What is the difference between "repeated cross-section" and "pooled cross-section"?
Pooled cross-section is defined e.g. here as "randomly sampled cross sections of individuals at different points in time. Example: Current population survey (CPS) in 1978 and 1988".
Repeated cross-section is defined e.g. here as "one type of survey design and uses data, in which the same information is asked to an independent sample at each wave". Which is the same as the previous definition for "pooled cross-section".
This is an answer to a question about "pooled cross sectional data" and the answer uses the term "repeated cross sections".
So it looks like the two terms are synonymous?
