Population genetics  (POPULATION genetics)

The study of relations between demographic phenomena on one hand and economic and social phenomena on the other forms another branch of the subject. The terms economic demography 1 and social demography 2 have been used by some writers. Demography also deals with the study of population quality 3. This phrase may be used with reference to all sorts of social and personal characteristics. In a slightly different sense the term primarily refers to the distribution and transmission of hereditary characteristics (910-3) which are the subject of population genetics 4 . Human ecology 5 is the study of the distribution and organization of communities with attention to the operation of competitive and cooperative processes and has part of its subject matter in common with demography. Fields of research and methodology are even more intertwined in the case of demography and human geography 7★. It is also the case for biometry 6 or biometrics 6 and epidemiology 8★ which deal with the application of statistical methods to all forms of biological and medical research.
