streets above are crowded enough that reformers argue over tenements, fire escapes, air, and windows3. Underfoot, work has changed the city: the first subway begins here, and by 1904 trains run from City Hall to 145th Street9. South and west, the harbor brings newcomers toward Ellis Island4, where more than a million people pass in 1907. North of here and across Manhattan, hundreds of textile factories6 employ immigrant garment workers. The city’s calendar and arguments are public ones: Times Square celebrations5, shirtwaist strikes8, and the daily authority of a mayor, borough presidents, comptroller, and Board of Estimate.
Work
Needles and long hours
A large share of industrial work visible from lower Manhattan belongs to clothing: more than 450 Manhattan textile factories6 employ about 40,000 garment workers6. In the shirtwaist trade, weeks of 65 to 75 hours8 are reported.
Who lived here
An immigrant metropolis
New York is already enormous, with 3,437,202 people in 19001. At Ellis Island, the decade peaks in 1907 when more than one million people pass through4 the immigration station.
Home & table
Tenement reform world
Housing is a political and bodily question: laws require fire escapes and a window for every room3 facing light and air. The census counts 249,991 dwelling places2 for more than three million city residents.
Money
Pay by skill and place
In the shirtwaist shops, learners often earn $3 or $4 a day8, while semi-skilled operators may make $7 to $128. The difference marks gender, training, bargaining power, and the subcontracting system.
Law & power
A new municipal machine
The city has recently become five boroughs under one municipal government5. By 1901 its charter gives formal power to a mayor, borough presidents, a comptroller, a City Council president, and a Board of Estimate7.
In the air
Labor, suffrage, reform
The great public argument of 1909 is work itself: the Uprising of the 20,0008 brings young immigrant women into the street. Shirtwaist workers are also linked to Yiddish-speaking Jewish and Italian immigrant communities8 and to women’s suffrage agitation.
What people feared
Fire, illness, overcrowding
Tenement law speaks to everyday danger through fire escapes, air, and windows3. Ellis Island records show another fear: from July 1905 to June 1906, 1,990 immigrants were admitted to New York City hospitals4.
Roads & news
Subway and spectacle
News arrives through newspapers, crowds, and public ceremony: the subway opens from City Hall9 in 1904. The city also invents a new annual spectacle when the illuminated Times Square ball5 first drops for 1908.
