Key Para from initial questions. Yet another finding against assumption of continued low headship rates.
Recent independent advice on the assessment of housing needs is contained in the Planning Advisory Service paper ‘Ten key principles for owning your housing number – finding your objectively assessed need’. This in turn refers to the interactive web tool ‘What homes where’ which provides a ready source for any local planning authority to derive household projections for its area and compare trends with nearby areas. ‘What homes where’ advises that caution should be adopted in using alternative assumptions from those in the toolkit and strongly advises reading the Cambridge Centre for Housing and Planning Research report CCHPR report ‘Choice of Assumptions in Forecasting Housing Requirements’ before doing so. In particular the web tool advises applying caution if the trends experienced in the past 5 years reflect a period of particular economic decline or buoyancy. It indicates that projecting forward recessionary trends may lead to concealed households not being catered for and a consequent underestimate of the true level of household change. Town and Country Planning ‘Tomorrow Series Paper 16 (‘New estimates of housing demand and need in England, 2011 to 2031’) by Alan Holmans also assesses the possible implications of underestimating need on the basis of the 2011 census.
