Economic factors are undeniably a significant driver of residential zonation. The availability of affordable housing is a key determinant, with lower-income households often concentrated in areas with cheaper property prices, potentially further from city centres and with poorer amenities. Income levels directly correlate with housing choices; higher earners tend to favour areas with better schools, transport links, and amenities, leading to affluent residential zones. Employment opportunities also play a role, with people often choosing to live close to their workplaces.
However, the statement that economic factors are the *primary* driver is debatable. Social and cultural factors significantly influence residential choices. People may prefer to live in areas with communities that share their cultural background or values. Ethnic segregation, often linked to economic disparities, is a clear example of this. Historical factors, such as the legacy of industrial development and the subsequent decline of certain industries, have also shaped residential patterns, leaving behind areas with social and economic challenges. Planning policies, intentionally or unintentionally, can also reinforce or counteract economic trends, influencing the types of housing that are built and where.
In conclusion, while economic factors are a powerful force, residential zonation is a complex interplay of economic, social, cultural, historical, and planning influences. It's an oversimplification to attribute it solely to economics.
