Final answer:
The increase in urbanization and industrialization in the late 1800s led to the need for urban social programs due to poor living and working conditions, as well as the integration of a large influx of immigrants.
Step-by-step explanation:
The greatest need for urban social programs during the late 1800s was created by rapid urbanization and industrialization. This era saw a massive influx of both rural Americans and immigrants into urban areas, driven by technological advancements like electricity and steam power, which fueled factory growth and made industrial labor abundant. Consequently, urban centers struggled to accommodate the surging population, which resulted in poor living and working conditions. This necessitated reforms, including improved public health, housing regulations, and education, to address the challenges facing the working class in urban settings.
In addition to technological innovations, which brought about the need for workers to move closer to industrial jobs, a myriad of social issues contributed to the need for social programs. These issues included inadequate housing, lack of sanitation, and the need for public education to prepare a workforce suitable for an industrialized society. Also, the influx of immigrants who required assistance to integrate and find employment in their new environment added to the demand for urban social services.
As cities continued to expand, the implementation of public health measures, the regulation of housing conditions, and the creation of government jobs based on qualifications exemplified the measures taken to improve living conditions and societal structure. Institutions like settlement houses, led by reformers such as Jane Addams, became crucial in providing community support, education, and daycare—laying the groundwork for the future of urban social engagement.
