When the movement of a demographic variable in time is considered, a demographic time series¹ is obtained. It is sometimes possible to decompose a time series into a trend² around which there are fluctuations³, variations³ (141-1) or deviations³ (141-2). Where such fluctuations tend to recur after certain periods, they are called periodic fluctuations⁴ or sometimes cyclical fluctuations⁴, In demography the most common period is a year, and the fluctuations in sub-periods are called seasonal fluctuations⁵. The fluctuations that remain after trend and periodic fluctuations have been eliminated are called irregular fluctuations⁶. They may be due to exceptional factors, e. g. to mobilization, or sometimes they are chance fluctuations⁷ or random fluctuations⁷.
