This work records extensive interviews and observations of urban street-dwellers, presenting detailed accounts of their trades, earnings, domestic conditions, and daily struggles. It categorizes various street occupations—men, women, and children—offers quantitative information on markets and sales, and includes illustrations and market statistics. Combining first-person testimony with investigative reporting, it aims to portray labor, poverty, and survival strategies in the metropolis, highlighting patterns of income, family life, seasonal variation, and social marginality without sensationalism.
