Looking across a partial selection (about 100) UTLAs real consistency in the distribution of cases between admittedly quite broad age groups.
Aged 50 and over ; from the selection around 10% of cases in the most recent week; range 3.8% Tower Hamlets to 20% IoW
10 to 29s just under 60% of cases; more cases so wider range; however lowest still at 40% Slough ; highest 80% Rutland, York.
30 to 49s just under 25%; range just shy of 10% Rutland; York through to around 40%, Slough, Swindon
Which leaves the 0 to 9s at just under 8%, range 0% IoW, Rutland then York, Islington less than 2% through to 18% Derby
