128,985 of South Cambridgeshire’s 162,117 residents identified as White British at the 2021 Census. The projection takes that share from 79.5% to 55.4% by 2051. Interpolated between projection decades, so the year is approximate.

Ethnic composition trajectory

Solid to 2021 is Census. Dashed after that is the model, which was scored against Census 2021 before publication: a mean absolute error of 1.56 percentage points per decade and a bias of +0.05 points, close to unbiased. The shaded band is the 80% interval for White British share.

Two independent models trained on the same Census base disagree by 0.4pp on White British share in South Cambridgeshire by 2051. HP captures observed 2011 to 2021 cohort dynamics. The cohort-component model adds explicit fertility assumptions that pull projections toward the national mean. The chart above shows HP. See the methodology for why both numbers are published.

DWP National Insurance number allocations to adult overseas nationals (Stat-Xplore NINO database).. NINo registrations measure new arrivals into the National Insurance system, not total foreign-born population. A NINo is allocated when an overseas national requests one, usually to start work or claim benefits, so the figure misses students and dependants who never enter the labour market. Small (LA × nationality) cells are suppressed by Stat-Xplore for disclosure control.

Arrivals over the last 24 years

Annual NINo registrations to adults from overseas in South Cambridgeshire from 2002 to 2025, alongside the UK total for context. The peak year was 2022 (2,188 registrations). Total over the full period: 22,901 registrations.

DWP Stat-Xplore, NINO Registrations to Adult Overseas Nationals Entering the UK (Ninos cube), aggregated per calendar year by summing the four constituent quarters. Geography: ONS LA codes. Counts are NEW NINo registrations per calendar year. A NINo is issued once per person at the point of first work or claim, so this is a flow measure, not a stock. People who arrive but never register (some students, dependants, retirees) are excluded. Late registrations show in a later year than the year of arrival. Pre-2010 figures used a different administrative system; series is comparable but small methodological revisions to the early years are possible.

DWP Stat-Xplore Ninos cube, LA × Age band × Sex, rolling year ending Q4 2025 (Jan-Dec 2025 calendar year). Counts are NEW NINo registrations to adult overseas nationals. Age is age at NINo registration, not age at arrival. The registration may follow arrival by months. 'Less than 18' is rare in this dataset because the published Ninos series is filtered to adult overseas nationals; values reflect young workers/claimants close to 18. 'Unknown' age is a small residual.

Why people are coming

For each of the top arriving nationalities in South Cambridgeshire, this is the national mix of visa routes used in 2025. It shows whether arrivals from that country are typically students, workers, on family routes (including refugee family reunion), or in some other category. Local-authority breakdowns of visa routes are not published, so we apply the national mix at nationality level.

No entry-clearance visa data. United States is non-visa-national or in the Common Travel Area, so visa-route mix is not informative for this country. NINo flow is the better signal.

Home Office, Immigration system statistics, year ending June 2026; Vis_D02 (Entry clearance visa outcomes by nationality, visa type, and outcome). Joined with DWP Stat-Xplore NINo registrations rolling year ending Q4 2025. Visa grants are issued at the point of entry-clearance application and are NOT the same population as NINo registrations. Visitor visas (2.24 million in 2025) do not lead to NINo and are excluded from the route-mix percentages so the Work / Study / Family / Other proportions are interpretable. Humanitarian routes (BN(O), Ukraine schemes, Resettlement, Asylum) are surfaced as national totals only because the same nationality split is not provided in this dataset. EU/EEA nationals largely fall outside entry-clearance for short stays, so their NINo flow is materially understated by visa data alone.

How South Cambridgeshire changed: 2011 to 2021

Two snapshots from two consecutive Censuses, ten years apart. Population changed from 148,755 in 2011 to 162,118 in 2021 (+9.0%). Non-UK-born residents went from 16,564 (11.1% of population) to 26,194 (16.2%).

Working and not working, by passport group

Census 2021 employment status of South Cambridgeshire residents aged 16 and over, by passport held. Three numbers shown per group:

  • The first three columns sum to 100% for each row. Every adult is either in work, unemployed, or inactive.
  • In work: share of all adults aged 16+ who have a paid job.
  • Unemployed: share of all adults aged 16+ who are looking for work but do not have a job.
  • Inactive: share of all adults aged 16+ who are not in the labour market. Includes retirees, full-time students, those looking after family, the long-term sick.
  • Employment rate (last column): share of those who are trying to work (excluding full-time students) who have a job. Almost always higher than In Work because it leaves out everyone who is retired, raising kids, or in full-time study.

ONS Census 2021 RM021, Economic activity status by passports held, by local authority district. NOMIS NM_2121_1. Stock measure on Census Day (21 March 2021). Passports-held is a proxy for nationality (UK = UK passport holder). Employment rate excludes full-time students from the denominator (the standard ONS definition). The 'inactive' category includes retirees, full-time students who do not work, those looking after family, long-term sick, and other reasons.

Schools, first language

Across 84 state-funded schools in South Cambridgeshire (25,808 pupils, 2024/25), 14.5% have a first language other than English. The published Cambridgeshire-wide upper-tier figure is much lower because it averages every district in the county; this is the genuine South Cambridgeshire number.

ASC sits with upper-tier authorities only (counties, unitaries, London boroughs, mets); ~153 LAs in coverage and districts are not present. Spending is shaped by demographic composition, deprivation, and informal-care availability and direct cross-area comparison must control for those.

How NHS care for overseas residents is funded (national context)

Most non-UK residents in South Cambridgeshire pay for NHS care up-front through the Immigration Health Surcharge (IHS), which is added to most visa applications. Asylum seekers, refugees, ILR holders and Irish citizens are exempt. Visitors and undocumented residents are charged at 150% of the national NHS tariff. The figures below are England + Wales national totals; per-LA NHS cost-recovery is not centrally published.

Indicative charges for visitors and undocumented residents

Maternity care is classified as "immediately necessary": it cannot be refused or delayed for charging, but it is invoiced afterwards at 150% of the NHS national tariff.

  • Routine vaginal delivery, no complications: £3,000-£5,500
  • Caesarean section: £5,000-£7,500
  • Premature birth with NICU stay: £15,000-£30,000+
  • Antenatal appointment: £150-£400 each
