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.
