On this basis most of Shetland's communities are likely to experience population decline up to the year 2011 with the exception of some communities within easy commuting distance of Lerwick. Retaining population in a community is seen as essential in order to underpin the viability of local services including schools and shops. This increase was due to a reduction in Shetland's average household size from 3.0 to 2.6 persons per household, a trend which is expected to continue. By making assumptions about the size of future households it is possible to project the number of future households. 13.4 One factor which can distort projected housing need calculations is the extent of commuting.
Available information suggests that commuting is significant and increasing.
From at least the early 1970s concern has been expressed about the growth of commuting and its possible impact on settlement patterns and the viability of rural communities. The continuing concentration of population, jobs and services around Lerwick is a cause for concern, the strategy proposed will seek to address this imbalance by encouraging development to support existing settlements throughout Shetland and the communities they support. The Council must develop a co-ordinating role to provide an integrated housing service, ensuring that the different partners and agencies involved in housing are aware of housing needs, the role they can play in meeting those needs and the support and guidance the Council can give. The condition of the housing stock is generally good. The Council recognises the need to maintain and improve Shetland's housing stock, within both the private and public housing sectors.
