Dashboard Methodology

The Muster Point Dashboard provides projected estimates of the Armed Forces veteran population across the United Kingdom between 2021 and 2035.

The dashboard combines:

  • Census 2021 veteran baseline data
  • Population projections
  • Ageing models
  • Mortality assumptions
  • Estimated Service leaver inflow modelling
  • Geographic aggregation and boundary harmonisation

The figures shown are modelled estimates designed to support:

  • Strategic planning
  • Service design
  • Community analysis
  • Comparative geographic assessment
  • Armed Forces Covenant delivery

The projections are not official ONS or MOD future veteran population forecasts.

The baseline veteran population is derived from Census 2021 responses relating to prior UK Armed Forces service.

The baseline includes:

  • Local authority geography
  • Age band
  • Sex
  • Total veteran population

This forms the starting point for all future projections.

General population projections are generated using available population datasets and projection modelling.

Population totals are projected annually from 2021 onward and aligned to:

  • Local authorities
  • Regions
  • Nations
  • Care board geographies

Projected population denominators are used to calculate:

  • Veterans per 1,000 residents
  • Working age veteran ratios

Future veteran estimates are generated using a cohort-style ageing model.

The model applies:

  • Age progression
  • Mortality assumptions
  • Estimated annual inflow of Service leavers

Veterans move through age bands annually over time.

The projection is iterative and recalculated year by year.

Estimated annual additions to the veteran population are informed using MOD Service leaver statistics.

These inflows are:

  • Applied proportionally
  • Distributed geographically
  • Modelled rather than directly observed

Local variation in veteran settlement patterns cannot currently be fully measured.

Mortality effects are applied to projected veteran cohorts over time.

The dashboard uses general cohort reduction assumptions to estimate attrition in older age groups.

These assumptions are modelled estimates and should not be interpreted as exact mortality forecasting.

Working age veteran calculations estimate the number of veterans within standard working age bands.

This allows comparison between:

  • Total veteran populations
  • Economically active age groups
  • Wider resident population projections

Data can be grouped by:

  • Local authority
  • Region
  • Nation
  • NHS Integrated Care Board
  • Welsh Health Board
  • Scottish Health Board
  • UK care board grouping

Geographic lookup tables are used to harmonise datasets across different boundary systems.

Local authority and healthcare boundaries change periodically.

Historic and modern datasets are normalised to current geographic structures where possible.

This includes:

  • Boundary code remapping
  • Name standardisation
  • Cross-dataset geographic alignment

Boundary files are sourced from official UK geographic datasets and displayed using Leaflet mapping technology.

Displayed heatmaps represent relative projected values and should be interpreted comparatively rather than as exact measurements.

Users should consider the following limitations:

  • Census 2021 remains the primary veteran baseline
  • Future veteran counts are modelled estimates
  • Local migration patterns cannot be fully measured
  • MOD inflow assumptions are national estimates
  • Mortality assumptions are simplified
  • Geographic harmonisation may introduce minor variance
  • Future ONS revisions may differ from current projections
  • Figures should support planning and analysis rather than operational decision-making in isolation
