Dwelling Disrepair (Scottish House Condition Survey)
The proportion of households with any (basic) disrepair, disrepair to critical elements, urgent disrepair or extensive disrepair to their dwelling, by dwelling types, household characteristics and council area. Derived from the Scottish House Condition Survey (SHCS).
Data
Dwelling Disrepair (Scottish House Condition Survey)
Description
Statistics presented here are based on the Scottish House Condition Survey (SHCS), an annual national survey of Scotland's housing stock, which forms part of the Scottish Household Survey (SHS).
The annual SHCS Key Findings report presents the latest national data for key measures of energy efficiency, fuel poverty, energy perceptions and housing quality. The local authority breakdowns provide key indicators at local authority level relating to different household and dwelling types. However three years of data are combined to mitigate the smaller sample sizes involved when analysing sub-national geographies. Therefore, it is important to be aware that for these aggregate time periods:
1. The three year average national rates will not match those for single years (also found in the main Key Findings reports).
2. Each three year average is a snapshot in time, and because of overlapping years, consecutive releases should not be used to quantify changes in time.
3. Notwithstanding the aggregation of three years of data, smaller base sub-samples mean that confidence intervals for different geographies, household and dwelling types will be larger than those reported in the annual Key Findings report.
The SHCS quantifies disrepair for a wide range of building elements. The type of disrepair is categorised into four broad classifications:
1. Any (or Basic) disrepair: This is the minimum threshold of disrepair measured in the SHCS and relates to any damage where a building element requires some repair beyond routine maintenance. It is the most comprehensive category covering all types of disrepair, however minor, and encompasses all other types of disrepair
2. Extensive disrepair: To be described as extensive, the damage must cover at least a fifth (20%) or more of the building element area. This category is different from the severity of damage as described by the next two categories, urgent and critical, and can be applied to any of the other 3 categories of disrepair.
3. Urgent disrepair: This relates to cases requiring immediate repair to prevent further damage or health and safety risk to occupants. Urgency of disrepair is only assessed for external and common elements.
4. Critical element disrepair: This refers to disrepair to building elements central to weather-tightness, structural stability and preventing deterioration of the property. These elements are listed in section 7.8.7.3 of the 2016 Key Findings Report. There is some overlap in the building elements assessed under this category and those assessed for urgent disrepair. Not all disrepair to critical elements is necessarily considered urgent by the surveyor.
Where a table shows missing values, the data has either been suppressed on disclosure control grounds, or because there were no sampled cases.

Consistency
Because of a routing error tenure information is not available for a small number of cases in the 2012 and 2013 surveys (46 in 2012, 42 in 2013). This was rectified for the 2014 fieldwork and the full sample has been used when reporting on tenure for subsequent years.
Consequently, these cases are excluded from tenure breakdowns for data encompassing these years and also applies to data covering the 2010-2012, 2011-2013, 2012-2014 and 2013-2015 periods.
In 2015, a uniform retirement age of 65 and above was introduced when building "Older" Household Types. All years in these data from 2010 onwards been harmonised to match this Household Type definition, and will not necessarily match the definition used in earlier Key Findings reports. Therefore, please refer to the 2016 SHCS Key Findings Report for a complete definition of the Household Types used in this data release.
Timeliness
The release of SHCS Local Authority data lags the publication of the annual SHCS Key Findings Report to allow for an aggregation of three years' worth of data. The data are published in the first instance on the SHCS website, and the Open Data Platform will be updated as soon as possible after this. A summary document highlighting key findings of the 2014-2016 Local Authority release can also be found on the SHCS website SHCS website.

Accuracy
From 2012 onwards, the SHCS is a module of the Scottish Household Survey (SHS). In general, around one third of respondents to the SHS are invited to participate in a follow-up inspection by SHCS building surveyors.
The SHCS is a sample survey. All survey figures are estimates of the true prevalence within the population and will contain some error associated with sampling variability. The likely size of such variability can be identified, by taking account of the size and design of the sample. Users may estimate the margin of error by using a statistical significance tool included with the version published on the SHCS website.
In addition to sampling variability, there are other sources of uncertainty, such as those arising from incomplete responses or failure to secure participation in the survey from each sampled household. Where non-response is not random, i.e. some types of household are less likely to participate than others, bias is introduced into the survey data. Such errors have not been quantified in the main Key Findings reports, or for these aggregated years data.
In general, the smaller the sample size, the greater the likelihood the estimate could be misleading, so more care must be taken when using smaller subsets of the survey sample for analysis. In order to reach a sufficient sample size for local authorities, it is necessary three years' worth of data are combined.
For a complete description of the survey's structure and its reliability, please refer to the SHCS Methodology Notes published on the SHCS website.

Additional details
Revisions
Routine revisions and updates are applied to previous years as methodologies are improved or indicator definitions are changed. A full list of revision and updates can be accessed on the SHCS Revisions and Corrections website.
Where a table shows missing values, the data has either been suppressed on disclosure control grounds, or there were no sampled cases.
Confidentiality policy
Where an estimate is representative of two or fewer sampled cases, or the base sample is fewer than 30 cases, the statistic is suppressed.
