Cross-sectional studies are related to sample surveys. In both types of studies a sample S is taken from the target population U, for example by one of the sampling plans presented in Sect. 12.2.

In a cross-sectional study, all in a given population or a random sample from this population define the source population. The disease and its possible determinants are all recorded at a given point in time. This introduces a temporal ambiguity in the possible cause–effect association and for this reason most cross-sectional studies have survey ...
