How the Other Half Lives

In How the Other Half Lives, New Yorkers read with horror that three-quarters of the residents of their city were housed in tenements and that in those tenements rents were substantially higher than in better sections of the city. In his book Riis gave a full and detailed picture of what life in those slums was like, how the slums were created, how and why they remained as they were, who was forced to live there, and offered suggestions for easing the lot of the poor.
