General Register Office for S C O T L A N D information about Scotland's people Background Housing Need & Demand Assessment Guidance (HNDA) 2008 refers to GROS household projections and small area statistics. I’ll cover: –What statistics we produce which may be of use –Results –How to access and interpret our statistics

General Register Office for S C O T L A N D information about Scotland's people Purpose of GROS household projections Mainly used to inform local authority decisions about future housing and service need –Need to know projected number of households, and type. GROS produces projections in a consistent way across the country. Some areas produce their own local projections. These can be used where this can be justified.

General Register Office for S C O T L A N D information about Scotland's people How they are produced Produced every 2 years, to cover a 25-year period. Based on population projections; Subtract communal establishment population; Project household composition information from the Censuses.

General Register Office for S C O T L A N D information about Scotland's people Projected percentage change in households, Wide geographic variation

General Register Office for S C O T L A N D information about Scotland's people High migration variants We have also produced LA projections which incorporate higher projected migration. Areas with highest in-migration are most affected, e.g., Aberdeen and Edinburgh. Migrants tend to be younger, so the biggest impact on household structure is in households with children (assuming the migrants stay and have families here).

General Register Office for S C O T L A N D information about Scotland's people Projections for different areas GROS produces projections for Councils, National Parks and Strategic Development Plan Areas. Software such as Popgroup/Housegroup exists, which some councils use to produce their own projections for small areas, or using different assumptions. We are working to support councils in using this. Note: projections for smaller areas will be less reliable.

General Register Office for S C O T L A N D information about Scotland's people Interpreting household projections GROS projections are based on past trends. They don’t take account of: –Future policy initiatives –Economic predictions –Planned housing developments –Potential discrepancies between housing supply and demand

General Register Office for S C O T L A N D information about Scotland's people Scottish Neighbourhood Statistics We also publish small area statistics on housing and households on –Number of dwellings –Council Tax band –Type of dwelling –Number of rooms per dwelling –Density of housing –% occupied –% vacant –% second homes Data comes from Council Tax information. Published annually, along with summary LA publication.

General Register Office for S C O T L A N D information about Scotland's people Net vs. gross household formation HNDA asks ‘How many newly arising households are likely to be in housing needs each year?’. Need figures on newly-formed households, which GROS projections don’t provide. 1.Glen Bramley’s affordable housing needs study contains figures for each LA – shows an average of 2.4% of households are newly-formed. 2.We are working on another method based on DCLG guidance. Initial results suggest that the figures are similar.
