Things you need to know
The Census is planned and carried out by the Office for National Statistics (ONS) every 10 years in England and Wales. The last Census was held in March 2011.
The Census is the only survey to give a detailed picture of the whole population of England and Wales. It makes it possible to compare different parts of the country as all households are asked the same questions within the same time period.
For the 2011 Census, around 25 million pre-addressed questionnaires were posted out to all households using a specially developed national address register. Households could return their questionnaire by post or complete it online. Census employees delivered questionnaires by hand to people living in residential care homes, hospitals, hostels, boarding schools, university halls of residence, mobile home parks, military bases and other communal establishments.
94% of households completed the 2011 Census. Of those, 97% answered the question about ethnicity.
Age can affect a number of outcomes. Younger people are more likely to be in rented accommodation, for example, whereas older people are more likely to be in poor health.
Age can also have an influence on, among other things, whether or not they are employed and which socio-economic group they are in.
All percentages have been calculated using unrounded data. As a result, the figures quoted in the commentary may not match those shown in the tables.
What the data measures
This data shows the age profiles for different ethnic groups in England and Wales. It shows the median age for each broad ethnic group, and the percentage of the population in each age group (for example, 0 to 4 years old, 5 to 9 years, 10 to 14 years, and so on) for specific ethnic groups.
The Census is held in England and Wales every 10 years to collect data on every person living in the country on a specific date.
The Census provides the only source of directly comparable statistics for both small areas and minority population groups across England and Wales.
The information the Census provides allows central and local government, health authorities and many other organisations to plan housing, education, health and transport services for years to come.

Summary of Age groups Average age by ethnicity Summary
This data uses the ‘median’ for working out the average age for each ethnic group. The median is the middle point of a range of numbers that are arranged in order of size from lowest to highest.
This data shows that:
- at the time of the 2011 Census, the median age of the population of England and Wales was 39 years
- the White ethnic group had the highest median age (at 41 years), and the Mixed group had the lowest (at 18 years)
- the Asian, Black and Other ethnic groups had similar median ages at 30, 30, and 29 years respectively

Summary of Age groups Black ethnic groups: age profile Summary
This data shows that:
- at the time of the 2011 Census, 30.4% of the population of England and Wales identifying as Black were aged under 18 years, 35.2% were aged 18 to 39 years, 26.4% were aged 40 to 59 years, and 8.1% were aged 60 years and over
- the Black African group had a younger age profile than the Black Caribbean group, partly due to different immigration patterns – the first large wave of immigrants from the Caribbean was in the 1950s and 1960s, and most of their children were aged 40 to 55 years at the 2011 Census (accounting for nearly 30% of this ethnic group); the more recent immigration of Black Africans explains why 29% of people in this ethnic group were aged 25 to 39 years at the Census
- out of all Black ethnic groups, the Other Black group had the highest percentage of people under 18 years (at 41.7%), and the Black Caribbean group had the lowest (at 20.1%)
- the Black Caribbean ethnic group had the highest percentage of people aged 65 years and over (at 13.9%), and the Black African group had the lowest (at 2.4%)
- 26% of people from the Other Black group were under 10 years old, compared with 20% of the Black African group and 10% of the Black Caribbean group

Summary of Age groups Mixed ethnic groups: age profile Summary
This data shows that:
- at the time of the 2011 Census, 49.3% of the population of England and Wales identifying as having Mixed ethnicity were aged under 18 years, 33.4% were aged 18 to 39 years, 13.2% were aged 40 to 59 years, and 4.1% were aged 60 years and over
- 52.6% of Mixed White and Black African people were aged under 18 years (the highest percentage out of all Mixed ethnicity groups), followed by 51.4% of Mixed White and Asian people
- nearly 1 in 5 (18.0%) of people with Mixed ethnicity were under 5 years old, with the figure reaching 21.9% in the Mixed White and Black African group
- these figures may reflect how Mixed ethnicity relationships have become more common in recent years, with the children of these relationships forming the majority of this ethnic group
- the percentage of the population aged 65 and over was small among Mixed ethnic groups, accounting for 1.9% of Mixed White and Black African people

Summary of Age groups White ethnic groups: age profile Summary

9. Methodology
All households in England and Wales received a census questionnaire through the post. The questionnaire was accompanied by an information leaflet and a pre-paid envelope for return by post.
Households in Wales received both English language and Welsh language questionnaires, and information leaflets.
Householders could complete their questionnaire and return it by post or they could complete the census questionnaire online. Each paper questionnaire had an internet access code which was unique to that household which enabled the householder to complete their questionnaire online.
Questionnaires returned via the post, or through the internet, were receipted daily and this information uploaded onto the questionnaire tracking (QT) system. This enabled the identification of households for follow-up where a questionnaire had not been returned or completed online.
Communal establishments, for example, managed accommodation (such as care homes) and special groups (such as travellers) had their census questionnaires hand delivered.
In communal establishments, questionnaires were collected by the special enumerators and transferred to the census processing site via the census coordinators. Individuals within communal establishments also had the option of completing their questionnaire online following the same process as that used by households.
2011 Census questions There were 56 questions on the 2011 Census questionnaire: 14 about the household and its accommodation and 42 for each member of the household. For those living in Wales, there was a Welsh and English version of the questionnaire, and an extra question about the Welsh language.
Questions included those about work, health, national identity, passports held, ethnic background, education, second homes, language, religion and marital status.
Previous Census questionnaires can be seen in the 200 years of the Census section.
Suppression rules and disclosure control
The ONS uses a number of ways to protect the confidentiality of individuals and households, including:
- record swapping, where small numbers of records are swapped between geographical areas
- restricting the amount of detail shown in published data, particularly at low level geographies like local authorities
