Two independent models trained on the same Census base disagree by 2.2pp on White British share in Slough 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 Slough from 2002 to 2025, alongside the UK total for context. The peak year was 2023 (6,768 registrations). Total over the full period: 82,450 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 Slough, 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.

Home Office, Immigration system statistics, year ending March 2026 (released 21 May 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.

Police recorded crime is shaped by recording practice, reporting rates, and policing priority. Cross-area comparison must take account of those factors. Hate crime and quality-of-life detail are not in this file.

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.

DfE Special educational needs in England, academic year 2024/25 (sen_phase_type_.csv + sen_secondary_need_.csv).. EHCP responsibility sits with upper-tier authorities only, ~153 LAs in coverage. Rate-per-10k uses total LA population (Census 2021) as denominator since school-age population is not in the ethnic-projections feed; cross-LA comparison is therefore directional rather than absolute. Rising EHCP counts may reflect improved identification, changes in diagnostic criteria, increased parental awareness, or genuine prevalence change.
How NHS care for overseas residents is funded (national context)
Most non-UK residents in Slough 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.
Current IHS rate (adult, per year) £1,035
IHS rate, students/under-18s (per year) £776
IHS revenue 2024/25 (£m) £1,315.6m
Cumulative IHS revenue 2015–2024 £6.9bn
