I put this on another thread but it probably should belong in the analysis thread so re-posting here. Credit to @PatriciaHolm again for the original map link.
@PatriciaHolm posted these PHE maps on another thread from their most recent weekly surveillance report (so published last week). Just the weekly case one added here
Whereas the daily dashboard publishes pillar 1 in terms of both actual confirmed cases and confirmed cases per 100,000 people the PHE maps just give a banding of cases per 100,000 residents. The maps are also upper tier local authorities only, and you do need to know your local authority geography. councils' map www.google.com/maps/d/u/0/viewer?hl=en&mid=1S_AbfmYbOpHBeyLEcmB9f-wRD4Y&ll=53.59615067528699%2C-2.0960400430810333&z=10
Not quite sure how the maps display, but one shows the cumulative position for pillar 1 and pillar 2; and the other for the most recent week.
If which map is which is not apparent on the cumulative map the red areas have over 601 cases per 100,000 and on the weekly one red is over 45 cases per 100,000
The weekly map might be of greater interest. So red and dark red blobs include Bedford, moving into the Midlands to Leicester; up into South Yorkshire which looks to be Rotherham; then up to Barnsley (dark red); Kirklees (red) and Bradford (dark red - this presumably explains why Keighley has been mentioned as a surge area). Then west to Oldham, Tameside, and Rochdale (dark red) and finally Blackburn.
The banding is a bit of a blunt instrument. County Council areas are a bit meaningless. Kent has a population not far off 1.6m people, and 12 district councils areas, which probably don't all have the same case rate. So just cumulative pillar 1 from the dashboard has Ashford at over 700 cases per 100,000 whereas Tonbridge and Malling has less than 200 per 100,000.
Likewise there is no way of knowing on the maps if an LA is near the bottom or top of a banding. So Cheshire West is in the 10 to 15 per 100,000 band and Cheshire East the 15 to 30 band. The former might be 10 and the latter 29.9, so a significant difference; ot it could be West in 14.9 and East 15.1 so to all intents and purposes the same.
