Data management of large, complex surveys like the HRS is a fairly difficult and time-consuming task. The HRS staff endeavors to produce a public-release data set as soon as possible (and they produce them much faster than many other publicly funded data collections!), so they release an early version of the data: Core Early Release (V1.0)*. The updated RAND files tend to follow soon after.
HRS does an early release to get the data to the public as fast as possible, but HRS staff continues to process the data until they have a final data release. Sometimes the early release is ultimately designated as the final release – you’ll know this is the case if you see “Final V1.0” followed by the date of release. But sometimes there are issues in the data that need to be resolved. These tend to be the result of programming errors, but there are sometimes problems with the data that the HRS staff catch during data inspections after the early release (e.g., a case is designated as a non-sample member after closer inspection). So, in some years the final release is a V1.0, but in other years it may be a V2.0 or V3.0. And in rare cases the final release is a V4.0 or V5.0.
