The Components of Inventory Change (CINCH) report measures changes in the characteristics of the housing stock of the United States. Using data collected from the national American Housing Survey (AHS), conducted every two years, the characteristics of individual housing units are compared across time. This comparison allows researchers to see not only changes in the characteristics of housing units, but also in the characteristics of occupants. Information is available on the characteristics of units added and removed from the housing stock.
First-time users of this publication are advised to refer to the Appendices and notes immediately preceding the tables for explanations of the columns and how to interpret the results. The Appendices also contain the definitions of all of the characteristics, cautions, and explanations about some of the results.
Each report has two sections. The first section, labeled "Losses," shows the losses to the housing stock in the two-year period using the first year as the base year. In other words, the first section shows the disposition of all the units that were present at the beginning of the period. The second section, labeled "Gains," shows the gains in the housing stock during the two-year period, using the second year of the period as the base year. That is to say, the second section shows the source of all the units that were present at the end of the period.
The "Summary of Components of Inventory Change: 1985-1995" document is a compilation of the five two-year reports
All of the reports are based on the American Housing Survey
national sample. The results presented here are not directly
comparable to the Census Bureau publications "Components
of Inventory Change: 1980-1991," or "Components
of Inventory Change: 1980-1993."
2017-2019 CINCH and Rental Dynamics
The 2017-2019 National and Metropolitan CINCH and Rental Dynamics reports are temporarily unavailable due to a coding error that did not account for a change to the classification of noninterview cases during the time period. Specifically, a change to the classification of cases recorded as "demolitions and disaster losses" affected how temporary and permanent losses were tabulated in the reports and how weights for the analysis were calculated. HUD has removed the reports until the full scope of the impact of this change is known. We apologize for any inconvenience this creates and are working to provide corrected 2017-2019 National and Metropolitan CINCH and Rental Dynamics reports as soon as possible.

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.
