Comprehensive Housing Market Analysis (CHMA) reports are the most in-depth reports on market conditions. Each report focuses on a particular market area and analyzes conditions and key economic, demographic, and housing variables during three main periods: between the two most recent Decennial Census years, from the most recent Decennial Census year to the current date of the study, and from the current date of the study to a 3-year forecast date. The reports are useful to HUD in its operations as well as builders, mortgagees, and others concerned with local housing conditions and trends. One of the key components of the CHMA report is the inclusion of an estimate of the demand for sales and rental housing during the three year forecast period that would need to be met in order to achieve balanced housing market conditions. CHMA reports are not released on a fixed schedule but the Department tries to publish 40-60 new reports each year.
