Housing Inventory System (HIS)
Part of the annual work program at the Center for Demographic Research is to produce population and housing estimates for sub-city areas in Orange County. These estimates are used to monitor and calibrate the Orange County Projections that are used for a host of planning and policy applications including the Regional Transportation Plan, Regional Housing Needs Assessment (RHNA), OCTA's transportation modeling and the Congestion Management Plans to name a few. The foundation for developing these estimates is based on data (housing stock changes) provided by each jurisdiction.
CDR requests that each jurisdiction provide a report of their annual dwelling unit gains and losses by structure type with address information for each calendar year. CDR has designed a standardized form to use to create a monthly or yearly summary of the data we are requesting.
