For two years, Centre for Cities updated this tracker with the latest data from Public Health England — and mapped this at the Primary Urban Area (PUA) level for England.

Where in England had the highest number of new Coronavirus cases at the end of March 2022?

The final update of this tracker happened on 23 March 2022.

This Covid-19 case tracker aggregated the local authority data on Covid-19 cases reported daily to Public Health England, at the Primary Urban Area (PUA) level for England. To explore wider economic data on your city or large town, explore City Monitor.

Notes

This Covid-19 case tracker aggregates the local authority data on Covid-19 cases reported daily to Public Health England, at the Primary Urban Area (PUA) level for England.

For all the 55 largest cities and towns in England, it summarises the latest development on Covid-19 spread, by looking at the sum of newly-reported cases over the past week, and comparing it to the four previous weeks. This will allow to identify the most recent spikes in cases, and how they evolve over time.

In order to visualise how cities have been affected since the pandemic began, data on the cumulative number of cases is also provided.

In order to control for population size, the data presented here is given per 100,000 population.

Confirmed cases here refer to cases reported positive to Public Health England, from Pillar 1 and Pillar 2 testing. Duplicate tests for the same person are removed.

The rates may be affected by geographic variation in testing. Local data on testing would help address this bias, but is currently not available at the local level. This tracker will be updated weekly.

This data aggregates the local authority (UTLA) data reported daily to Public Health England, at the Primary Urban Area (PUA) level for England. This graph does not provide data for all PUAs as only upper-tier local authorities whose geography could directly be matched to PUA geography have been considered in the analysis.

It does not take into account the number of Covid-19 cases which have not been attributed to any local authority- hence potential differences with the total number of cases in England.

It should be acknowledged that this data might not represent the place of residence of confirmed cases, but in some cases the location of the hospital which reported the data, where the patient has been tested. The data provided here is therefore likely to be an underestimate of the total number of cases in an area, as only confirmed cases (tested positive) are recorded.

The rates may be affected by geographical variation in testing. Local data on testing would help  address this bias, but it is not currently available at the local authority level in England.
