This dataset provides the percentage of the population in Wales in each of several broad age bands since Census 1871 by sex. Data for individual local authorities are also included from 2001 onwards. It should be noted that for mid-2020 there are some definitional changes (particularly affecting the migration components) compared with mid-2019 population estimates data, and it is advised users read the Quality and Methodology Information section on the Office for National Statistics website. For Wales, the mid-2021 population estimates are the first population estimates to be based on Census 2021. Internal migration estimates for mid-2023 have been produced using a different method to previous years, following a change to the variables available in the Higher Education Statistics Agency (HESA) data.

The Office for National Statistics (ONS) produces annual estimates of the resident population of England and Wales at 30 June every year. The most authoritative population estimates come from the census, which takes place every 10 years in the UK. Population estimates from a census are updated each year to produce mid-year population estimates (MYEs), which are broken down by local authority, sex and age. More detailed information on the methods used to generate the mid-year population estimates can be found here.

For further information on the usefulness of the data and guidance on small area geographies please see here.The currency of this data is 2021.

Methodology

The total and 5-year breakdown population counts are reproduced directly from the source data. The age range estimates have been calculated from the published estimates by single year of age. The percentages are calculated using the gender specific (total, female or male) total population count as a denominator except in the case of the male and female total population where the total population is used to give female and male proportions.

This dataset will be updated annually, in two releases.

Experimental statistics for population estimates by religion broken down into age and sex at a national regional level for England and Wales.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by sex and single year of age. The estimates are as at Census Day, 21 March 2021.

The classifications for the datasets TS009 Sex by single year of age and RM200 Sex by single year of age (detailed) are the same. However, RM200 has data available at the lower geographies of:

• Lower layer Super Output Areas (LSOAs)
• Middle layer Super Output Areas (MSOAs)
• Electoral wards and divisions
• Westminster parliamentary constituencies

Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands. Read more about this quality notice.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Coverage

Census 2021 statistics are published for the whole of England and Wales. Data are also available in these geographic types:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Age

A person’s age on Census Day, 21 March 2021 in England and Wales. 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”.

Population estimates for Lower Layer and Middle Layer Super Output Areas in England and Wales by age and sex. These estimates are consistent with the local authority population estimates.

The methodology used to produce the LSOA and MSOA estimates differs to the method used to produce the local authority mid-year estimates.

About this dataset

Context

The dataset tabulates the population of Wales by gender across 18 age groups. It lists the male and female population in each age group along with the gender ratio for Wales. The dataset can be utilized to understand the population distribution of Wales by gender and age. For example, using this dataset, we can identify the largest age group for both Men and Women in Wales. Additionally, it can be used to see how the gender ratio changes from birth to senior most age group and male to female ratio across each age group for Wales.

Key observations

Largest age group (population): Male # 25-29 years (170) | Female # 55-59 years (177). Source: U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates.

Content

Scope of gender :

Please note that American Community Survey asks a question about the respondents current sex, but not about gender, sexual orientation, or sex at birth. The question is intended to capture data for biological sex, not gender. Respondents are supposed to respond with the answer as either of Male or Female. Our research and this dataset mirrors the data reported as Male and Female for gender distribution analysis.

Variables / Data Columns

• Age Group: This column displays the age group for the Wales population analysis. Total expected values are 18 and are define above in the age groups section.

Important notice

The Office for Statistics Regulation confirmed on 12/09/2024 that the gender identity estimates from Census 2021 are no longer accredited official statistics and are classified as official statistics in development.

For further information please see: Sexual orientation and gender identity quality information for Census 2021

These datasets provide Census 2021 estimates that classify usual residents aged 16 years and over in England and Wales for gender identity by sex, gender identity by age and gender identity by sex and age.

Gender identity

Gender identity refers to a person's sense of their own gender, whether male, female or another category such as non-binary. This may or may not be the same as their sex registered at birth.

Non-binary

Someone who is non-binary does not identify with the binary categories of man and woman. In these results the category includes people who identified with the specific term "non-binary" or variants thereon. However, those who used other terms to describe an identity that was neither specifically man nor woman have been classed in "All other gender identities".

Sex

This is the sex recorded by the person completing the census. The options were "Female" and "Male".

Trans

An umbrella term used to refer to people whose gender identity is different from their sex registered at birth. This includes people who identify as a trans man, trans woman, non-binary or with another minority gender identity.

Trans man

A trans man is someone who was registered female at birth, but now identifies as a man.

Trans woman

A trans woman is someone who was registered male at birth, but now identifies as a woman.

Usual resident

A usual resident is anyone who on Census Day, 21 March 2021, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

Notes:

• To ensure that individuals cannot be identified in the data, population counts have been rounded to the nearest five and counts under 10 have been suppressed.

• Percentages have been calculated using rounded data.
