Final answer:
Residential instability and substandard housing can result in a lack of stability, negative health effects, and a perpetuation of poverty and social inequality.
Step-by-step explanation:
Residential instability and substandard housing have several key impacts on individuals and communities. Firstly, it can lead to a lack of stability in a person's life, as they may have to frequently move from one place to another. This can disrupt their educational opportunities, social connections, and access to essential services. Secondly, substandard housing can have negative effects on physical and mental health. For example, inadequate ventilation and exposure to environmental hazards can lead to respiratory problems and other health issues. Lastly, residential instability and substandard housing can contribute to a cycle of poverty and social inequality, as individuals and families may struggle to escape poverty due to limited resources and opportunities.
