Final answer:
The percentage of the population living in cities with 100,000 people or more grew substantially between 1860 and 1910. The top job sectors during the industrialization period included factory work and manufacturing. Today, key industries include technology, healthcare, renewable energy, financial services, and e-commerce.
Step-by-step explanation:
The percentage of the population living in incorporated places (towns and cities) with a population of at least 100,000 increased significantly between 1860 and 1910. In 1860, only a small fraction of Americans lived in large cities, but by 1900, around 30% lived in cities, reflecting a major demographic shift. As such, the percentage living in these large urban spaces in 1910 was likely much higher than in 1860.
The increase in the percentage of the population that lived in incorporated areas of at least 2,500 people between 1860 and 1910 was dramatic. In 1880, half of all Americans lived and worked on farms, and by the early 1910s, this number had significantly declined, with an increasing number living in urban and suburban areas.
During this industrial period, jobs in factories, manufacturing, and urban development had substantial growth. Advances in technology decreased the need for labor on farms and increased demand for industrial labor in cities.
Since 1910, there has been a continued trend towards urbanization. The balance of people living in small and large cities has continued to shift towards larger urban centers, as evidenced by the increasing percentage of the population living in urban areas over time, exceeding 80% in the United States as of the early 21st century.
For a list of the top 5 industries today, considering technological advancements and the evolution of the global economy, industries likely to be included are technology, healthcare, renewable energy, financial services, and e-commerce.
