Trends in US live births by race and ethnicity, 2016-2024



JAMA Network Open



About The Study: 

This analysis documents a major demographic transition; non-Hispanic white births now constitute less than half of U.S. births, while Hispanic births exceed one-fourth. These shifts reflect declining fertility across most groups, contrasted with immigration trends and younger ages among Hispanic women that sustain overall birth rates.

Sex and all-cause mortality in the US, 1999 to 2019




JAMA Network Open



About The Study:

 In this cohort study of 47,000 adults participating in the National Health and Nutrition Examination Survey, after accounting for demographic characteristics (e.g., age, race and ethnicity), behavioral factors (e.g., smoking, alcohol use), and chronic conditions (e.g., diabetes, hypertension), males had a 63% greater risk of all-cause mortality than females. These findings suggest that there may be intrinsic biological factors (sex hormones, chromosomes, or immune response) associated with sex differences in mortality. Further research should investigate the effects of sex-linked biological factors on mortality.

Researchers track how the 2024 presidential election changed behaviors around firearms



A Rutgers Health study highlights an increased desire among specific groups to obtain firearms, carry them and store them more accessibly





Rutgers University




Firearm purchasing patterns can shift in response to specific events, including presidential elections, according to Rutgers Health researchers.

study by researchers with the New Jersey Gun Violence Research Center examined what extent specific groups changed their intentions and behaviors related to firearms directly in response to the 2024 presidential election by assessing a nationally representative sample of 1,530 adults in the two weeks before the election and then again in the first two weeks of 2025.

In the study, published in Injury Epidemiology, the authors found survey participants identifying as Black reported increased intentions to purchase firearms in the coming year as well as an increased desire to carry firearms because of the results of the presidential election.

Additionally, liberal beliefs were associated with greater increases in impulses to carry firearms and to store firearms in a more quickly accessible manner because of the results of the presidential election.

“These findings highlight that communities that feel directly threatened by the policies and actions of the second Trump administration are reporting a greater drive to purchase firearms, carry them outside their home, and store them in a way that allows quick access and that these urges are a direct result of the presidential election,” said Michael Anestis, executive director of the New Jersey Gun Violence Research Center at Rutgers and lead author of the study. “It may be that individuals feel that the government will not protect them or – worse yet – represents a direct threat to their safety, so they are trying to prepare themselves for self-defense.”

The authors also found survey participants  who perceive less of a threat to democracy and who view crime as a more substantial problem in the United States reported a decreased urge to carry firearms because of the results of the presidential election. Such results indicate that individuals who view the Trump administration as invested in community safety felt less of a need to be armed outside the home.

“Ultimately, it seems that groups less typically associated with firearm ownership – Black adults and those with liberal political beliefs, for instance – are feeling unsafe in the current environment and trying to find ways to protect themselves and their loved ones,” Anestis said.

“Although those beliefs are rooted in a drive for safety, firearm acquisition, carrying, and unsecure storage are all associated with the risk for suicide and unintentional injury, so I fear that the current environment is actually increasing the risk of harm,” he said. “Indeed, recent events in Minneapolis make me nervous that the environment fostered by the federal government is putting the safety of Americans in peril.” 

US Laws to keep guns away from distressed individuals reduce suicides



New research led by UC Berkeley shows that the passage of "red flag" laws meaningfully reduced the number of firearm suicides.



University of California - Berkeley



In 2023, more than half of all suicide deaths in the United States involved firearms. “Red flag” laws—also called Extreme Risk Protection Orders or ERPOs—are designed to reduce these deaths by authorizing temporary firearm removal from individuals deemed at high risk of harming themselves or others. ERPO laws had been implemented in 21 states and the District of Columbia as of February 2025. 

But the laws’ effectiveness in preventing suicides was still unclear.  

However, a new analysis led by UC Berkeley School of Public Health Research Professor of Health Policy and Management Timothy T. Brown, published today in JAMA Health Forum, shows that the passage of ERPO laws does reduce suicides by gun.

The researchers looked at data from four states that passed ERPO laws and eight that did not, and concluded that the laws reduced firearm suicides by a mean of 3.79 incidences per 100,000 population, with an estimated 675 suicides prevented across these four states between the year the law was passed and following year.  Non-firearm suicide rates did not change. “We found no evidence of individuals switching to other methods of suicide once firearms were restricted,” said Dr. Brown.

“For years, policymakers have debated whether removing firearms from individuals in crisis truly prevents suicide deaths or simply shifts people toward other methods. Our findings provide rigorous evidence that ERPO laws can prevent firearm suicides without measurable increases in suicides by other means. With only 21 states currently having these protections, there is significant opportunity for other states to adopt similar legislation and save lives," said paper co-author Yunyu Xiao, assistant professor of population health sciences at Weill Cornell Medicine. 

“I hope that policymakers will make arguments to implement this type of restriction [in other states]. It’s minimally intrusive and it definitely saves lives,” said Brown.
Co-author Mark S. Kaplan, professor emeritus of social welfare at  UCLA Luskin School of Public Affairs agrees. “Resistance often comes from gun rights organizations and conservative lawmakers, who argue that such measures threaten Second Amendment rights. It's time to prioritize community safety by adopting these vital protections,” he says.

Additional authors include Zhimeng Yan of Weill Cornell Medicine and Mark S. Kaplan of UCLA Luskin School of Public Affairs.

 

Study shows how local business benefits from city services



The impact of local tax renewals on commercial properties


University of Cincinnati





It’s common to wonder as tax season ramps up: Are taxes too high?

According to a new study by University of Cincinnati economics professor David Brasington, the answer is no, at least when it comes to Ohio’s city service taxes. These taxes go toward local services such as funds for the fire department, road repair and park upkeep. 

“It seems like public services are not over-provided at the local level in Ohio,” Brasington said. “Because good things seem to happen when people renew these taxes instead of cut them.”

Brasington, PhD, published a new study in Regional Science and Urban Economics called “Effect of local government taxes and spending on the redevelopment of commercial property.”

“What we’re doing is comparing otherwise similar communities, where some of them voted to cut taxes and services, and some voted to renew them,” he said. “And we see if there’s a difference in the amount of redevelopment of commercial property in subsequent years. And we did find a significant difference.”

The tax renewals his team looked at covered a broad range of city services, from bus drivers’ salaries to mulch for public parks. When a community votes to cut taxes, it causes a cut in these local services. 

Brasington explained that the results were straightforward. “If a community wants to preserve its commercial tax base, it’s better to renew public services,” he said, adding that the point holds true even for municipalities that are struggling financially. 

“A struggling city might be tempted to cut taxes either because of the short-term break or because people think lower taxes might draw business,” Brasington said. But the data shows the opposite: Businesses actually do better when they are in areas with good, solid public services.

“On average, if you want redevelopment in your community, it’s better to renew your local taxes,” Brasington said. He added that this goes against the preconceived notion that businesses and commercial properties have a greater chance of success when taxes are lower. 

There are a few nuances to these results. The redevelopment observed was mainly driven by service-oriented cities, not manufacturing ones. And the data only gives what Brasington calls a “glimmer of hope” to communities facing population decline, instead of hard evidence pointing toward the benefits of tax renewals. 

“For cities that are declining, the evidence is a bit more flimsy, but it at least is something that could spur some redevelopment,” Brasington said.
