driven primarily by high birth rates in developing countries and advancements in healthcare. According to the United Nations, the global population surpassed 8 billion in 2023, marking a critical milestone in human history. This growth, however, is unevenly distributed across continents and countries, leading to varied population densities and urban pressures.

Surface area and population density play vital roles in shaping the demographic and economic landscape of each country. For instance, countries with large land masses such as Russia, Canada, and Australia have low population densities despite their significant populations, as vast portions of their land are sparsely populated or uninhabitable. Conversely, nations like Bangladesh and South Korea exhibit extremely high population densities due to smaller land areas combined with large populations.

Population density, measured as the number of people per square kilometer, affects resource availability, environmental sustainability, and quality of life. High-density areas face greater challenges in housing, infrastructure, and environmental management, often experiencing increased pollution and resource strain. In contrast, low-density areas may struggle with underdeveloped infrastructure and limited access to services due to the dispersed population.

Urbanization trends are another important aspect of these dynamics. As people migrate to cities seeking better economic opportunities, urban areas grow more densely populated, amplifying the need for efficient land use and sustainable urban planning. The UN reports that over half of the world’s population currently resides in urban areas, with this figure expected to rise to nearly 70% by 2050. This shift requires nations to balance population growth and density with sustainable development strategies to ensure a higher quality of life and environmental stewardship for future generations.

Through an understanding of population size, surface area, and density, policymakers can better address challenges related to urban development, rural depopulation, and resource allocation, supporting a balanced approach to population management and economic development.

Climate and land use/land cover change are expected to influence the stationary nonbreeding distributions of 4 Nearctic-Neotropical migrant bird species experiencing population declines: Canada Warbler (Cardellina canadensis), Cerulean Warbler (Setophaga cerulea), Golden-winged Warbler (Vermivora chrysoptera), and Wood Thrush (Hylocichla mustelina). Understanding how and where these species’ distributions shift in response to environmental drivers is critical to inform conservation planning in the Neotropics. For each species, we quantified current (2012-2021) and projected future (2050) suitable climatic and land use/land cover conditions as components of stationary nonbreeding distributions. Multi-source occurrence data were used in an ensemble modeling approach with covariates from 3 global coupled climate models (CCSM-ESM2, FIO-ESM-2-0, MIROC-ES2L) and 2 shared socioeconomic pathways (SSP2-RCP4.5, SSP5-RCP8.5) to predict distributions in response to varying climatic and land use/lan..., Bird Occurrence Data We obtained current (2012-2021) bird occurrence data containing only Neotropical presence records from eBird (accessed in January 2023; Sullivan et al. 2009) and supplemented with species-specific georeferenced occurrence datasets to bolster presence record sample sizes and the spatial representation of records. 2012-2021 was identified as the ‘current’ timeframe to capitalize on increased user engagement with eBird and align with prior research (Hightower et al. 2023). Date ranges for the stationary nonbreeding period were defined using expert input (N. Bayly, E. Cohen, I. Davidson, A. González, J. Hightower, J. L. Larkin, E. Montenegro, D. Raybuck, A. Roth, C. Rushing, C. Stanley, R. L. M. Stewart, and S. Wilson personal communication) to assess frequency distributions of daily presence records in the current timeframe. Experts emphasized date selection 2 weeks before or after most birds initiated or completed migration through the Neotropical flyway to minimize ..., , # Nonbreeding distributions of four declining Nearctic-Neotropical migrants are predicted to contract under future climate and socioeconomic scenarios

Description of the data and file structure

The following data are available for use: covariates, spatial extents, presence record CSVs, and Honduras focal areas in the 'Processes to Identify Near-term Conservation Priority Areas' methods section. Covariates are available for the current (2012-2021) and future (2050) time periods. The current timeframe for Brodie et al. 2024 was designated as 2012-2021 to align with prior research and capitalize on increased user engagement with eBird. The 2050 data is split into SSP2-RCP4.5 (best-case) and SSP5-RCP8.5 (worst-case) climate and socioeconomic scenarios. The best-case represents a future where climate-smart practices increase and non-renewable resource use declines. In contrast, the worst-case represents ...

The statistic shows the gross domestic product (GDP) per capita in Canada from 1987 to 2024, with projections up until 2030. In 2024, the gross domestic product per capita in Canada was around 54,473.19 U.S. dollars. Canada's economy GDP per capita is a measurement often used to determine economic growth and potential increases in productivity and is calculated by taking the GDP and dividing it by the total population in the country. In 2014, Canada had one of the largest GDP per capita values in the world, a value that has grown continuously since 2010 after experiencing a slight downturn due to the financial crisis of 2008. Canada is seen as one of the premier countries in the world, particularly due to its strong economy and healthy international relations, most notably with the United States. Canada and the United States have political, social and economical similarities that further strengthen their relationship. The United States was and continues to be Canada’s primary and most important trade partner and vice versa. Canada’s economy is partly supported by its exports, most notably crude oil, which was the country’s largest export category. Canada was also one of the world’s leading oil exporters in 2013, exporting more than the United States. Additionally, Canada was also a major exporter of goods such as motor vehicles and mechanical appliances, which subsequently ranked the country as one of the world’s top export countries in 2013.

Kanadas Bevölkerungswachstum setzt sich fort und das Land erreicht 2023 eine Gesamtbevölkerung von geschätzt rund 39,3 Millionen Einwohnern. Damit hat sich die Einwohnerzahl Kanadas binnen eines Jahres um rund 480.000 Menschen erhöht. Für das Jahr 2024 wird eine Gesamtbevölkerung Kanadas von rund 39,7 Millionen Menschen prognostiziert. Die Geburtenrate ist dabei nur durchschnittlich hoch - das Wachstum resultiert vor allem aus der Einwanderung. Hohe Lebensqualität in Kanada zieht Zuwanderer an Kanada ist seit jeher ein klassisches Einwanderungsland und bereits seit 1971 ein offiziell multikulturelles Land – der Multikulturalismus ist gesetzlich in der Verfassung verankert. Die Lebenszufriedenheit der Kanadier ist sehr hoch und das Land wird international geachtet, was sich auch im positiven Einfluss Kanadas auf die Weltgemeinschaft ausdrückt. Nur zwei von vielen Gründen warum Kanada für Zuwanderer so attraktiv ist:

Natürliche Bevölkerungsentwicklung oder Migration? Grundsätzlich kann bei der Bevölkerungsentwicklung zwischen dem natürlichen Bevölkerungswachstum und der Zuwachsrate (allgemeines Bevölkerungswachstum) unterschieden werden:natürliches Bevölkerungswachstum

Das natürliche Bevölkerungswachstum ergibt sich aus der Verrechnung von Geburten und Todesfällen.

Zuwachsrate

Bei der Zuwachsrate wird das natürliche Bevölkerungswachstum mit dem Migrationssaldo, also dem Saldo aus Immigration (Einwanderung) und Emigration (Auswanderung) verrechnet.

Zusammenhang

Industrieländer benötigen im Allgemeinen eine Geburtenrate (Fertilitätsrate) von durchschnittlich 2,1 Kindern je Frau, um den Bestand der Population konstant zu halten (Bestandserhaltungsniveau). Für ein positives Bevölkerungswachstum wird dementsprechend eine höhere Geburtenrate oder ein positiver Migrationssaldo benötigt.
