Rapid population growth in developing countries in the middle of the 20th century led to fears of a population explosion and motivated the inception of what effectively became a global population-control program. The initiative, propelled in its beginnings by intellectual elites in the United States, Sweden, and some developing countries, mobilized resources to enact policies aimed at reducing fertility by widening contraception provision and changing family-size norms. In the following five decades, fertility rates fell dramatically, with a majority of countries converging to a fertility rate just above two children per woman, despite large cross-country differences in economic variables such as GDP per capita, education levels, urbanization, and female labor force participation. The fast decline in fertility rates in developing economies stands in sharp contrast with the gradual decline experienced earlier by more mature economies. In this paper, we argue that population-control policies likely played a central role in the global decline in fertility rates in recent decades and can explain some patterns of that fertility decline that are not well accounted for by other socioeconomic factors.
The graph shows the population growth in China from 2000 to 2024. In 2024, the Chinese population decreased by about 0.1 percent or 1.39 million to around 1.408 billion people. Declining population growth in China Due to strict birth control measures by the Chinese government as well as changing family and work situations of the Chinese people, population growth has subsided over the past decades. Although the gradual abolition of the one-child policy from 2014 on led to temporarily higher birth figures, growth rates further decreased in recent years. As of 2024, leading countries in population growth could almost exclusively be found on the African continent and the Arabian Peninsula. Nevertheless, as of mid 2024, Asia ranked first by a wide margin among the continents in terms of absolute population. Future development of Chinese population The Chinese population reached a maximum of 1,412.6 million people in 2021 but decreased by 850,000 in 2022 and another 2.08 million in 2023. Until 2022, China had still ranked the world’s most populous country, but it was overtaken by India in 2023. Apart from the population decrease, a clear growth trend in Chinese cities is visible. By 2024, around 67 percent of Chinese people lived in urban areas, compared to merely 36 percent in 2000.

Environmental degradation is proportional to the number of humans. Despite a general decrease in birth rates, the global population continues to grow. The tendencies of decrease are insufficient to achieve sustainability within a realistic time frame. High fertility is used for geopolitical advance and should be counteracted. In countries with insufficiently observed human rights, de facto reproductive coercion is used for birth rate elevation. International conflicts are motives to boost fertility, since the military needs young people. Birth control has been rejected in some countries on the grounds of presumed national interests, such as stronger defences and sovereignty, which can be bolstered by demographic growth. Smouldering international conflicts contribute to birth rate elevation in some regions. Of note, durable peace is needed to accomplish large environment protection initiatives, in particular, nuclear, thermonuclear, hydroelectric power plants, and other energy sources instead of oil and coal. Notwithstanding the prospects of cheaper and cleaner energy, there is currently no solution to a decline in regional and global populations. It seems to be inevitable that the global human population will become reduced during the present century. How this happens may be to some extent within our control. It will not remain so indefinitely.

We developed analytical models to describe dynamics of the Rocky Mountain Arsenal mule population. Our objectives were: 1) To estimate carrying capacity of the Arsenal using existing data on population composition and performance. 2) To estimate the proportion of the population that must be infertile to maintain the population at approximately half of carrying capacity. 3) To estimate the delivery rate and the number of animals that must be treated annually to maintain the population at half of carrying capacity. 4) To compare the effort required to stabilize the population using lifetime duration contraceptives with the effort required to stabilize the population using culling. Here, we summarize our progress toward these objectives.

AbstractUnderstanding the impact of herbivory on plant populations is a fundamental goal of ecology. Damage to individual plants can be visually striking and affect the fates of individuals, but these impacts do not necessarily translate into population-level differences in vital rates (survival, growth, or fecundity) or population growth rates. In biological control of weeds, quantitative assessments of population-level impacts of released agents on both target invasive plants and native, nontarget plants are needed to inform evaluations of the benefits and risks of releasing agents into new regions. Here we present a 3-yr experimental demographic field study using the European root-feeding biocontrol weevil, Mogulones crucifer, first released in Canada in 1997 to control the invasive weed Cynoglossum officinale (Boraginaceae). Mogulones crucifer is an effective “search and destroy” agent in Canada, but sporadically feeds, oviposits, and develops on native nontarget Boraginaceae. We investigated the population-level impacts of this biocontrol insect on its target weed and a native nontarget plant, Hackelia micrantha (Boraginaceae), by releasing large numbers of weevils into naturally occurring patches of H. micrantha growing isolated from or interspersed with C. officinale. We followed the fates of individual plants on release and nonrelease (control) sites for two transition years, developed matrix models to project population growth rates (λ) for each plant species, and examined the contributions from differences in vital rates to changes in λ using life table response experiments (LTRE). In contrast to studies of the insect–plant interaction in its native range, as a biocontrol agent, M. crucifer increased mortality of C. officinale rosettes in the year immediately following release, depressing the weed's λ to below the population replacement level. However, λ for H. micrantha was never depressed below the replacement level, and any differences between release and nonrelease sites in the nontarget could not be explained by significant contributions from vital rates in the LTRE. This study is the first to simultaneously and experimentally examine target and nontarget population-level impacts of a weed biocontrol insect in the field, and supports the theoretical prediction that plant life history characteristics and uneven herbivore host preferences can interact to produce differences in population-level impacts between target and nontarget plant species.

Temperature is hypothesized to contribute to increased pathogenicity and virulence of many marine diseases. The sea louse (Lepeophtheirus salmonis) is an ectoparasite of salmonids that exhibits strong life-history plasticity in response to temperature; however, the effect of temperature on the epidemiology of this parasite has not been rigorously examined. We used matrix population modelling to examine the influence of temperature on demographic parameters of sea lice parasitizing farmed salmon. Demographically-stochastic population projection matrices were created using parameters from the existing literature on vital rates of sea lice at different fixed temperatures and yearly temperature profiles. In addition, we quantified the effectiveness of a single stage-specific control applied at different times during a year with seasonal temperature changes. We found that the epidemic potential of sea lice increased with temperature due to a decrease in generation time and an increase in the net reproductive rate. In addition, mate limitation constrained population growth more at low temperatures than at high temperatures. Our model predicts that control measures targeting preadults and chalimus are most effective regardless of the temperature. The predictions from this model suggest that temperature can dramatically change vital rates of sea lice and can increase population growth. The results of this study suggest that sea surface temperatures should be considered when choosing salmon farm sites and designing management plans to control sea louse infestations. More broadly, this study demonstrates the utility of matrix population modelling for epidemiological studies.

According to latest figures, the Chinese population decreased by 1.39 million to around 1.408 billion people in 2024. After decades of rapid growth, China arrived at the turning point of its demographic development in 2022, which was earlier than expected. The annual population decrease is estimated to remain at moderate levels until around 2030 but to accelerate thereafter. Population development in China China had for a long time been the country with the largest population worldwide, but according to UN estimates, it has been overtaken by India in 2023. As the population in India is still growing, the country is very likely to remain being home of the largest population on earth in the near future. Due to several mechanisms put into place by the Chinese government as well as changing circumstances in the working and social environment of the Chinese people, population growth has subsided over the past decades, displaying an annual population growth rate of -0.1 percent in 2024. Nevertheless, compared to the world population in total, China held a share of about 17 percent of the overall global population in 2024. China's aging population In terms of demographic developments, the birth control efforts of the Chinese government had considerable effects on the demographic pyramid in China. Upon closer examination of the age distribution, a clear trend of an aging population becomes visible. In order to curb the negative effects of an aging population, the Chinese government abolished the one-child policy in 2015, which had been in effect since 1979, and introduced a three-child policy in May 2021. However, many Chinese parents nowadays are reluctant to have a second or third child, as is the case in most of the developed countries in the world. The number of births in China varied in the years following the abolishment of the one-child policy, but did not increase considerably. Among the reasons most prominent for parents not having more children are the rising living costs and costs for child care, growing work pressure, a growing trend towards self-realization and individualism, and changing social behaviors.

The global population health management systems market has been witnessing significant growth, with a market size valued at approximately USD 34.8 billion in 2023. Projections indicate that this market is expected to experience a robust CAGR of 13.5% from 2024 to 2032, reaching an estimated market size of USD 104.5 billion by 2032. The primary growth factors driving this optimistic forecast include the increasing demand for efficient healthcare delivery systems, the need for cost reduction in healthcare services, and the growing emphasis on patient-centered care. As the global healthcare sector transitions towards value-based care models, population health management systems are becoming instrumental in facilitating the shift by enabling healthcare providers to manage, analyze, and optimize the health of entire populations.
One of the major growth drivers in the population health management systems market is the rising prevalence of chronic diseases and the aging population worldwide. The increasing incidence of conditions such as diabetes, cardiovascular diseases, and respiratory disorders necessitates comprehensive health management strategies that can effectively track and manage patient health data. Population health management systems enable healthcare providers to integrate and analyze this data, leading to improved patient outcomes and more efficient use of healthcare resources. Additionally, the aging population presents a unique challenge as older adults generally require more frequent and intensive healthcare services, further driving the demand for robust health management solutions.
Another significant growth factor is the ongoing advancements in healthcare IT and data analytics technologies, which are critical enablers of population health management systems. The integration of advanced analytics, artificial intelligence, and machine learning technologies into these systems allows for more precise and predictive insights, enabling healthcare providers to proactively manage patient health and identify potential health risks before they escalate into severe conditions. The adoption of electronic health records (EHRs) and interoperability standards is also contributing to the seamless exchange of health data across various healthcare settings, enhancing the effectiveness of population health management initiatives.
The push towards value-based healthcare models is also fueling the growth of the population health management systems market. As healthcare systems worldwide shift from fee-for-service to value-based care, there is an increased need for solutions that can help healthcare providers meet quality metrics while controlling costs. Population health management systems offer the tools necessary to align healthcare delivery with these new reimbursement models by facilitating the coordination of care, improving patient engagement, and ensuring compliance with regulatory requirements. Moreover, government initiatives aimed at improving healthcare access and quality, particularly in developing regions, are expected to further boost the adoption of these systems.
In terms of regional outlook, North America currently dominates the market, largely due to the presence of a well-established healthcare infrastructure, high adoption of advanced healthcare technologies, and favorable government initiatives promoting value-based care. However, other regions, particularly the Asia Pacific, are expected to witness significant growth during the forecast period. Factors such as the increasing healthcare expenditure, rising awareness about population health management, and the burgeoning demand for healthcare IT solutions in countries like China and India are driving this growth. Additionally, Europe and Latin America are also anticipated to contribute to market expansion owing to the increasing focus on improving healthcare delivery and the rising prevalence of chronic diseases.
The population health management systems market is segmented by component into software and services, each playing a crucial role in the overall functioning and effectiveness of these systems. The software segment encompasses a wide range of applications, including data analytics, care management, and patient engagement platforms, which are essential for collecting, analyzing, and utilizing healthcare data to improve patient outcomes. These software solutions are being constantly upgraded with advanced features such as predictive analytics and artificial intelligence to provide deeper insights into patient health trends and facilitate proactive interventions.

Life Table Data: Field-based, partial life table data for immature stages of Bemisia tabaci on cotton in Maricopa, Arizona, USA. Data were generated on approximately 200 individual insects per cohort with 2-5 cohorts per year for a total of 44 cohorts between 1997 and 2010. Data provide the marginal, stage-specific rates of mortality for eggs, and 1st, 2nd, 3rd, and 4th instar nymphs. Mortality is characterized as caused by inviability (eggs only), dislodgement, predation, parasitism and unknown. Detailed methods can be found in Naranjo and Ellsworth 2005 (Entomologia Experimentalis et Applicata 116(2): 93-108). The method takes advantage of the sessile nature of immature stages of this insect. Briefly, an observer follows individual eggs or settled first instar nymphs from natural populations on the underside of cotton leaves in the field with a hand lens and determines causes of death for each individual over time. Approximately 200 individual eggs and nymphs are observed for each cohort. Separately, densities of eggs and nymphs are monitored with standard methods (Naranjo and Flint 1994, Environmental Entomology 23: 254-266; Naranjo and Flint 1995, Environmental Entomology 24: 261-270) on a weekly basis.
Matrix Model Data: Life table data were used to provide parameters for population matrix models. Matrix models contain information about stage-specific rates for development, survival and reproduction. The model can be used to estimate overall population growth rate and can also be analyzed to determine which life stages contribute the most to changes in growth rates.

Rapid population growth in developing countries in the middle of the 20th century led to fears of a population explosion and motivated the inception of what effectively became a global population-control program. The initiative, propelled in its beginnings by intellectual elites in the United States, Sweden, and some developing countries, mobilized resources to enact policies aimed at reducing fertility by widening contraception provision and changing family-size norms. In the following five decades, fertility rates fell dramatically, with a majority of countries converging to a fertility rate just above two children per woman, despite large cross-country differences in economic variables such as GDP per capita, education levels, urbanization, and female labor force participation. The fast decline in fertility rates in developing economies stands in sharp contrast with the gradual decline experienced earlier by more mature economies. In this paper, we argue that population-control policies likely played a central role in the global decline in fertility rates in recent decades and can explain some patterns of that fertility decline that are not well accounted for by other socioeconomic factors.
