Analytic epidemiological studies aim to investigate and identify factors associated with the presence of disease within populations, through the investigation of factors which may vary between individual members of these populations. These factors can be classified as one of the components of the 'epidemiological triad' of '''Host, Agent and Environment''', many of which are closely interrelated with each other:

Analytic epidemiological studies aim to investigate and identify factors associated with the presence of disease within populations, through the investigation of factors which may vary between individual members of these populations. Details on study designs appropriate for these investigations are given [[Study design#Analytic studies|elsewhere]]. Conceptually, this involves investigating the disease experience amongst different 'groups' of animals within an overall population, distinguished according to the factor(s) of interest. These factors can be classified as one of the components of the 'epidemiological triad' of '''Host, Agent and Environment''', many of which are closely interrelated with each other:
