NYC Neighborhood Covid-19 DASHBOARD

The NYC Neighborhoods COVID-19 Dashboard is a tracker and data visualization tool to provide continuously updated sources of COVID-19 data in NYC for lay public, essential workers, policymakers, and researchers.
There are four tools available (located at the top navigation menu):

  • COVID-19 Tracker provides daily tracking of the local development for COVID-19 cases, deaths, and tests in 177 NYC ZIP Code Tabulation Areas (ZCTAs).
  • COVID-19 Distribution provides a data visualization of COVID-19 cases, hospitalizations, and deaths in NYC ZCTAs and by age, gender, and race/ethnicity.
  • COVID-19 Trends shows the time trends for COVID-19 cases, hospitalizations, and deaths by NYC boroughs, ZCTAs, and demographics.
  • Neighborhoods shows and compares the neighborhood characteristics of NYC ZCTAs.


In early April, at one of his popular daily briefings, Governor Andrew Cuomo began by quipping that all the days seem to blend together before launching into a presentation on the rapid spread of COVID-19. He explained what the science was saying about the potential for hospitals to be overwhelmed—evidence supporting the necessity of a lockdown. Among the science he cited were “frightening” projections by Columbia Mailman Professor Jeffrey Shaman’s research group, noting “that’s the one that keeps me up at night.”

Nov. 05 2020, Doctoral Student’s COVID-19 Testing Disparities Research Makes Headlines

Research by Wil Lieberman-Cribbin, a doctoral student in environmental health sciences, is revealing neighborhood disparities in coronavirus testing in New York City. As any public health student knows, testing is the cornerstone of disease surveillance, and never more so than during a pandemic. Absent a clear picture of where COVID-19 is spreading, public health officials are less able to orchestrate an effective response. Lieberman-Cribbin’s research was the focus of an October 30 New York Times article, which summarized his findings:

“Overwhelmingly, the wealthiest neighborhoods—in fact, most of Manhattan below 110th Street—showed the highest rates of testing, while the poorest neighborhoods, in Central Brooklyn and the South Bronx, for example, largely correlated with the lowest. In some instances, the differences between the most affluent communities and the least advantaged were four times as great.”

Oct. 14 2020 Will the COVID-19 Virus Become Endemic?

 A new article by Columbia Mailman School researchers Jeffrey Shaman and Marta Galanti explores the potential for the COVID-19 virus to become endemic, a regular feature producing recurring outbreaks in humans. They identify crucial contributing factors, including the risk for reinfection, vaccine availability and efficacy, as well as potential seasonality and interactions with other viral infections that may modulate the transmission of the virus. The article appears in the journal Science.

September 29, 2020 Epidemiology Professor Offers Clarity in a Confusing Time

As we’ve seen repeatedly over the last six months, public health measures to fight the pandemic are contingent on the cooperation of the public. People wear masks only so long as they have the correct information and trust those providing guidance. Sadly, in the United States, too often we’ve been given mixed messages and misinformation.

September 23, 2020 Expert Panel Assesses Animal Models for COVID-19 Research

Angela Rasmussen, a virologist and associate research scientist in the Center for Infection and Immunity at Columbia University Mailman School of Public Health, is a member of an international panel assembled by the World Health Organization (WHO) to develop animal models for COVID-19 to accelerate the testing of vaccines and therapeutic agents.

September 17, 2020 Study Identifies Innovative Responses to Pandemic School Meal Program Disruption

Researchers estimate more than 1 billion school meals were not served in school as a result of school closures prior to May 1.

School closures due to the COVID-19 pandemic disrupted access to low or no-cost school breakfast and lunch programs for millions of low-income children. States and school districts developed innovative solutions to meet the nutritional needs of children and respond to the rapidly growing food insecurity crisis, yet the number of replacement meals is likely far short of what they provided prior to the pandemic, according to a study led by a researcher at Columbia University Mailman School of Public Health. The findings are published in the American Journal of Public Health.

September 14, 2020 Lockdown Led to 70% Drop in NYC COVID Spread, Masks Also Effective

Reducing contact rates—mainly via school closures and voluntary or mandated stay-at-home measures—contributed to around a 70 percent reduction in the transmission of COVID-19 in New York City during the spring pandemic wave from March to the June reopening. Widespread use of face coverings contributed an additional 7 percent reduction, and up to 20 percent reduction among those aged 65 and older during the first month face covering was mandated in public places.

September 9, 2020 COVID Dashboard Tracks Pandemic in New York City

Thanks to effective public health measures, the COVID-19 outbreak is now much less severe in New York City than it was in the spring, although upwards of 100 people still test positive every day. As businesses and schools reopen, there is a chance that the coronavirus could reassert itself.

September 4, 2020 What one pandemic can teach us in facing another

Almost exactly 39 years ago, the US Centers for Disease Control reported five cases of Pneumocystis carinii pneumonia among previously healthy gay men [1]. By the end of 1985, HIV was reported from every region in the world. Three decades later, 75 million people have acquired HIV and about 32 million have died from it [2].

August 31, 2020 School Hosts COVID-19 Course to Highlight Latest Science on the Pandemic

The COVID-19 pandemic has reshaped our lives in ways previously unimaginable, wreaking havoc in communities near and far.

August 27, 2020 ICAP’s Global COVID-19 Response Is Improving the Odds for Millions of People in Vulnerable Communities Around the World

“When COVID-19 emerged, we realized that we had to pivot to quickly mobilize the resources needed in order to respond to the urgent calls for assistance that we were receiving.”  — Wafaa El-Sadr, ICAP Director

Since the first evidence of the coronavirus pandemic earlier this year, ICAP at Columbia University recognized the potentially devastating impact of COVID-19 in many of the countries where it works, countries where health systems are particularly fragile. Building on nearly two decades of experience in responding to the world’s most significant public health challenges and harnessing its longstanding partnerships with ministries of health across the globe, ICAP has mounted a comprehensive response to COVID-19 in 24 countries in Africa, Asia, and the Americas in partnership with stakeholders in each of the countries.

July 22, 2020 What We Know and Still Don’t Know About COVID-19

The world has been living through the COVID-19 pandemic for nearly eight months. Much is still unknown about the illness that has stricken 14.8 million people and killed more than 610,000 worldwide, but every day brings new insights and developments. Columbia experts have been at the forefront of the international response to this crisis. We asked them to review what we’ve learned, so far, and to discuss the most significant challenges ahead.

July 13, 2020 Researchers Issue Call to Action to Strengthen Pandemic Behavioral Science

Although information about COVID-19 protective behaviors such as handwashing, mask-wearing, and social distancing has been widely disseminated in the United States by federal and local governments, research has shown significant gaps in the public’s understanding and behavior, maybe because of inconsistency and lack of optimal tailoring. A new article in the American Journal of Preventive Medicine led by Columbia research John Allegrante, PhD, argues behavioral science expertise that is central to achieving protective behaviors. 

July 06, 2020 Policy Recommendations to Prepare for the Second Wave of COVID-19

As COVID-19 continues to spread, countries around the world are working to establish public health policies that balance re-opening their economies with mitigating the spread of infection, to varying degrees of success. Several months into the global pandemic, the United States faces a new surge of cases, and possibly a second wave.

July 01, 2020 COVID-19 Fatality Risk Is Double Earlier Estimates: Study

The new estimates are based on robust New York City data and underline the importance of infection prevention, particularly among older adults whose risk is significantly elevated.

In one of the most robust studies of COVID-19 mortality risk in the United States, researchers estimate an infection fatality rate more than double estimates from other countries, with the greatest risk to older adults. Columbia University Mailman School of Public Health scientists and New York City Department of Health and Mental Hygiene colleagues published the findings on the pre-print server medRxiv ahead of peer review.

July 01, 2020 Study Examines Limiting School Capacity for New York City Reopening

Data modeling projections by Columbia University Mailman School of Public Health scientists evaluate potential policies to reduce new infections, hospitalizations, and deaths in coming months, including by limiting school capacity by 50 percent or capping capacity of certain industries to 25 percent during Phase Four, as well as by implementing an “adaptive PAUSE” system to re-implement social distancing rules during a rebound. The researchers have been working with the New York City Department of Health and Mental Hygiene on COVID-19 planning. Their new report is posted on Github.

June 18, 2020 COVID-19 Affects Adolescent and Young Adults Sexual and Reproductive Health

Social distancing and limited access to contraceptive and abortion care during the COVID-19 pandemic is affecting the sexual and reproductive health of adolescents and young adults according to a new study by researchers at Columbia University Mailman School of Public Health and Rutgers University. The researchers address how these challenges, as well as peer and romantic relationships, are being navigated. The findings are published in the journal Perspectives in Sexual and Reproductive Health.

June 17, 2020 Data Dashboard Highlights COVID-19 Demographics and Time Trends

As news reports underline the disproportionate toll of COVID-19 on racial and ethnic minorities in the United States, a new data visualization dashboard developed by Columbia University Mailman School of Public Health scientists may be the first to compile state-level COVID-19 demographic information for age, race/ethnicity and sex. The Demographics by State COVID-19 Reporting (DSCovR) Dashboard allows policymakers, scientists, and the lay public to visualize and compare COVID-19 time trends and demographic information among cases, hospitalizations, and deaths across states.

Jun. 05 2020 NYC Subway Data Reveals Communities of Color Carry the Burden of Essential Work and COVID-19

A new study shows there was substantial social distancing inequalities throughout New York City during the COVID-19 pandemic. Researchers at Columbia University Mailman School of Public Health and Boston University School of Public Health reported that areas with the lowest individual income and a greater percentage of non-white and/or Hispanic/Latino individuals, used the subway to a greater degree during the pandemic, and the strongest driver of subway use in communities of color was the percent of individuals in essential work. This is one of the first studies to assess the interrelationship between sociodemographic factors, mobility, and COVID-19. Findings are online in the preprint of medRxiv ahead of peer-reviewed publication.

May 15, 2020 Context is Crucial in Discussion of COVID Disparities

As news reports highlight the devastating impact of COVID-19 in communities of color, including elevated rates of severe illness and death, Columbia Mailman School experts say more attention should be paid to factors that give rise to those outcomes.

May 15, 2020 A Foot in Two Worlds: A View of Coronavirus from the South Bronx

Early research has revealed that people of color, and those living in poverty and crowded housing situations have been disproportionately affected by COVID-19. But these findings have come as no surprise to Diana Hernández, who grew up in the South Bronx and is still a resident of the diverse and historically low-income New York City neighborhood, which is a hotspot for the virus. 

May 11, 2020 Up to 5 NY Children Dead, 93 Sickened by Rare COVID-Related Illness

May 04 2020 Breaking the Silence: Domestic Violence During COVID-19

Rates of domestic violence that are already shockingly high—one in four women and one in ten men in the U.S. experience intimate partner violence—could be even higher today as a consequence of the COVID-19 pandemic. This month in New York City, calls to domestic violence hotlines and visits to support websites in New York City have spiked. A newly published paper by Columbia University Mailman School of Public Health researchers cites reports of a recent surge in domestic violence in China during the COVID-19 pandemic.

April 27,2020 When It Comes to Coronavirus Deaths, Race Matters

Instead of affecting everyone equally, the coronavirus is amplifying the racial disparities in health outcomes across the United States. The disparities result from the country’s own pre-existing condition: an environment where people’s living and working conditions are anything but equal when it comes to pollution levels and protection from harmful toxins.

April 20, 2020 11 Numbers That Show How Coronavirus Has Changed N.Y.C.

But some of the data shows glimmers of hope. While hundreds of food banks were forced to close, the city’s volunteer pool vastly expanded. Air pollution is down. Applications to foster abandoned animals skyrocketed.

April 17, 2020 When a Virus Exposes Environmental Injustice

 A map recently released by the city’s Department of Health and Mental Hygiene broke down confirmed cases by ZIP code, and the results are shockingly clear: The coronavirus is disproportionately affecting low-income neighborhoods, which in New York also tend to be communities of color.
