Coronavirus as Recorded in Primary Care - EXPERIMENTAL STATISTICS

4. Demographic Groupings

Several patient demographics were examined, including sex, age, socio-economic status and ethnicity.

4.1 Region

Geographic region is determined from the patient’s LSOA, derived from the postcode in the source dataset.

4.2 Deprivation

Deprivation is inferred using the English Index of Multiple Deprivation (IMD). The Ministry of Housing, Communities and Local Government (MHCLG) calculates these figures using mid-2019 estimates for each LSOA. The values are assigned to patients in this analysis based on their LSOA. Each area is ranked from most to least deprived and then are divided into five equal groups (quintiles). The first quintile represents the 20% most deprived and the fifth the 20% least deprived LSOAs in England.

4.3 Ethnic group

In the analysis nine ethnic groups were considered, as described in Table 3. The nine groups correspond to those used in (White & Ayoubkhani, 2020), an Office for National Statistics (ONS) report which discusses differences in death rates from coronavirus by ethnicity.

4.4 Age

Age is calculated at event date. Patients are grouped into age bands of roughly similar lifestyle patterns: pre-school, primary school, and secondary school children, young adults possibly in higher education, adults, and elderly. The age bands are as follows:

  • 0-4
  • 5-11
  • 12-17
  • 18-25
  • 26-34
  • 35-49 
  • 50-69 
  • 70-79 
  • 80-89 
  • 90+
