New Jersey Overview
When New Jersey reports no data, several days of data, or unusual data (such as decreases in values that should increase), our volunteers note it here on the date the anomaly occurred. We also note here changes in our own methodology that affect the data.
The Recovered data point we report for New Jersey reflects the number of COVID-19 patients discharged from the hospital and therefore does not represent the total number of people who have recovered from COVID-19, since many people with COVID are never hospitalized.
Negative test results reported in our API and CSVs are calculated by subtracting Confirmed cases from Total PCR tests (specimens).
On January 15, 2021, New Jersey’s Probable cases decreased from 59,881 to 31,717 on their data dashboard without explanation. We believe this decrease may have been a mistake and sourced this data point from the underlying data layer (today's value is 60,791) in order to avoid the decrease.
On January 8, 2021 New Jersey’s Probable cases increased from 53,967 to 72,123 without explanation. This affected their Cases (confirmed + probable), which is calculated as Confirmed cases plus Probable cases in the absence of an explicit total case number. On January 9, 2021, their Probable cases decreased from 72,123 to 56,147. Because of this, we believe that the figure reported on January 8, 2021 was a mistake, and are correcting the number in our timeseries.
On October 23, New Jersey's reported Ever hospitalized value increased dramatically from 24,517 to 37,222 with no explanation we could find: this was probably a one-time addition of backlogged data.
On September 1, New Jersey did not update their total PCR test figure by the time of our update, however total cases increased from 191,160 to 192,290.
On August 7, 2020, we back-filled New Jersey's Probable deaths with data provided by the state. This removed apparent spikes in deaths due to the state's irregular reporting.
On August 4, 2020, New Jersey's Now hospitalized number decreased by 268 people.
On July 19, 2020, New Jersey's Total cases decreased, perhaps due to reclassification of probable cases.
On July 16, 2020, New Jersey's Recovered figure decreased.
On May 16, 2020, a backfill effort by New Jersey caused the state's data for Recovered to rise by approximately 7,000 people.
