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.

Findings from the Coronavirus (COVID-19) Infection Survey for Scotland.

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

National Statistics Socio-economic Classification (NS-SeC)

The National Statistics Socio-economic Classification (NS-SeC) provides an indication of socio-economic position based on occupation.

To assign a person aged 16 and over 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.

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 2016

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.

Ward Level Population estimates

New 2014 Ward boundary estimates

Ward boundary changes in May 2014 only affected three London boroughs - Hackney, Kensington and Chelsea, and Tower Hamlets. The estimates between 2001-2013 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. From 2014 onwards, ONS began publishing official estimates for the new ward boundaries.

Approximated social grade

Social Grade is the socio-economic classification used by the Market Research and Marketing Industries, most often in the analysis of spending habits and consumer attitudes. Although it is not possible to allocate Social Grade precisely from information collected by the 2011 Census, the Market Research Society has developed a method for using Census information to provide a good approximation of Social Grade.

Abstract copyright UK Data Service and data collection copyright owner. A census of population is held every ten years in the UK, in England and Wales it is undertaken by the Office for National Statistics (ONS), in Scotland by the National Records of Scotland (NRS) and in Northern Ireland by the Northern Ireland Statistics and Research Agency (NISRA). In England, Wales and Northern Ireland the latest census was taken on Sunday 21st March 2021. Due to issues around COVID-19, the census in Scotland was held a year later on 28th June 2022. The census asks questions about you, your household and your home. In doing so, it helps to build a detailed snapshot of our society. Information from the census helps the government and local authorities to plan and fund local services, such as education, doctors' surgeries and roads. Topics covered by the data released by the Census agencies include - Demography and migration, UK armed forces veterans, ethnicity, national identity, language, religion, labour market, housing, sexual orientation, gender identity, education, health, disability and unpaid care. The data in this series covers aggregate data at geographies from country level down to Output Area. Due to disclosure control (data can be blurred, changed or withheld to protect anonymity) not all datasets are available at all levels.

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