Components of Inventory Change (CINCH) Reports

Published by U.S. Department of Housing and Urban Development | Department of Housing and Urban Development | Metadata Last Checked: February 19, 2026 | Last Modified: 2020-10-01
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. he CINCH is produced after each AHS is collected (the AHS is collected every two years in odd-numbered years)
