HFGⓘ
Household Formation Gap (HFG) is a secondary market indicator that measures hidden housing demand created by shrinking household sizes. As average household size decreases — due to divorce, single living, empty nesting, delayed marriage — more housing units are needed even without population growth. HFG compares the estimated number of households needed today versus 15 years ago: (population ÷ avg household size). This is a demographic trend signal, not a primary market indicator like income-based affordability or comparative market analysis.
