4.1 Household estimates from Council Tax systems
Each local authority keeps a record of all dwellings and any discounts or exemptions they are entitled to, for Council Tax billing purposes. If a dwelling is vacant, or is a second home, it is entitled to a Council Tax discount or exemption. This makes it possible to estimate the number of dwellings which are occupied or vacant. An occupied dwelling is approximately equivalent to a household.
Council Tax systems also hold records of other discounts or exemptions which provide information on household type. Dwellings with just one adult, or one adult living with children or with adults who are ‘disregarded’ for Council Tax purposes, are entitled to a 25 per cent Council Tax discount. Certain types of dwellings are occupied but exempt from paying Council Tax, such as all-student households and dwellings which are owned by the Secretary of State for Defence for providing armed forces accommodation. Summary statistics on these household types are also included in this publication.
Dwellings and households (Tables 1 and 2)
Summary information on the number of dwellings entitled to different discounts or exemptions is provided by each local authority to the Scottish Government, using the form ‘Ctaxbase’ ( http://www.scotland.gov.uk/Topics/Statistics/Browse/Local-Government-Finance/DataSupplierArea). The information on the number of dwellings contained in Table 2 is based on these figures.
In order to produce the household estimates shown in Table 1, the figures in Table 2 are first adjusted from September back to June, as the mid-year population estimates and household projections are both based on June. A number of factors can lead to differences between the number of households recorded in Council Tax systems and in the 2001 Census. This can include the treatment of vacant dwellings, shared dwellings, holiday lets, caravans, and some communal establishments. In order to improve consistency and comparability, the household estimates for each local authority area are adjusted by the difference between the number of households recorded in the 2001 Census and the 2001 Council Tax figures. The same adjustment is applied to each year's figures, and will affect the number of households, but not the trends over time.
A more detailed description of the method and sources used can be found in the publication ‘Household estimates for Scotland by local authority 1991-2004’, available from the GROS website at http://www.nrscotland.gov.uk/statistics-and-data/statistics/statistics-by-theme/housholds/household-estimates.
Vacant dwellings and second homes (Tables 7 to 10)
Clackmannanshire and Renfrewshire cannot separately identify vacant dwellings and second homes. Three per cent of dwellings in these areas are in this category. In the 2001 Census, less than 0.2 per cent of dwellings in these areas were classed as second homes, so the total figures have been included under 'vacant dwellings'.
Neighbourhood statistics
The Ctaxbase report, which has been used by GROS to produce household estimates for several years, only provides figures at local authority level. In order to produce statistics about occupied and vacant dwellings for smaller geographic areas, GROS collected equivalent data at data zone level. This first analysis of this data was included in last year’s "Estimates of Households and Dwellings" publication. Information at data zone level is available from the Scottish Neighbourhood Statistics website at www.sns.gov.uk.
In a number of cases, the totals from each data zone do not exactly match the local authority figures from ‘Ctaxbase’. For example, some dwellings on the Council Tax system do not have postcode information. The postcode is used to identify the data zone, so a dwelling without a postcode will not be included in the data zone figures. Where there are differences, local authorities have confirmed that the Ctaxbase figures will be more accurate, so the data zone figures are constrained to the Ctaxbase totals for each local authority area.
There has been some difficulty in extracting full data zone information from the software systems used by Clackmannanshire, East Renfrewshire and Fife, so it has not been possible to publish full data for these areas yet. Figures are, however, available for the local authority as a whole, and have been included in this publication.
Definitions of household types
Category |
Description |
All dwellings |
This is the total number of dwellings on the Council Tax valuation list (excluding free-standing private lock-ups and garages). A ’dwelling’ refers to the accommodation itself, for example a house or a flat and includes second homes that are not let out commercially. Caravans count as dwellings if they are someone’s main home. |
Vacant dwellings |
This includes:
|
Second homes |
Dwellings subject to a Council Tax discount of between 10 per cent and 50 per cent due to being second homes. This includes self-catering holiday accommodation available to let for a total of less than 140 days per year. |
Occupied dwellings |
All dwellings, minus those which are vacant or second homes. |
Single adult discounts |
Dwellings subject to a Council Tax discount of 25 per cent. This may include, for example, dwellings with a single adult, dwellings with one adult living with one or more children, or with one or more adults who are 'disregarded' for Council Tax purposes. |
Occupied exemptions |
Dwellings exempt from Council Tax, which are occupied. This includes:
|
When interpreting the figures, it is important to note that not all vacant dwellings may be included here, if they do not receive a Council Tax discount or exemption – for example, short-term vacancies which can arise when people move house. In addition, second homes which are let out for more than 140 days per year are not liable to pay Council Tax – they are instead liable to pay non-domestic rates. This means that such dwellings are not included here, in either the figures on second homes (Tables 7 to 10), or the total number of dwellings (Tables 2, 9 and 10).
4.2 Dwelling estimates from the Assessors' Portal
The Scottish Assessors are responsible for valuing property, for Council Tax purposes. They maintain the web-based Scottish Assessors’ Portal, which contains details of every dwelling in Scotland along with its Council Tax band. More information about the Assessors’ Portal and the role of the Assessors can be found at www.saa.gov.uk.
GROS uses data from the Assessors’ Portal to publish information on the number of dwellings in each data zone in Scotland, along with information about the Council Tax band, type of property, and number of rooms.

A ’dwelling’ refers to the accommodation itself, for example a house or a flat and includes second homes that are not let out commercially. Caravans count as dwellings if they are someone’s main home. |
Council Tax bands |
Each dwelling is placed in one of eight Council Tax bands (A to H), with dwellings in band H being the most expensive. The Council Tax band reflects the Assessor’s opinion of open market value, subject to a number of statutory assumptions. Assessors base their opinion of value on the actual selling prices of similar properties which sold around the valuation date of 1 April 1991. |
Dwellings per hectare |
This variable has been calculated by dividing the total number of dwellings by the area in hectares, as determined by a GROS in-house measure. |
Type of dwelling: |
This information is based on ‘attachment’ – i.e., the type of property in relation to its degree of attachment to surrounding properties. This information has been aggregated into five categories:
|
Number of rooms |
In the Assessors’ Portal, this is defined as the number of habitable rooms (usually bedrooms and living rooms). There may be some differences between different Assessors’ areas in the way in which this information is recorded. For example, differences could arise in the treatment of open plan areas, dining rooms, kitchens and kitchenettes. This information on number of rooms may not always represent the most up to date position as Assessors are only able to reflect physical changes and alterations to dwellings once they have been sold and a reconsideration of the banding has taken place. Information on the number of rooms is not available from the Assessors’ Portal data for Shetland, and it is not separately available for dwellings with seven or more rooms in Dumfries and Galloway. |
4.3 Information on household types from the Scottish Household Survey
The Scottish Household Survey is used to estimate the number of households of each type, in Scotland as a whole (Table 11 and Figure 11). The sample size of this survey is not large enough to provide reliable information on each household type in each local authority area. More information about the Scottish Household Survey is available from www.scotland.gov.uk/shs.
4.4 Urban-rural classification
The Scottish Government produces an urban-rural classification, which is based on settlement size defined by GROS, and accessibility based on drive time analysis. An urban-rural classification is provided for each data zone in Scotland, and this information has been used to analyse the data shown in this publication. There are six urban and rural classifications, shown below:
Scottish Government urban-rural classification |
|
1 Large Urban Areas |
Settlements of over 125,000 people. |
2 Other Urban Areas |
Settlements of 10,000 to 125,000 people. |
3 Accessible Small Towns |
Settlements of between 3,000 and 10,000 people and within 30 minutes drive of a settlement of 10,000 or more. |
4 Remote Small Towns |
Settlements of between 3,000 and 10,000 people and with a drive time of over 30 minutes to a settlement of 10,000 or more. |
5 Accessible Rural |
Settlements of less than 3,000 people and within 30 minutes drive of a settlement of 10,000 or more. |
6 Remote Rural |
Settlements of less than 3,000 people and with a drive time of over 30 minutes to a settlement of 10,000 or more. |

4.5 Scottish Index of Multiple Deprivation, SIMD
The Scottish Index of Multiple Deprivation (SIMD) is produced by the Scottish Government to identify concentrations of deprivation across Scotland in a consistent way. It is based on 37 indicators in seven domains: Current Income, Employment, Health, Education Skills and Training, Geographic Access to Services, Housing and Crime. An SIMD rank is produced for every data zone in Scotland. Based on this, the SIMD decile is produced, from one (most deprived) to ten (least deprived). This information, from the 2006 SIMD, has been used to analyse the data shown in this publication.
More information about the SIMD is available from the Scottish Government website at http://www.scotland.gov.uk/Topics/Statistics/SIMD/Overview.
4.6 Strategic Development Planning Authority (SDPA) areas
SDPA areas cover the four largest city regions around Aberdeen, Dundee, Edinburgh and Glasgow. In November 2008 the following SDPA areas were agreed by Ministers:
Glasgow and the Clyde Valley Strategic Development Plan Area (Glasgow & Clyde Valley SDPA)
East Dunbartonshire, East Renfrewshire, Glasgow City, Inverclyde, North Lanarkshire, Renfrewshire, South Lanarkshire and West Dunbartonshire (excepting the part of West Dunbartonshire Council that forms part of the Loch Lomond & the Trossachs National Park).
Aberdeen City and Shire Strategic Development Plan Area (Aberdeen City and Shire SDPA)
Aberdeen City and Aberdeenshire (excepting the part of Aberdeenshire Council that forms part of the Cairngorms National Park).
Edinburgh and South East Scotland Strategic Development Plan Area (SESplan SDPA)
City of Edinburgh, East Lothian, Midlothian, Scottish Borders, West Lothian and south Fife (Kirkcaldy, Mid Fife and Dunfermline local plan areas).
Dundee, Perth, Angus and North Fife Strategic Development Plan Area (TAYplan SDPA)
Angus (excepting the part of Angus Council that forms part of the Cairngorms
National Park), Dundee City, Perth & Kinross (excepting the part of Perth & Kinross Council that forms part of the Loch Lomond & the Trossachs National Park) and north Fife (St Andrews and North Fife local plan areas).
Information about the data zones which have been used produce the SDPA figures included in this publication is in Annex A.
Further information about SDPAs, including maps showing the boundaries of each SDPA, is available in the Scottish Government’s Planning Circular 3/08: http://www.scotland.gov.uk/Publications/2008/11/25145654/15.
In 2008, GROS produced, for the first time, population and household projections for Scotland’s National Parks using 2006-based projections. Further information about these projections and the data zones which make up the National Park projections are available from http://www.nrscotland.gov.uk/statistics-and-data/statistics/statistics-by-theme/population/population-projections/population-projections-for-scotland's-sdp-areas-and-national-parks/national-parks-2006-based. The same aggregations of data zones have been used to produce the National Park statistics shown in this publication.
