What does the Simpson Diversity Index, as used in LEED for Neighborhood Development, measure?

The Simpson Diversity Index, as applied in LEED for Neighborhood Development, measures the diversity of housing types within a neighborhood. This index is used to assess how varied the housing options are in a community, promoting a mix of housing types to accommodate different household sizes and income levels. A higher diversity of housing types contributes to a more inclusive community, which is a key goal in sustainable neighborhood development. This diversity helps in creating neighborhoods that are adaptable to various socio-economic groups and enhances community resilience.
