<abstract><title style='display:none'>Abstract</title>The present study attempts to analyze the essential characteristics of the global problems in the development of human society at the present stage and to highlight the place of the demographic problem as an objective factor for the existence of modern civilization. It clarifies the criteria for determining a problem as a global one and makes classification from a geographic point of view. It identifies the causes for the demographic problem, analyses and specifies its different dimensions at the global, regional and national levels.</abstract>

Article Publication Charges (APC) OA Text journals are open access, we do not charge the end user when accessing a manuscript or any article. This allows the scientific community to view, download, distribution of an article in any medium, provided that the original work is properly cited. In line with other open access journals we provide a flat fee (EUR 120.00) submission structure on the acceptance of a peer-reviewed article which covers in part the entirety of the publication pathway (the article processing charge). The process includes our maintenance, submission and peer review systems and international editing, publication and submission to global indexing and tracking organisations and archiving to allow instant access to the whole article and associated supplementary documents. Archiving Sciendo archives the contents of this journal in <A href="https://www.portico.org/">Portico</A> - digital long-term preservation service of scholarly books, journals and collections. Plagiarism Policy The editorial board is participating in a growing community of <A href="https://www.crossref.org/services/similarity-check/">Similarity Check System's</A> users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.
