... that the model investigated represents only a reasonable first step in the direction of reality from the unrealistic assumption that mortality and fertility do not change with passing time. It is shown that this general model can lead to self-excited, persistent oscillations (called limit cycles in mathematical...

... cycles,” in births. Frauenthal and Swick recently reestimated a continuous-age version of Lee’s basic cohort model with U.S. series and, contrary to Lee’s original findings, concluded that “limit cycles oscillations have been occurring in U.S. births.” This article disputes their conclusion, ascribing...

There are other possibilities not illus- trated in Figures 2 and 3: the equilibrium point may be unstable, in which case violent oscillations may lead to extinc- tion (if B, :s; 0) ; or a stable "limit cycle" may occur...

.... These input variables were tried on a life-table population dis- tributed by sex, age, and marital status (see Grabill, 1945, Table 2). After ten repetitions of the cycle, each consisting of ten two-year periods, the growth multipliers were found to stabi- lize themselves within the set limits (e.g., 0.00001...

... the structure of the birth sequence. We know that B(t) can be calculated, but cannot readily explain that B(t) has certain features as a result of certain features of c/J(a, t), except in very limited special cases. For example, when c/J(a, t) is constant, B(t) is an exponential, with a rate of change r...

... doubt exists, however, that these factors, inter-correlated in varying degree, have been fostering an attitude oriented to a strict limitation of family size. Al- though this interpretation serves ade- quately to explain fertility trends until World War II, it turns out to be incon- sistent with recent...
