A census is a cross-sectional study of the full population, where every member of the target population is included. It differs from a cohort study or panel study, which follow selected individuals over time, and a trend survey, which capture changes in a subset of the population over time. The purpose of a census is to collect information about the entire population, rather than a sample of the population.
