Mr. Hoyle: To ask the Chancellor of the Exchequer what his estimate is of the population of (a) Lancashire and (b) Chorley constituency; and what assessment he has made of the likely population growth in each of the next 10 years. 
The Office for National Statistics does not currently produce mid-year population estimates or projections on parliamentary constituency boundaries. However, in the case of Chorley, the parliamentary constituency currently has the same boundaries as Chorley borough council and so can be provided.
The most recent set of population projections for England are 2003-based and use local trends in births, deaths and migration over the reference period 1999 to 2003 to formulate assumptions on levels of fertility, mortality and migration for future years.
|Mid-year population estimate|
Dr. Francis: To ask the Chancellor of the Exchequer what assessment he has made of the accuracy of the most recent population statistics provided by the Office for National Statistics for Aberavon and Neath Port Talbot. 
As National Statistician, I have been asked to reply to your recent Parliamentary Question asking what assessment has been made of the accuracy of the most recent population figures provided by the Office for National Statistics for Aberavon and Neath Port Talbot. (53612)
Population estimates are calculated using an internationally respected methodology. Further information can be found in the detailed methodology guide Making a population estimate in England and Wales". This is published here: http://www.statistics.gov.uk/StatBase/Product. asp?vlnk=575
It is becoming increasingly difficult to estimate the size of the population because of changes in society, which include increased mobility and different living arrangements. The decennial Census provides a benchmark against which national and sub-national population estimates can be assessed. Substantial work has been done on the difference between mid-year population estimates and the 2001 Census. This work is summarised in the final report of the 2004 Local Authority Population Studies, which can be found here: http://www.statistics.gov.uk/downloads/theme_population/LAStudy_FullReport.pdf
These studies confirmed that the 2001 Census had worked well in most areas, including Aberavon and Neath Port Talbot, but there were a few cases where the adjustment for under-enumeration was not able to adjust sufficiently for exceptional circumstances. This work, together with revised international migration estimates, accounted for a large proportion of the initial 1.1 million difference between mid year estimates and the Census; reducing the difference to a little over 0.2 million
In addition, extensive annual quality assurance is undertaken in order to ensure the accuracy of the annual mid-year estimates. Quality assurance starts with detailed checking of the source data used in the components of change (birth, deaths, etc.). Procedures are then in place to ensure that these data sources are correctly processed when deriving the estimates. The calculated national and sub-national estimates, for all 376 local authorities in England and Wales, are then subject to a further set of quality assurance procedures before they are published. These procedures include reviews of sex ratios and age profiles, comparisons of change over time, and comparisons of fertility and mortality rates. Substantial effort has already been undertaken, in recent years, to improve the quality assurance of population estimates.
ONS is also now investing substantially in a project to Improve Migration and Population Statistics (IMPS). (More information on this project can be found at: www.statistics.gov.uk/IMPS). The key aims of this project are to reduce the size of the difference between the 2011 Census results and the mid-year estimates and to better understand any difference that does remain. As part of this project, we are developing a data comparator tool to enable us to compare the annual mid-year estimates against a range of administrative sources. This work is ongoing and the results will inform our understanding of the accuracy of the mid-year population estimates. The tool was trialled in the mid-2004 population estimates, which were published in August 2005.
Another strand of the IMPS project is a review of the quality assurance procedures that are currently in place for population estimates. One of the aims of this review is to assess what improvements can be made to existing procedures, and determine whether additional quality assurance is required.
ONS also produces population projections for each local authority area. The methodology used in the production of the subnational population projections is an established and recognised methodology. Subnational population projections undergo extensive quality assurance before publication. In addition, local authorities and health authorities are consulted on the first year of migration assumptions used as the baseline trend for migration.
Population estimates and projections are supplied to the ODPM. I understand that ODPM make checks to ensure that the data as provided by the ONS have been correctly entered into their calculations for allocating Formula Grant to local authorities. Otherwise, they do not make any assessment of accuracy of the data supplied, as this responsibility lies with the ONS.
Mr. Keith Simpson: To ask the Chancellor of the Exchequer (1) if he will break down the (a) main estimate and (b) winter supplementary estimate provision for the Security and Intelligence Agencies Request for Resources 1 by (i) new cash and (ii) non-cash for financial years 200506; 
(2) if he will break down the (a) main estimate, (b) winter supplementary estimate and (c) spring supplementary estimate provision for the Security and Intelligence Agencies Request for Resources 1 by (i) new cash and (ii) non-cash for financial years 19992000 to 200405. 
Mr. Des Browne
[holding answer 13 February 2006]: Resource-based estimates were published across Government for the first time in 200102. Government resource accounting and budgeting continues to develop and this includes the introduction of current concepts such as non-cash and near-cash. Given the structure of

estimates prior to 200102 it is not possible to calculate non-cash and near-cash figures from these estimates. The following tables provides non-cash and near-cash
27 Feb 2006 : Column 348W
figures for the published estimates up to, and including, 200102 (there was no SIA spring supplementary in 200102):
|Resource Near cash||989,926||935,800||957,975||931,845||90,6095||613,412||579,189||541,740|
|Resource Near cash||854,585||841,327||781,110||0||784,825||775,944|
Mr. Keith Simpson: To ask the Chancellor of the Exchequer if he will break down the Security and Intelligence Agencies Request for Resources 1 outturn by (i) new cash and (ii) non-cash for financial years 200405. 
Mr. Des Browne [holding answer 13 February 2006]: At the last supplementary round the near-cash and non-cash figures for the Security and Intelligence Agencies Request for Resources 1 outturn 200405 are around £1,000,000,000 and £110,000,000 respectively.
