Community level (MSOAs) COVID-19 new cases per 100,000 by week and percentage of positive school samples.
Note: Each box shows the distribution of new cases per 100,000 across the community (MSOA*) of each school and all the adjacent communities for a total of 92 MSOAs). Solid lines show medians; the boxes show Interquartile Ranges; the whiskers show ranges. Dashed lines indicate the percentage of weekly positive samples (weeks in this figure are defined based on the MSOA data availability and may differ from the weeks of the study). * MSOAs (Middle Layer Super Output Areas) are a geographic hierarchy designed to improve the reporting of small area statistics in England and Wales.
