“The ZIP code data not only provides a map of where New Yorkers are being vaccinated, but also a road map to our Covid response,” Dr. Easterling said.
Also on Tuesday, Gov. Andrew M. Cuomo released data that showed white people were being vaccinated at a higher rate than expected based on their eligible population in every region statewide. But Black people were being vaccinated at about half the expected rate in most regions.
In New York City, for example, 58 percent of those vaccinated were white, while white people made up only 52 percent of the eligible population, according to the state data. About 14.4 percent of those vaccinated were Black, despite Black people comprising more than 30 percent of the eligible population.
About 16 percent of those vaccinated in the city were Hispanic or Latino, but Hispanic or Latino people make up about 24 percent of the eligible population, according to the state data.
Experts say people across the country who live in underserved neighborhoods face a variety of obstacles to vaccination, including registration systems and websites that can take hours to navigate, a lack of transportation and difficulty getting time off from work to get a shot. Many people in communities of color are more likely to be hesitant about getting vaccinated, in light of the history of unethical medical research in the United States.
Mr. de Blasio said on Tuesday that a new vaccine site was opening on Wednesday at the Teachers Preparatory High School in Brownsville, Brooklyn, and would be open six days a week and give priority to home health aides and to people living in Brownsville and East New York.
“This is about addressing inequality, doing something very tangible about it,” he said.
Another new vaccine site would open on Thursday at the Empire Outlets in Staten Island, he said.
The city vaccinated 317,227 people last week, including 55,339 people on one day, Mr. de Blasio said, adding that more than 10 percent of New Yorkers had now received at least one dose. He said the city could vaccinate far more people each day if it could get more doses from the federal government.
