The Demography domain (DM)  is a a special-purpose domain that includes a set of essential standard variables that describe each subject in a study. Investigator and site identification: Companies use different methods to distinguish sites and investigators. CDISC assumes that SITEID will always be present, with INVID and INVNAM used as necessary. Every subject in a study must have a subject identifier (SUBJID). In some cases a subject may participate in more than 1 study. To identify a subject uniquely across all studies for all applications or submissions involving the product, a unique identifier (USUBJID) must be included in all datasets.

This is an example SDTM dataset.   Note that this SDTM This dataset includes information that is expected to be provided, but not usually collected directly on the Demography CRF.  This includes RFSTDTC, RFENDTC, RFXSTDTC, RFXENDTC, RFCSTDTC, RFCENDTC, RFICDTC. DTHDTC and DTHFL are also expected to be included. For a subject who has not died, the value of variable DTHF is null. The death date may be blank if unknown. When multiple races were self reported, the applicant recorded "MULTIPLE" as the Race and used Supplemental Qualifiers to record the self-reported race.
