Reducing Late-Night Alcohol Sales Curbed All Violent Crimes by 23% Annually in a Baltimore Neighborhood

A new study found that reducing alcohol hours of sale for bars and taverns in a Baltimore, Md. neighborhood also reduced homicides by 51 percent within the first month and by 40 percent annually, pointing to possible opportunities for other cities to address excessive drinking and crime.

Simply reducing the hours during which alcohol may be purchased can significantly reduce violent crime, according to a new study led by Boston University School of Public Health (BUSPH) and the Alcohol Research Group of Emeryville, Calif. The findings were published in JAMA Internal Medicine on Monday, April 1.

Substantial research has linked alcohol sales at liquor stores and other establishments to increased neighborhood crime, but this is the first study to look at the impact of changing the hours of sale in a low-income neighborhood on crime in that neighborhood.

The study found that shortening overnight operations by seven hours at bars and taverns in a Baltimore, Md. neighborhood resulted in a 51 percent immediate drop in homicides within the first month, followed by a 23 percent decline in all violent crimes annually in the surrounding area, compared to similar neighborhoods with no change in hours of sale. Homicide rates decreased by 40 percent in each subsequent year.

“We were able to take advantage of this natural experiment, and apply rigorous analytic methods to assess the effect of the change,” says study lead author Dr. Erika Rosen of the Alcohol Research Group. “While we expected to see some change, the size of the drop in crime was even more significant than we expected.”

The research team evaluated the impact of the Maryland Senate Bill 571 (SB571) passed by the state legislature in 2020. The bill reduced the hours of sale for alcohol in 2020, from 20 hours per day to 13 hours per day (from 6 a.m. to 2 am, to 9 a.m. to 10 p.m.).Their analysis also estimated that this reduction in crime saved the City of Baltimore an estimated $18.2 million in annual costs.

These findings suggest that reducing late-night hours of sale may be an effective way for cities to curb excessive drinking—a persistent problem that worsened nationwide during the COVID-19 pandemic—as well as homicides, assaults, and other crimes.

The study team utilized publicly available data to measure total violent crime incidents within 800 feet of bars and taverns in a Baltimore neighborhood from May 2018 to December 2022—before and after the new legislation on hours of operation was implemented in September 2020. The team focused on total late-night crime occurrences between 8 p.m. and 4 a.m. around 26 bars and taverns, because these are the times at which crime is most likely to be associated with alcohol use. Then they compared these crimes to crimes happening near 41 other bars and taverns with unchanged hours of operation in demographically similar Baltimore neighborhoods.

The study assessed both violent crime—defined as homicide, robbery, aggravated assault, and forcible rape—and common assault, adjusting for neighborhood factors such as population size, percentage of Black and White residents, alcohol outlet totals per square mile, neighborhood disadvantage, and number of convenience stores.

Notably, the researchers also conducted additional sensitivity analyses that confirmed the decline of late-night crimes, suggesting that crimes did not shift to earlier hours of the day or to adjacent neighborhoods.

“Changing the hours of service and sale of alcohol is a relatively simple intervention,” said study co-author Dr. David Jernigan, professor of health law, policy & management at BUSPH. “Yet our findings suggest that, even in a period like the COVID-19 pandemic when alcohol consumption was rising, this policy has great promise for other cities and neighborhoods seeking to prevent and reduce crime.” 

Additional research is needed to test this policy in other cities and for longer periods of time, but the researchers hope this evaluation serves as a potential model for other cities to consider implementing to decrease crime in their neighborhoods and support residents’ overall health and safety.

“Our study provides new and compelling evidence that supports the World Health Organization’s three “best buys” to reduce alcohol attributable morbidity and mortality through reducing availability of alcoholic beverages, along with increasing prices via taxation and banning alcohol marketing,” says study senior author Dr. Ziming Xuan, professor of community health sciences “These findings highlight the critical importance of population-based alcohol policies in violence prevention.”

Funding for the study was provided by a pilot research grant from BUSPH, the National Institute on Alcohol Abuse and Alcoholism, and the Centers for Disease Control and Prevention.

Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it.  But by improving on a well-known electrochemical reaction and orchestrating a “symphony” of lithium, nitrogen and hydrogen atoms, University of Illinois Chicago engineers led by Meenesh Singh have developed a new ammonia production processthat meets several green targets.  The process, called ...

Old crystal, new story for enhancing deep ultraviolet laser performance
2024-04-01
In the realm of science and technology, harnessing coherent light sources in the deep ultraviolet (DUV) region holds immense significance across various applications such as lithography, defect inspection, metrology, and spectroscopy. Traditionally, high-power 193-nanometer (nm) lasers have been pivotal in lithography, forming an integral part of systems used for precise patterning. However, the coherence limitations associated with conventional ArF excimer lasers hinder their effectiveness in applications requiring high-resolution patterns, like interference lithography. Enter the concept of the "hybrid ArF excimer laser." ...

Ancient Adélie penguin DNA reveals that small repeats persist for hundreds of millions of years
2024-04-01
Microsatellites are valuable tools for studying inheritance, genetic diversity, and population dynamics across a wide range of organisms including bacteria, plants, animals, and fungi. These short, repeating sequence motifs are a common feature of both coding and non-coding DNA and have been observed in all genomes studied to date. Their repetitive nature leads to “slippage” in the DNA replication machinery, resulting in the addition or subtraction of repeats that causes microsatellites to grow or shrink in length. Because of this, there is considerable variability ...
