There are a large number of people and records per person in the SEER-Medicare data. Given the vast amount of data, the term SEER-Medicare data actually refers to a series of files. One file includes SEER data. The remaining files are the Medicare files for specific types of service, e.g. hospital, physician, outpatient, etc.There are two cohorts of people included in the SEER-Medicare data -- persons with cancer and a random sample of Medicare beneficiaries who do not have cancer. The "non-cancer" group is drawn from a random 5 percent sample of Medicare beneficiaries residing in the SEER areas.
The SEER-Medicare data have great potential utility for a variety of analyses.
