Neighborhood Poverty: The percent of a ZIP code's population living below the Federal Poverty Level, based on the 2014-2018 American Community Survey.
Percent Positive: Among people who were tested, the percent of people who tested positive.
Rate per 100,000 People: Rates are numbers that are adjusted for population (similar to per capita). They help us compare areas with different population sizes.
For example, if one neighborhood has 1,500 COVID-19 cases out of 25,000 people, and another neighborhood has 2,000 cases among 30,000 people, converting these to rates (6,000 per 100,000 people; 6,660 per 100,000 people) lets us compare how COVID-19 is affecting these two neighborhoods.
We use rates to compare numbers of cases, hospitalizations, and testing, among other measures.
Testing Types: See our COVID-19: Testing page.
Variant Classifications: The CDC classifies some variants as:

Doses Administered: The total doses that have been given to residents and non-residents in NYC. This includes the two-dose Moderna or Pfizer primary vaccine series, the one-dose Johnson & Johnson primary vaccine series, two dose Novavax vaccine series, additional doses of Moderna, Pfizer or Johnson & Johnson, and bivalent doses of Moderna and Pfizer.
Estimating Doses from Records: Due to possible inconsistencies in the vaccine records of separate doses administered to the same person, our numbers may overestimate the number of people who have received at least one dose and underestimate those who have received more than one dose.
Vaccinations Data Source: Data on COVID-19 vaccines comes from the Citywide Immunization Registry, which collects immunization records for children aged 0 to 18 years and — with their consent — adults aged 19 and older. All administered COVID-19 vaccine doses must be reported to the Registry.
Vaccination Status: The number of NYC residents vaccinated at an NYC facility, as well as city residents who were vaccinated outside of NYC and reported to us by: a provider in the city; the New York State Immunization Information System; the New Jersey Immunization Information System; or the Connecticut Immunization Registry and Tracking System.
Vaccination status is classified into the following categories:
Confirmed Case: A case is classified as confirmed after a positive result from a molecular test, such as a PCR test.
Confirmed Death: A confirmed death is a death that followed a positive molecular test and was not related to external causes, such as a gunshot wound or drug overdose.
Probable Case: A case is classified as probable after any of the following:
Probable Death: A probable death is when the cause of death on the death certificate is COVID-19 or similar, but a positive molecular test is not on record.

About Health Inequities in Data: Differences in health outcomes and vaccination coverage among racial and ethnic groups are due to long-term structural racism, not biological or personal traits.
