Ward level Population Estimates

Custom Age Range Tool

An Excel tool is available that uses Single year of age data that enables users to select any age range required.

ONS policy is to publish population estimates rounded to at least the nearest hundred persons. Estimates by single year of age, and the detailed components of change are provided in units to facilitate further calculations. They cannot be guaranteed to be as exact as the level of detail implied by unit figures.

Estimates are calculated by single year of age but these figures are less reliable and ONS advise that they should be aggregated to at least five-year age groupings for use in further calculations, onwards circulation, or for presentation purposes. (Splitting into 0 year olds and 1-4 year olds is an acceptable exception).

ONS mid-year population estimates data by 5 year age groups going all the way back to 1981, are available on the NOMIS website.

Analysis and Extracts

Period life expectancy by age and sex for Scotland. Each national life table is based on population estimates, births and deaths for a period of three consecutive years. Tables are published annually.

This publication will complement the main Office for National Statistics (ONS) regional labour market publication. The estimates are compiled by ONS and will be based on the rolling quarterly data from the Labour Force Survey. It will focus on the latest available youth unemployment data covering the period August - October 2011 and look at the change over the past year. A time series of data back to January - March 2008 will also be published.

This file contains the National Statistics Postcode Lookup (NSPL) for the United Kingdom as at August 2025 in Comma Separated Variable (CSV) and ASCII text (TXT) formats. To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland. It supports the production of area-based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

Dataset population: Persons aged 16 and over

General health

General health is a self-assessment of a person's general state of health. People were asked to assess whether their health was very good, good, fair, bad or very bad.

For England and Wales, this assessment is not based on a person's health over any specified period of time.

NS-SeC

The National Statistics Socio-economic Classification (NS-SeC) provides an indication of socio-economic position based on occupation. It is an Office for National Statistics standard classification.

To assign a person aged 16 to 74 to an NS-SeC category, their occupation title is combined with information about their employment status, whether they are employed or self-employed and whether or not they supervise other employees. Full-time students are recorded in the 'full-time students' category regardless of whether they are economically active or not.

The rebased version of NS-SeC used in census results uses occupation coded to SOC2010. Information about the classification is available here: NS-SEC rebased on SOC2010.

For 'Long-term unemployed', the year last worked is 2009 or earlier. In 2011 Census results, because the census did not ask a question about the number of employees at a person's workplace, the reduced method of deriving NS-SeC (which does not require this information) is used.

This dataset provides Census 2022 estimates for National Statistics Socio-economic Classification (NS-SeC) of people aged 16 and over by sex by age (in 16 categories) in Scotland.

Age

A person's age on Census Day, 20 March 2022. Infants aged under 1 year are classified as 0 years of age.

Sex

This is the sex recorded by the person completing the census. The options were "Female" and "Male". Guidance on answering the question can be found here

Workplace Zones (WZs) are a new output geography, initially produced using workplace data from the 2011 Census for England and Wales rather than the UK as a whole. They are designed to supplement the Output Area (OA) and Super Output Area (LSOA and MSOA) geographies that were introduced with the 2001 Census, and have been constructed from OAs, or sub-divisions of these called postcode-level building-blocks (PCBBs). While OAs are designed to contain consistent numbers of persons based on where they live, WZs are designed to contain consistent numbers of workers, based on where people work. Following publication of WZs for England and Wales, coverage has subsequently been extended to include Scotland and Northern Ireland using 2011 Census data to create a UK set of WZs produced by the Office for National Statistics (ONS) on behalf of National Records of Scotland (NRS) and the Northern Ireland Statistics and Research Agency (NISRA). WZs are designed to be a more suitable output geography for publishing workplace statistics.

Excel Age-Range creator for Office for National Statistics (ONS) Mid year population estimates (MYE) covering each year between 1999 and 2014

https://londondatastore-upload.s3.amazonaws.com/mye-custom-tool.JPG" alt="" />

These files take into account the revised estimates for 2002-2010 released in April 2013 down to Local Authority level and the post 2011 estimates based on the Census results. Scotland and Northern Ireland data has not been revised, so Great Britain and United Kingdom totals comprise the original data for these plus revised England and Wales figures.

This Excel based tool enables users to query the single year of age raw data so that any age range can easily be calculated without having to carry out often complex, and time consuming formulas that could also be open to human error. Simply select the lower and upper age range for both males and females and the spreadsheet will return the total population for the range. Please adhere to the terms and conditions of supply contained within the file.

Tip: You can copy and paste the rows you are interested in to another worksheet by using the filters at the top of the columns and then select all by pressing Ctrl+A. Then simply copy and paste the cells to a new location.

New 2014 Ward boundary estimates

This data is only for wards in the three London boroughs that changed their ward boundaries in May 2014. The estimates in this spreadsheet have been calculated by the GLA by taking the proportion of a the old ward that falls within the new ward based on the proportion of population living in each area at the 2011 Census. Therefore, these estimates are purely indicative and are not official statistics and not endorsed by ONS.

Ethnic group classifies people according to their own perceived ethnic group and cultural background.

For Northern Ireland only, this table reports the categories for which there are 10 or more usual residents. Where there are fewer than 10 usual residents for any category, these have been reported in a residual group which may or may not contain 10 or more usual residents in total.
