The periodical literature of demography and Bradford's law

摘要

This paper presents a statistical analysis of the journals and papers abstracted in Population Index, 1984. A Bradford distribution is fitted to the papers in all the journals regularly scanned by Population Index, as well as in the journals specifically designated as demography. The fit of these distributions, and in particular the second one, is remarkably close. A core of journals for demography is identified. A breakdown of the journals and the papers published in them by the journal's field is presented and discussed. Data on the distribution of journals by country of publication are also given. An attempt is made to correlate the journal's productivity according to Population Index with the citation impact according to Social Sciences Citation Index.
