title: The use of sigmoids in modelling and forecasting human populations.
abstract: "The aim of this paper is to present a review that might justify giving further consideration to the use of sigmoids in contemporary population modelling and forecasting.  To do this a brief account is given of the historical development of these models, pointing out why demographers have viewed these trend models with scepticism.  Most of the paper is devoted to showing that, despite these criticisms, sigmoid-based trend models are useful practical tools for the demographer."  Examples using data for various countries are presented.
