Biometry  (BIOMETRY)

The study of relations between demographic phenomena on the one hand and economic and social phenomena on the other forms another branch of the subject. The terms economic demography1 and social demography2 have been used by some writers. Demography also deals with the study of population quality3. 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 (911-1) which are the subject-matter of population genetics4. Human ecology5 is the study of the distribution and organization of communities with attention to the operation of competitive and co-operative processes and has part of its subject matter common with demography, as has biometry6 or biometrics6 which deals with the application of statistical methods to all forms of biological research.
