Final answer:
Intersectional discrimination refers to negative impacts created by linked practices across different institutional areas, amplifying barriers for marginalized groups.
Step-by-step explanation:
The type of institutional discrimination that refers to practices in one institutional area having a negative impact because they are linked to practices in another institutional area is known as intersectional discrimination. This form of discrimination can occur when interconnected social categorizations such as race, class, and gender create overlapping systems of disadvantage. An example is when institutional racism within the housing sector impacts the educational opportunities available to a child due to segregated neighborhoods leading to inequitable school funding, which can be sourced from property taxes in different districts. These systemic links between different institutional areas create barriers that can amplify the adverse impacts on marginalized groups.
