Final answer:
An economy emphasizing secondary economic activities leads to a rural-to-urban population shift where individuals move to urban centers in search of industrial and manufacturing jobs, resulting in increased urban growth and changes in family dynamics and income levels.
Step-by-step explanation:
An economy focused on secondary economic activities is characterized by industrialization and the manufacturing of products from raw materials. These activities often lead to macroeconomic changes, including a specific pattern of population distribution. As individuals move from rural areas to urban centers in search of employment opportunities in manufacturing and related industries, the result is a rural-to-urban shift. This migration is reflective of societal progression through development stages, where the concentration of the workforce transitions from primary activities in agricultural settings to industrial and urban living. Various countries experience these changes as they develop, with more people working in factories and construction rather than in fields and primary extraction industries.
In societies where secondary economic activities dominate, the urban areas often swell as they become hubs of industrial activity, drawing people from rural areas. This migration leads to an increased urban population and often the rise of self-constructed housing areas, sometimes known as slums, due to the rapid influx of new residents. Over time, income levels typically increase along with the urban population, and family sizes tend to decrease due to the urban lifestyle and its associated costs and family planning practices. This urban population growth is often targeted by multinational corporations for its labor supply, which fuels the expansion of secondary industries and the urban infrastructure to support them.
