Housing analysts use two techniques--Components of Inventory Change (CINCH) and rental market dynamics--to look at a housing market at two points in time and explain how the observed changes came about in physical (bricks and mortar) terms. CINCH focuses first on the overall number and then the characteristics of units at different times. Using CINCH methods, analysts answer such question as: What happened to the x units that disappeared from the housing stock between the beginning and the end of the period? or Where did the increase in owner-occupied units come from? Rental market dynamics, which is really a type of CINCH analysis, focuses on the rental market with particular emphasis on the affordability of rental housing. Using rental market dynamics techniques, analysts answer such questions as: Have the number of rental units affordable to households with very low incomes increased or decreased over the period? or What happened to the units that were affordable to low-income households at the beginning of the period? Previously HUD commissioned CINCH and rental market dynamics analyses using the national American Housing Survey (AHS). This series of reports focuses on the 13 metropolitan housing markets surveyed in the 2004 American Housing Survey, comparing each with the year it was previously surveyed, either 1994 or 1995. You may also download a SAS dataset (*.exe) and an ASCII dataset (*.exe) that you can link to the regular AHS data files to produce custom tabulations of CINCH and rental market dynamics.
