demography: age, sex, ethnic group, country of birth, religion, marital status, population mobility.
The difference between the two is that the DMT shows how birth and death rates change as country goes through different stages of development while the ETM comes from epidemiology (branch of medical science concerned with the incidence, distribution and control of diseases that affect large numbers of people) and
Epidemiologists are less interested in population in itself and more in the diseases that affect individuals. It is more focused on the 'micro-level' (the level of individuals), whereas demographers are more interested in the 'macro-level' (the aggregate level).

Population and epidemiology studies involve studying the health of populations—both at specific time points and over longer periods of time—to uncover patterns, trends, and outcomes that may be applicable to the general population.The third component of epidemiology, the Greek root logos, means study. Demos and another Greek root, graphein (to write, draw), combine to form the term demography, a kindred population-based science.
The epidemiology of depression has been studied across the world. Depression is a major cause of morbidity and mortality worldwide, as the epidemiology has shown. Lifetime prevalence estimates vary widely, from 3% in Japan to 17% in India. Epidemiological data shows higher rates of depression in the Middle East, North Africa, South Asia and U.S.A than in other regions and countries. Among the 10 countries studied, the number of people who would experience depression during their lives falls within an 8–12% range in most of them.
The epidemiology of herpes simplex is of substantial epidemiologic and public health interest. Worldwide, the rate of infection with herpes simplex virus—counting both HSV-1 and HSV-2—is around 90%. Although many people infected with HSV develop labial or genital lesions, the majority are either undiagnosed or display no physical symptoms—individuals with no symptoms are described as asymptomatic or as having subclinical herpes.

Pneumonia is a common respiratory infection, affecting approximately 450 million people a year and occurring in all parts of the world. It is a major cause of death among all age groups, resulting in 1.4 million deaths in 2010 and 3.0 million deaths in 2016.
