Background: Demography is a uniquely empirical research area amongst the social sciences. We posit that the same principle of empiricism should be applied to studies of the population sciences as a discipline, contributing to greater self-awareness amongst its practitioners.
Objective: The paper aims to include measurable data in the study of changes in selected demographic paradigms and perspectives.
Methods: The presented analysis is descriptive and is based on a series of simple measures obtained from the free online tool Google Books Ngram Viewer, which includes frequencies of word groupings (n-grams) in different collections of books digitised by Google.
Results: The tentative findings corroborate the shifts in the demographic paradigms identified in the literature -- from cross-sectional, through longitudinal, to event-history and multilevel approaches.
Conclusions: These findings identify a promising area of enquiry into the development of demography as a social science discipline. We postulate that more detailed enquiries in this area in the future could lead to establishing History of Population Thought as a new sub-discipline within population sciences.
