  1. a Only the top 10 areas based on the frequency of the number of times with > = 80% probability of being among the top 10 areas with high swab positivity are presented.
  2. b Deprivation was measured using the 2019 English index of multiple deprivation at a smaller geographical level than CIS areas. The average deprivation score rank ranges from 1 (most deprived CIS area) to 116 (least deprived CIS area), estimated by ranking CIS areas based on the population-weighted average deprivation score of people living in different smaller areas – with each their deprivation score - within CIS areas.
  3. c This percentage is based on first identifying the 10% most deprived areas in England as a whole based on the 2019 English index of multiple deprivation, and subsequently estimating the percentage of the total population in each CIS area that lives in those 10% most deprived areas in England.
