China’s population decline, announced today. will continue to accelerate given the nation’s fertility and mortality trends, according to Johns Hopkins University sociologist Feinian Chen, who has extensively studied China’s aging population and health. “China’s recently adjusted three-child policy did little to boost…
Unlike turkeys headed for Thanksgiving tables, wild ones are vanishing as a WVU researcher hunts for clues
Wild turkey populations are disappearing in many states and a West Virginia University researcher is working to find out why.
Artificial intelligence answers the call for quail information
When states want to gauge quail populations, the process can be grueling, time-consuming and expensive. It means spending hours in the field listening for calls. Or leaving a recording device in the field to catch what sounds are made—only to spend hours later listening to that audio. Then, repeating this process until there’s enough information to start making population estimates.
But a new model developed by researchers at the University of Georgia aims to streamline this process. By using artificial intelligence to analyze terabytes of recordings for quail calls, the process gives wildlife managers the ability to gather the data they need in a matter of minutes.
Stress from rising population numbers may cause a decline in human fertility
A predicted population drop at the end of the century could be explained by stress from meaningless social interactions, according to a review article published in the Endocrine Society’s journal, Endocrinology.
Indiana’s Census 2020 results: Metro areas and minority populations fuel state’s growth
Latest results from the 2020 Census show that Indiana’s population growth over the past decade largely was driven by gains in a handful of metropolitan areas and exclusively through gains among the state’s minority populations, according to analysis by the Indiana Business Research Center at Indiana University’s Kelley School of Business.
Assessing the impacts of global climate change on population trends
The European Research Council (ERC) will fund groundbreaking research led by IIASA World Population Program Deputy Director Raya Muttarak, which will comprehensively address the impacts of climate change on population dynamics.

How birth control, girls’ education can slow population growth
Education and family planning have long been tied to lower fertility trends. But new research from the University of Washington analyzes those factors to determine, what accelerates a decline in otherwise high-fertility countries.
Utah’s young population contributes to relatively low COVID-19 death rate
Research from the Kem C. Gardner Policy Institute shows Utah’s relatively young population is contributing to a lower COVID-19 death rate than the nation as a whole.
Community science birding data does not yet capture global bird trends
Ornithologists at the University of Utah say that community science bird data shows different trends in bird populations than professional bird surveys do, especially in developing countries. More observations are needed, the researchers say, both by birders and professionals.

A New Way to Accurately Estimate COVID-19 Death Toll
A Rutgers engineer has created a mathematical model that accurately estimates the death toll linked to the COVID-19 pandemic in the United States and could be used around the world. The model, detailed in a study published in the journal Mathematics, predicted the death toll would eventually reach about 68,120 in the United States as a result of the SARS-CoV-2 coronavirus that causes COVID-19. That’s based on data available on April 28, and there was high confidence (99 percent) the expected death toll would be between 66,055 and 70,304.
Rethinking mortality and how we plan for old age
Many people dream of comfortably living out their golden years. A new IIASA study however shows that older Europeans, and especially women, frequently underestimate how many years they have left, which could lead to costly decisions related to planning for their remaining life course.
Annual Survey Shows Indian Foreign-Born Population Is the Largest in St. Louis Region
Results of a new Saint Louis University survey showed that the Indian foreign-born population is the largest foreign-born population in the St. Louis region.
UIC report examines black population loss in Chicago
A mix of factors is involved in Chicago’s declining black population and others aren’t well defined, but inequality stands out as a leading element, according to a new report from the Institute for Research on Race and Public Policy at the University of Illinois at Chicago.
New Portable Tool Analyzes Microbes in the Environment
Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.
