Below Replacement Fertility

The effect of changes in rates of mortality, fertility, and migration depend not only on the age-specific patterns and levels of these rates, but on the age structure of the population. In order to remove the influences of the age structure and concentrate on the impact of the demographic rates themselves, a common practice is to analyze the influences of the rates for a standard age structure. This paper adapts the general approach of using a standard age structure to a stationary population equivalent (SPE) model, and analyzes current population change, using the SPE model, for provinces of Canada. Below-replacement fertility levels are only partially offset by net immigration. The SPE model evidences the decrease in the eventual provincial populations brought about by the below replacement fertility. Out-migration for some provinces to other areas of Canada accentuates their eventual population decreases.

Abstract BackgroundSexually transmitted infection rates continue to increase across the US, further developing health disparities and economic burdens of disease, especially as migration occurs. In this study, we assessed the relationships among STI rates and migration at the county-level in Missouri from 2008–2017.MethodsTwo data sources were used: STI rates of chlamydia, gonorrhea, syphilis, HIV reported to Missouri DHSS and ACS 1-year county population estimates. Linear regression models and ANOVA tests were conducted in SPSS for each STI from year-to-year and 2008–2017. Covariates included in the analyzes were county-level income, employment rate, race, ethnicity, age, and percent poverty. Further, Akaike Information Criterion tests were performed to indicate the best predictor models and averaged standardized beta values.ResultsSignificant relationships among STI rates and population growth were identified. Chlamydia, syphilis, and HIV were positively associated with population growth from 2008–2017 (β = 0.15; β = 0.01; β = 0.05, respectively). Gonorrhea was negative associated with population growth (β= -0.02) but positively associated with unemployment rates (β = 0.01) highlighting the need to address population growth, as well as other variables in a population.ConclusionsThere seems to be a positive relationship among population change and rates of STIs. As populations change, rates of STIs change. Moving forward, quantitative work should be conducted in various states and the nation to understand this relationship in different contexts. Qualitative studies should assess individual county health departments, identifying strengths and weaknesses, implementation of community health improvement plans. Lastly, public policy should be implemented to buffer the impact of migration on health outcomes.

External Migration

As with many other nations in Europe, Denmark has experienced below-replacement fertility over the past three decades. The impact on population growth of the recent fertility decline to a large extent has been offset by a positive net balance of external migration. To provide a factual basis for a wide range of policy issues and social and cultural impacts we start by studying external migration, differential fertility, naturalization of foreign nationals, and population growth in the framework of multidimensional life models. Migrants and naturalized citizens tend to have reproductive behavior and sex/age profiles that differ significantly from those of the remaining population. To study some concerted demographic and social impacts of such differentials, we construct a number of midterm projections based on existing and expected development of fertility, mortality, and migration.

The Impact

This paper examines the effect of net international migration on prospective population growth and age structure in Canada for the next 50 years. It also examines the impact of international migration on provincial growth and distribution. The procedure used in this study is by comparing two projected population scenarios, one with international migration and the other without international migration, based on the latest 2005-based population projections. The analysis of the scenarios shows that the assumed level of international migration which is higher than the current level contributes to a continuous increase in population over the next 50 years, but has limited effect to prevent or offset the overall aging trend.

The Impact

Population movements can affect security in a variety of ways. Aside from altering a society’s overall balance of population and physical resources, they exert a considerable influence on the institutions of society—the state, elite recruitment and social status, the military, labor organizations and peasant villages—in a way that undermines political and social order. The consequences of population movements for security can also be seen in differential population growth and migration, differential aging of different populations, and issues of resource allocation and climate change. The work of T. R. Malthus in the early nineteenth century advanced the argument that more people would put an undesirable burden on societies, and weaken them. Julian Simon turned the Malthusian argument on its head with his claim that people were the “ultimate resource,” and that the more people were around to work on solving the globe’s problems, the more likely it was that powerful solutions would be found. The debate between Malthusians, represented by Paul Ehrlich, and Cornucopians, represented by Simon, from the 1960s to the 1990s was primarily about the impact of population on economic growth. In the 1990s, a new direction emerged in the debate on population and security. This was the argument that population growth would lead to local shortages of critical resources such as farmland, water, and timber, and that these could trigger internal conflicts and even civil wars. These conflicts arise only where states and economies are relatively weak and unable to respond to population growth.

The Impact

We provide aggregate macroeconomic evidence on how, in the long run, a diverse degree of complexity in production may affect not only the rate of economic growth, but also the correlation between the latter, population growth and the monopolistic (intermediate) markups. For a sample of Organisation for Economic Co-operation and Development (OECD) countries, we find that the impact of population change on economic growth is slightly positive. According to our theoretical model, this implies that the losses due to more complexity in production are lower than the corresponding specialization gains. Using a finite mixture model, we also classify the countries in the sample and verify for each cluster the impact that the population growth rate and the intermediate sector’s markups exert on the 5-year average real gross domestic product (GDP) growth rate.

Depopulation is understood as a real population loss in an area represented by a negative population change. In the present-day Poland, the process is particularly distinct in the economically underperforming areas situated on the peripheries of large urban centres, but some of the most populous cities are also affected by it. The purpose of the presented research using Webb’s typology was to identify Polish poviats that were depopulating in all the years from 2002 to 2014 as a result of natural population decline and negative migration balance (two-factor depopulation). In the research, special attention was given to the rate of change in the number of population (total and by age group) and to a net natural and migration loss in the selected poviats. Selected characteristics of the 2014 population age structure in Poland were also evaluated. The basis for all findings presented in the paper is vital and migratory statistics for the years 2002 to 2014 and the data on poviats’ population age structure from 2002 and 2014 published by the Central Statistical Office.

The Impact

In today’s increasingly urban world, understanding the components of urban population growth is essential. While the demographic components of natural increase and migration have received the overwhelming share of attention to date, this paper addresses the effects of administrative reclassification on urban population growth as derived from census data, which remain largely unstudied. We adopt a spatial approach, using the finest resolution US census data available for three decennial census periods, to estimate the magnitude of reclassification and examine the spatial-temporal variation in reclassification effects. We supplement the census data by using satellite-derived settlement data to further explain reclassification outcomes. We find that while 10% and 7% of the population live in areas that underwent urban/rural reclassification during the 1990–2000 and 2000–2010 time periods, respectively (with smaller fractions of corresponding land), reclassification has a substantial effect on metrics derived to characterize the urbanization process—comprising roughly 44% and 34% of total urban population growth over each period. The estimated magnitude of this effect is sensitive to assumptions regarding the timing of reclassification. The approach also reveals where, how, to what degree, and, in some part, why reclassification is affecting to the process of urbanization on the fine spatial scale, including the impact of underlying demographic processes. This research provides new directions to more effectively study coupled nature–human systems and their interactions.

Abstract. Anthropogenic dust is acknowledged as a product of human activities on disturbed soil, and is generated mainly from sensitive and fragile regions including croplands, pastures, and urbanized regions. In this study, we analyzed the behaviour of anthropogenic dust in semi-arid region of globe, and its relationship to human activities. An obvious peak in the total anthropogenic dust column, much higher magnitude than those of wet regions, was observed in semi-arid regions with population growth rates of more than 11.46 %. Four typical semi-arid regions, East China, India, North America and North Africa were selected to explore the local difference in anthropogenic dust production. The population growth rates in these areas were approximately 6.16 %, 17.71 %, 11.21 %, and 29.26 %, and the anthropogenic dust levels were 0.17 g m−2, 0.38 g m−2, 0.10 g m−2 and 0.21 g m−2, which are higher than the natural dust column burden. The anthropogenic dust column burden is positively correlated with the population and population change, indicating a contribution from human activities to the anthropogenic dust production. Based on the fact that anthropogenic dust can act as warming aerosol, the radiative effect of anthropogenic dust in semi-arid regions can not be ignored and requires further investigation.

The impact of births, deaths and migration on the growth of the population of São Paulo is examined. The causes for the changing levels of fertility and mortality are studied, as well as the social and demographic integration of European and Asian migrants. The question of literacy and its change by sex and urban and rural populations are basic themes as well. Finally the rise of secondary cities as the frontier closes is also a major concern that is examined.

Decision Making Tool

Population projections serve as a decision-making tool or as a tool to help contribute to discussions on the future of our societies. These projections are based on a series of choices made by the modeller about the projection methodology and the future trends in the population growth components (fertility, mortality and migration). To use these projections wisely, users should be aware of the impact of these choices on the results of a population projection. This article highlights the crucial role of the assumptions made on the future trends of the population growth components on the projection results, using population projections for Belgium published by national and international institutions.
