(Data Analysis) A trend existing to some characteristic or phenomena over a relatively long period of time. Secular trends represent an important underpinning to any form of analysis as once such a trend is determined, deviations or perturbations from this trend may only be temporary and, if caused by man's activities, may not be reasonably sustainable in the long term.
