Part of the The Springer Series on Demographic Methods and Population Analysis book series (PSDE, volume 46)


Following the recent publication of our book on “Exploring the Health State of a Population by Dynamic Modeling Methods” (DOI in “The Springer Series on Demographic Methods and Population Analysis” we provide this brief presentation of the main findings and improvements regarding the Health State of a Population. (See at:

Here the brief history of the Health State or Health Status curves for individuals and populations is presented including the main references and important figures along with an illustrated Poster.

Although the Survival Curve is known as long as the life tables have introduced, the Health State Curve was calculated after the introduction of the advanced stochastic theory of the first exit time.

The health state curve is illustrated in several graphs either as a fit curve to data or produced after a large number of stochastic realizations. The Health State, the Life Expectancy and the age at “mean zero health state” are also estimated.
