About the Demographic Information

This page combines information for all postcodes within the postcode district SE21. The information on housing, people, culture, employment and education that is displayed about SE21 is based on the last census performed in the UK in 2021 (2022 in Scotland). They are performed once every 10 years. The figures are representative of the local area, not a specific street address or row of houses.

Housing Types

Housing Tenure Back to Top

Housing Occupancy Back to Top

This data lists the total number of residents normally resident within each household. The figures do not record under- or over-occupancy.

Household Composition Back to Top

Household Deprivation Back to Top

Household deprivation was measured against four dimensions for the 2021 census - employment, education, health/disability, and overcrowding.

Gender

Age Groups Back to Top

Across the UK as a whole, the median age is 40.7 years. In general, inner city areas show high concentrations of people aged 18-30, suburbs show larger numbers of small children and adults aged 30-50, and rural and small towns are more popular with older workers and retirees. Many poorer areas lack a majority age group, which is due in part to the people in that area being constrained by circumstance rather than being able to choose where to retire, raise a family or grow up.

Relationship Status Back to Top

Figures for relationship status do not include those aged under 16, or those family members aged 16-18 who are in full-time education. Following the Civil Partnership Act that came into force in 2019, census figures for 2021/2022 no longer categorise same sex relationships as a separate category. Civil partnerships are now included within the figures for the other categories (Married, Divorced and so forth).

Health Back to Top

Health in the UK is strongly tied to age as you would expect, but the affluence of a neighbourhood also has strong influence, with deprived areas often showing poorer standards of health.

Overall, the UK considers itself to be healthy - 81.6% of residents of the United Kingdom rated their health as Very Good or Good.

Education & Qualifications Back to Top

At the time of the 2021/22 census, across the UK 22.9% of residents had no qualification, 10.3% had 1-4 GCSEs as their highest qualification, 13.2% had 5+ GCSEs and 1-2 A/AS-Levels, 16.6% had 2+ A-Levels, 33.6% had a degree (or similar), and 5.6% had an apprenticeship.

Ethnic Group

Country of Birth Back to Top

Length of Residence Back to Top

The length of time a person has been resident in the UK has been calculated from the time a resident most recently arrived in the UK (excluding holidays/short stays outside the UK). However, residents that were born in the UK but emigrated and then later returned will still be counted as "Born in the United Kingdom".

Passport(s) Held Back to Top

Note that an individual may hold one or more passports.

Religion Back to Top

Economic Activity

Figures for economic activity do not include those aged under 16, or those family members aged 16-18 who are in full-time education. The 2021/22 census occurred during period of depressed economic activity due to the COVID-19 pandemic. As a result, care should be taken in interpreting figures relating to labour market participation.

Occupation Group Back to Top

This data is based on resident aged 16+ on census day 2021/22, who were in employment. The categories are taken from the Standard Occupational Classification (SOC) 2020.

Socio-Economic Classification

Classifications are assigned based on an algorithm created by the National Statistics Agency, called the Socio-economic Classification (NS-SEC). The 2021/22 census occurred during period of depressed economic activity due to the COVID-19 pandemic. As a result, care should be taken in interpreting figures relating to labour market participation.
