Harsh Climate

The geographical area of Siberia is about 13,100,000 sq. km, which is more than the territories of the United States, China, Canada, Brazil, Australia, and India, but its total population as of January 1, 2021 is only 31,140,697 people [1]. Due to its harsh climate, many diseases, including infectious ones, have their own specific development patterns in this territory.

Elderly Suicide

Paralleling previous findings with state suicide rates of the total population, the associations of state suicide rates of elderly persons with regional IQ estimates across the USA were inconsistent (positive, negative, or nil), depending on the source of available state IQ estimates used in the analysis. The implications of these findings and directions for further inquiry are discussed.

Effective Treatments

Arthritis is a pervasive problem and over 15% of the total population of the United States has been doctor-diagnosed with arthritis. Even more Americans have symptoms. Clearly, understanding the pathogenesis of arthritis, developing effective treatments and/or finding ways to prevent it are all important goals.

Resolution Analysis

Over the past 200 years, the population of the United States grew more than 40-fold. The resulting development of the built environment has had a profound impact on the regional economic, demographic, and environmental structure of North America. Unfortunately, constraints on data availability limit opportunities to study long-term development patterns and how population growth relates to land-use change. Using hundreds of millions of property records, we undertake the finest-resolution analysis to date, in space and time, of urbanization patterns from 1810 to 2015. Temporally consistent metrics reveal distinct long-term urban development patterns characterizing processes such as settlement expansion and densification at fine granularity. Furthermore, we demonstrate that these settlement measures are robust proxies for population throughout the record and thus potential surrogates for estimating population changes at fine scales. These new insights and data vastly expand opportunities to study land use, population change, and urbanization over the past two centuries.

A large portion of the population of the United States lives in areas vulnerable to earthquake hazards. This investigation aims to quantify population and infrastructure exposure in places within the conterminous United States that are subjected to varying levels of earthquake ground motions by systematically analyzing the last four cycles of the U.S. Geological Survey's (USGS) National Seismic Hazard Models (published in 1996, 2002, 2008 and 2014). Using the 2013 LandScan data, we estimate the number of people who are exposed to potentially damaging ground motions (peak ground accelerations at or above 0.1 g). At least 28 million (~9% of the total population) may experience 0.1 g level of shaking at relatively frequent intervals [annual rate of 1 in 72 years or 50% probability of exceedance (PE) in 50 years], 57 million (~18% of the total population) may experience this level of shaking at moderately frequent intervals (annual rate of 1 in 475 years or 10% PE in 50 years), and 143 million (~46% of the total population) may experience such shaking at relatively infrequent intervals (annual rate of 1 in 2,475 years or 2% PE in 50 years). We also show that there are a significant number of critical infrastructure facilities located in high-earthquake-hazard areas (modified Mercalli intensity ≥ VII with moderately frequent recurrence interval).

Introduction: The purpose of this study was to determine how many young children and students (birth to 22 years old) were identified with visual impairments and receiving special education services in the United States. Professionals estimate at least 50% of students with visual impairments have additional disabilities and are not identified as having a visual impairments for the purposes of the federal Child Count census; therefore, the differences between Child Count and states’ total population counts were explored. Methods: A mixed-methods survey was sent to each U.S. state to determine the total population of students with visual impairments (birth to 22 years old) during the 2016–2017 school year. Results: The 49 responding states reported an average total population four times greater than the number of students with visual impairments than were documented in Child Count data. Many states had limited or no data on their total population of students with visual impairments. Discussion: The findings demonstrate many states are making policy and administrative decisions based on Child Count data not their total population data of students with visual impairments (e.g., planning for 100 students with a primary disability of visual impairments rather than a total population of 405 students with visual impairments). Misuse of Child Count data contributes to underfunding and under-hiring of teachers of students with visual impairments and orientation and mobility instructors. How to address these issues at a systemic level so all students with visual impairments receive appropriate access to resources and quality instruction is also discussed. Implications for practitioners: Practitioners can use available population data across states to educate decision makers at local and state levels regarding the differences between Child Count and total population data for students with visual impairments. Statewide vision programs can also circumvent limited data collection programs at the state level by developing their own systems for total population counts of students with visual impairments.

Hispanics are the countrys largest and fastest growing minority, but they are not an easily identified racial or ethnic group (Pew Hispanic Center, Trends 2005). In 2000, the U.S. Census reported 32.8 million Hispanics or Latinos in the United States, representing 12% of the total population. By 2004, the Hispanic population was estimated to have grown to over 40 million, an increase of more than 23% in just four years. The largest increase in the Hispanic population is occurring in the southern United States (Pew Hispanic Center). Paralleling the growth of the Hispanic population, the Hispanic labor force will expand to nearly 10 million by 2020 (Pew Hispanic Center). Language barriers and cultural sensitivities need to be addressed for optimal inclusion of this force in the U.S. The dramatic expansion of the Latino population in the State of Louisiana emphasizes the importance of this group, both socially and culturally. At the same time it presents new challenges and demands a real approach for addressing the languages barriers and the cultural sensitivities inherent in such a socioeconomic shift.

The Impact

COVID-19 has quickly spread throughout the world, infecting and killing millions of people. In an effort to contain the spread of the virus, many governments implemented stringent lockdown measures. These lockdown restrictions, coupled with social distancing, severely curtailed transportation and industrial activities, which are the primary drivers of nitrogen oxides emissions. This study investigates whether lockdown orders in the United States have impacted tropospheric nitrogen dioxide (NO2) levels by evaluating 12 major counties with a total population of 38 million. For each county, Sentinel-5P satellite data were obtained and analyzed to determine NO2 column concentrations during the pre-lockdown, peak lockdown, and loosening lockdown periods in 2020. Then, NO2 levels were compared during these three periods to the same time frame in 2019. Our results show that the lockdowns in the 12 major U.S. counties analyzed led to a significant decline in NO2 levels, with an average reduction of 28.7% (±14.6%) and 17.6% (±10.9%) during peak lockdown and loosening lockdown periods, respectively.

There are few parallels to the human holocaust that took place in Burundi in 1972 in the wake of a tortuous competitive struggle between the country’s two major ethnic groups, the Hutu and the Tutsi. Scarcely noticed (let alone understood) by public opinion anywhere, the killings are conservatively estimated to have caused between 80,000 and 100,000 deaths. Approximately 3.5 percent of the country’s total population (3.5 million) were physically wiped out in a period of a few weeks. In comparative terms this is as if England had suffered a loss of 2 million or the United States about 8 million people. To speak of “selective genocide” in describing the outcome of such large-scale political violence seems scarcely an exaggeration.
