The Progressive Movement's strongest supporters were in urban parts of the United States, while the Populists were strongest in rural areas. The Progressive Movement aimed to address social and political issues in urban areas, such as corruption, poverty, and inequality. They advocated for reforms in areas like labor rights, women's suffrage, and public health. On the other hand, the Populists primarily represented the interests of farmers and rural communities, focusing on economic issues such as agricultural policies, currency reform, and the regulation of big business. This divide between urban and rural support reflects the different priorities and concerns of these two movements.
