The 31 areas of Wales where Covid is now so common one in every 100 people has it

31 areas of Wales now have Covid infection rates of more than 1,000 cases per 100,000 people.

The latest Covid data published by Public Health Wales (PHW) shows that the amount of places with more than 1,000 cases per 100,000 has increased from of those eight areas to 31 in just one week.

This data was first released on Friday, September 24. It provides the numbers for areas with an average of 7,000 people, called middle super output areas (MSOA).

In practice this means there are statistics for areas like Canton in Cardiff, Morriston in Swansea, and Porth in Rhondda.

The data shows there are 31 places in Wales with more than 1,000 cases per 100,000 of population and 43 where the figure exceeds 900.

At the other end of the spectrum, WalesOnline has reported each week all of the areas of Wales that have fewer than three Covid cases. For a over six weeks now every single part of Wales has more than two cases of coronavirus reflecting how widespread the virus is at the present time.

It is important to bear in mind that this data is very volatile because it covers smaller areas. Where an area has a very small population even one positive case can push up the cases per 100,000 significantly. You should therefore be cautious about drawing too many conclusions directly from the information.
