Author Guidelines

Before submitting a manuscript, please ensure that you are registered as an author. Submissions can be made online. In case of any difficulties please contact us.

CPoS only considers submissions for review that meet the criteria listed above. Authors of (conditionally) accepted papers are required to also meet the requirements listed below before submitting a final version.

CPoS reserves the right to withdraw articles without the consent of the authors if they do not comply with the author guidelines or good scientific conduct according to the rules stated in the Code of Good Academic Practice and Regulations on Academic Misconduct at the Federal Institute for Population Research (BiB).

CPoS supports reproducible research and strongly encourages authors to submit data, code and a metadata document as supplementary files.

In order to ensure that CPoS has a uniform layout, all figures will be re-drawn by the CPoS Team. We therefore ask you to submit all data shown in tables and figures as data files (preferably .xls files). Please ensure that figure and table headers as well as axis titles state variable names, units and time period of the data shown. Please use “Source: own design” or “Source: own calculation based on …” to indicate your authorship of a figure or table.

Complex figures and maps should be submitted as PDF. Please use Arial fonts for text within the figures and arrange for a maximum printing size of the figure of approx. 12.2*16.5 cm. Font size and line width should be related to the given printing size. Authors will be contacted about the technical details if necessary.

METIS: Members of VG-Wort may submit their membership number in the metadata section in order to participate.

OpenAIRE: Please provide the grant number in the metadata section to fulfill deposit requirements resulting from research grants of the European Research Council or the Seventh Framework Programme.


Style Guide for References

All references in the text must be included in the reference list. Up to three authors are separated by a semicolon. More than three authors are abbreviated after the first author with “et al.” More than one entry for an author with the same year will be differentiated by a, b, etc. after the year. References in the text to more than one publication by an author are separated by a comma, and multiple references within a single set of brackets are separated by a semicolon (AuthorAa, AuthorAb year1: page-page; AuthorB et al.: year). Quotations must always be placed within double quotation marks (“).

A style sheet is available for download via the citation menue of Citavi®.

Research Articles

Papers may cover a wide range of topics in the interdisciplinary field of population studies and demographic research, either focussing on empirical analysis, conceptual theories, statistical methods or state of the art reviews. The journal particularly welcomes contributions with an international or regional comparative perspective, and findings with high policy relevance. Quantitative and qualitative approaches are equally appreciated. Contributions to the journal must not have been published beforehand. CPoS does, however, accept manuscripts which have been published as a working paper or on an archiving platform.

Demographic Trends Around the Globe

CPoS welcomes shorter papers presenting new descriptive findings on demographic change and its challenges around the globe. Papers in this category present a new empirical finding that relates to population change around the globe and its societal consequences in a specific country or a group of countries. Manuscripts will undergo a fast-track double blind peer review process. The main text should not exceed 5,000-6,000 words.

Privacy Statement

Notes on Data Protection and Privacy Policy

The editorial team of Comparative Population Studies (CPoS) considers the protection of personal data to be a very serious matter. We are thus committed to protecting your privacy and fully adhere to the data protection provisions. With these notes we also fulfil our information obligations regarding the collection of personal data, which are laid down in Article 13 of the European Union’s General Data Protection Regulation (GDPR).

This privacy policy refers to the website

CPoS is published by the Federal Institute for Population Research. The general privacy policies of the institute can be found here:

Personal user data will be stored on a server at Freie Universität Berlin, Kaiserswerther Str. 16-18, 14195 Berlin, Germany. The Freie Universität Berlin is the respective data recipient according to the General Data Protection Regulation (GDPR).

Personal Data

Personal information is information that can be used to identify you. This includes information such as your name, postal or IP address (if not anonymized), telephone number, and e-mail address, but not information that is not associated with your identity (such as anonymous log files in which the used browser types are logged).

We store your data only at your request and to the extent needed (for example, for registration as an author, reader or reviewer) or for data backup. The specific use of such data is indicated in the respective context in this privacy statement.

When we collect and utilize personal data, we confine ourselves strictly to what is technically necessary and permitted by law. We collect and use personal data only with your prior consent or where allowed by law. It is important to us that you understand why we collect data and what we use them for. More information can be found below.

We collect information from you when you access the above-named domain. For purposes of identification and tracking unauthorized access attempts to this domain as well as for purposes of optimization of web-based services in connection with the use of the web pages of the above-named domain, user data are stored and used to create anonymous access statistics. This information is collected automatically when entering our website. It serves the provision of the website in fulfilment of our public duties, Article 6 (1) lit. e) of the General Data Protection Regulation (GDPR).

The following data processing may occur when entering this website:

Use of Cookies

Like other organizations, we use so-called cookies. Cookies are small files that are stored in special filed directories on your computer (unless you block them) and collect data. Information about your visit to our website can be stored in cookies. Our cookies do not contain personal data (such as IP addresses or login data), but rather only anonymous session IDs. Some of the cookies we use will remain on your computer so that our web server can recognize your computer the next time you visit. Most browsers (Internet Explorer, Firefox, Opera, etc.) are set by default to accept cookies. You can set your browser to reject cookies or request a confirmation from you. However, if you disable or reject cookies, it is possible that you will not be able to use certain features of the website. Cookies are required to maintain a login session in PKP applications. The legal basis for the processing of personal data using cookies is Article 6 (1) lit. e) of the General Data Protection Regulation (GDPR).

Usage Statistics Information

In order to be able to analyse usage and impact of our journal and the published articles as well as optimization of web-based services, we collect and log access to the journal’s homepage, issues, articles, galleys and supplementary files. In the process all data is anonymised. No personal information is logged. IP addresses are logged and are then automatically anonymised by being hashed (using SHA 256) in combination with a secure 64 characters long salt that is automatically randomly generated and overridden on a daily basis. Therefore IP addresses cannot be reconstructed.

The following information is collected next to the anonymised IP addresses:

  • Access type (i.e. administrative)
  • Request time
  • Requested URL
  • HTTP status code
  • Browser

The collected data is only used for evaluation purposes mentioned in this privacy statement. IP addresses are neither assigned to registered nor to non-registered users of the website. It is technically impossible to trace a specific set of data to a specific IP address.

If you wish you can opt-out of the data collection process. By clicking the opt-out button, you can actively decide against participating in the statistical analysis. When clicking the opt-out button a cookie is being created on your system to store your decision. If the privacy settings of your browser lead to cookies being automatically deleted you will have to opt-out again the next time you access this website. The cookie is only valid for one browser. If you use a different browser, you will have to opt out again. No individual information is stored within this cookie. This cookie lease is valid for one year after your last access.

Opt-Out – Link

Please bear in mind that general server logs are not affected by your decision to opt-out of the detailed evaluation process because they are crucial for operating this website.

Inquiries (via our contact address)

If you – for example as a librarian – send your inquiry via email or contact us via telephone we will store your data given in our customer management system in order to be able to answer your questions. The legal basis for the processing of personal data using a customer management system is the fulfilment of our public duties, Article 6 (1) lit. e) of the General Data Protection Regulation (GDPR).

Registering a User Account (as reader or author)

Submitting authors are also asked to enter full names and email addresses of all of their co-authors. When providing co-authors contact details you declare to have received their consent in data processing.

Co-authors do not have their own account during the editorial process and will only be contacted by the editorial team once their manuscript is submitted, an editorial decision is made, the manuscript is published, or misconduct is suspected. Author and co-author names (and affiliations) are displayed publicly alongside published manuscripts. Email addresses are not published on the website, but author contact data is included in the downloadable manuscript file as provided and approved by the authors. The rights mentioned below also apply to the co-author(s).

Transmission of Personal Data to Third Parties and Erasure of Personal Data

This journal’s editorial team uses the stored data to guide our work in publishing and improving CPoS.

Data that will assist in developing our publishing platform (Open Journal Systems) may be shared with its developer, the Public Knowledge Project (PKP), but only in an anonymized and aggregated form, with appropriate exceptions such as article metrics.

By submitting a manuscript you agree that it will undergo a plagiarism check based on Crossref Similarity Check powered by iThenticate. For this purpose the name of the first author as well as the title of the original manuscript will be shared with iThenticate.

Metadata of published manuscripts including author names are shared with third parties for DOI registration and for indexing of published content in scholarly databases such as Scopus, DOAJ, ProQuest and the like. Apart from that, the personal data will not be shared by CPoS nor will it be used for purposes other than those stated here.

Data will be stored for the purposes stated in this data protection statement and will be deleted if storage is no longer necessary for the purposes mentioned above, Article 17(1) of the General Data Protection Regulation (GDPR).
