  Following the recent publication of our book on Exploring the Health State of
a Population by Dynamic Modeling Methods in The Springer Series on Demographic
Methods and Population Analysis (DOI 10.1007/978-3-319-65142-2) we provide this
brief presentation of the main findings and improvements regarding the Health
State of a Population. (See at: http://www.springer.com/gp/book/9783319651415).
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 (see Figure 13 and
http://www.smtda.net/demographics2018.html). 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. Keywords: Health State and Survival Curves,
Health status of a population, First exit time stochastic theory, stochastic
simulations of health state, Age at Maximum Curvature, Healthy Life Expectancy
and HALE, Standard Deviation, Health State Curves, Maximum human lifespan and
other.
