“Postal code data provides not only a map of where New Yorkers are being vaccinated, but also a roadmap for our Covid response,” said Easterling.
Also on Tuesday, Governor Andrew M. Cuomo released data showing that white people are being vaccinated at a higher than expected rate based on their eligible population in all regions of the state. But blacks were being vaccinated at about half the rate expected in most regions.
In New York City, for example, 58% of those vaccinated were white, while whites made up only 52% of the eligible population, according to state data. About 14.4 percent of those vaccinated were black, although blacks made up more than 30 percent of the eligible population.
About 16 percent of those vaccinated in the city were Hispanic or Latino, but Hispanics or Latinos make up about 24 percent of the eligible population, according to state data.
Experts say people across the country who live in poor neighborhoods face a variety of obstacles to vaccination, including registration systems and websites that can take hours to navigate, lack of transportation and difficulty taking time off work to take a vaccine. Many people in communities of color are more likely to hesitate to be vaccinated, in light of the history of unethical medical research in the United States.
Mr. de Blasio said on Tuesday that a new vaccination site would open on Wednesday at the Teachers’ Preparatory High School in Brownsville, Brooklyn, and would open six days a week and would give priority to home health workers and people living in Brownsville and East New York.
“It is about addressing inequality, doing something very tangible about it,” he said.
Another new vaccine site will open on Thursday at the Empire Outlets on Staten Island, he said.
The city vaccinated 317,227 people last week, including 55,339 people in one day, said de Blasio, adding that more than 10 percent of New Yorkers have already received at least one dose. He said the city could vaccinate many more people each day if it got more doses from the federal government.
