[Turning points in demographic trends].
A method for estimating demographic turning points using spline functions is described.  It involves using a nonlinear least squares method to estimate the points in time at which such turning points occur.  "The method is employed for assessing turning points in the trends of the numbers of live births, deaths, marriages, immigrants, emigrants and internal migrants after the Second World War in the Netherlands.  In general the trends can be described adequately by specifying three turning points after 1950."  (summary in ENG)
