6. Background Notes
6.1 Data sources and validation
The main data source for this report is the Scottish Government CTR data extract (some other data sources have been used to provide contextual data, such as the number of chargeable dwellings. Where this is the case the relevant source has been provided.) Since the CTR scheme was introduced on 1 st April 2013, the Scottish Government have asked all local authorities to provide individual record level extracts on a monthly basis to enable monitoring of the number of recipients and weekly income foregone estimates. Local authorities' continued cooperation in providing this data is gratefully acknowledged.
Local authorities are asked to extract their data on a specified date (the count date) although local authorities can provide data up to a week after that date. This means the extract provides a snapshot for each month, and so may include CTR applications that are subsequently revised by local authorities. The CTR extract count dates for April 2016 to March 2017 were:
There are two types of records contained within the CTR data extract which might feed into the statistics:
1. 'D' records: those that were 'live' on the count date; and
2. 'C' records: those that have been closed since the previous count date. They are used to identify short term claims ( i.e. those that were live on the count date for a specific month but not on the count date for the months on either side) and 'D' records that haven't actually closed before the count date.
These records do not contain information on total weekly award amount and so, to enable total weekly figures to be estimated, it is assumed that the weekly award was the same as the average weekly award for each local authority and benefit type for the given month (based on the 'D' records).
As part of the quality assurance procedure, the Scottish Government carries out validation checks on incoming data to identify possible errors. Potential problems are identified in a number of ways, including comparing the data received to other known sources; data from previous months and years; and data from other local authorities. Where appropriate, views are also sought from policy colleagues - for example, where a change in the data may be attributable to a policy change. To ensure the data are of a high quality, the Scottish Government then works with the relevant local authorities to resolve any data issues identified.
A full methodology guide is available at: http://www.gov.scot/Topics/Statistics/Browse/Local-Government-Finance/Methodology/Ctaxreductionmethod.
For information on total CTR income foregone for the year (as in Table 4 of this publication), CTRR and LFRs have been used. These are aggregate returns which collect data from local authorities on the total amounts of Council Tax billed, including the amounts of CTR applied. CTRR and LFRs give better overall estimates of total reductions in liabilities than the monthly extracts as they represent the billing and award position for the year as a whole.
