UK GP Practice Patient Counts by Age, Sex, and Local Authority

Modelled counts of patients registered at UK General Practitioner practices, broken down by single year of age (0-95+), sex, and local authority of residence. The data is published by NHS Digital and modelled by the Greater London Authority, with patient counts available monthly and residence data quarterly. It is used as an input for modelled estimates of recent births.

Use Cases

• Tracking low-latency population trends based on patient registration data.
• Analyzing demographic distributions by age and sex at the local authority level.
• Modelling recent birth estimates based on patient register inputs.
• Investigating the impact of international migration on local population indicators.

Strengths

• Data is modelled from official NHS Digital sources, providing frequent updates with monthly and quarterly granularity.
• Breakdowns are available by single year of age, sex, and local authority of residence.
• The modelling code is publicly available on GitHub for transparency.

Limitations

• Patient counts are not a direct proxy for population and are subject to inflation, especially for areas with high international migration, adults aged 20-30, and males.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
