UN Principles and Recommendations for Population and Housing Censuses, Revision 3 (https://unstats.un.org/unsd/demographic-social/Standards-and-Methods/files/Principles_and_Recommendations/Population-and-Housing-Censuses/Series_M67rev3-E.pdf)

UN P&R Rev.3 (ST/ESA/STAT/SER.M/67/Rev.3, 2017) prescribes five minimum marital-status categories in paragraph 4.164: Single (never married), Married, Married but separated, Widowed and not remarried, Divorced and not remarried. UN P&R does not assign letter codes to these categories. The single-letter codes (S, M, W, D, L) that appear in the system_mappings below are provenance of HL7 v3 / FHIR R4 and OpenSPP, not of UN P&R. PublicSchema adds consensual_union as an extension beyond the UN P&R minimum because most national registries and operational MIS systems represent it as a distinct status; UN P&R itself discusses consensual union separately in paragraph 4.171 as a related but distinct variable.
