2018-04-17 The data files were updated to include information for 2014.
2017-06-16 An incompatibility in the sequence numbers between the archived USSC data and the AOSC dyads involving an extra non-identifying zero in the USSC dyad sequence number was found. Dataset 4, AO Cases OUT SAF and USSC OUT SAF, has been corrected and updated as a result.
2016-09-19 The JWSCORE and MAGFLAG variables, present in previous dyad linking files, have been removed to ease use of the linking files. In addition, the data files were updated to include information for 2013.

2011-06-14 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Created variable labels and/or value labels.
