Birth and death rates directly influence housing demand and supply dynamics. High birth rates typically increase the need for housing as families expand, leading to greater demand for new homes, while lower death rates can result in population growth, further straining existing housing resources. Conversely, declining birth rates and higher death rates can lead to a surplus of housing, potentially resulting in vacant properties and decreased property values. Therefore, understanding these demographic trends is essential for effective housing policy and urban planning.
