Starting with the 1973-2011 SEER Research Data (November 2013 submission), additional Collaborative Stage Site-Specific Factor (CS SSF) fields are available in the standard research data for analysis in the rate, frequency and case listing sessions.

The following spreadsheets provide the list of all the CS SSF fields available in the SEER Research Data:
