Cohort-component 77.8% Births by ethnicity-specific total fertility rate (TFR) with half-convergence to the national mean by 2061. Slower change.
Two independent models trained on the same Census base disagree by 0.0pp on White British share in Monmouthshire 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.

Arrivals over the last 24 years
Annual NINo registrations to adults from overseas in Monmouthshire from 2002 to 2025, alongside the UK total for context. The peak year was 2022 (437 registrations). Total over the full period: 2,635 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.
