· Explicitly dealing on housing affordability and measurement methods.

· HAI—fails to accurately reveal housing affordability problems of households with very low-income, as they merely integrate average figures.

· Article is selected if it discussed a validation of existing method or utilized or proposed or developed a method of housing affordability analysis
