Mae hunaniaeth rhywedd ar wahân i gyfeiriadedd rhywiol,[13] a gall pobl drawsryweddol fod yn rhan o unrhyw gyfeiriadedd rhywiol. Cyferbyn i drawsrywedd yw cydrywedd, sy'n disgrifio pobl y mae eu hunaniaeth rhywedd yn cyfateb i'r rhyw a bennwyd.[14][15]
Amrywia ystadegau ar y nifer o bobl drawsryweddol yn eang,[16] yn rhannol oherwydd amrywiaeth diffiniadau o drawsrywedd.[17] Mae rhai gwledydd, megis Canada, yn casglu data cyfrifiad ar bobl drawsryweddol.[18] Yn gyffredinol, darganfyddir hunaniaeth drawsryweddol mewn llai nag 1% o boblogaeth y byd, â ffigurau yn amrywio o <0.1% i 0.6%.[19][20][21][22] Mae Cyfrifiad Cymru a Lloegr yn cynnwys cwestiwn am hunaniaeth rhywedd ers 2021[23][24], dywedodd 0.5% o'r boblogaeth nad yw'r rhywedd y maent yn uniaethu ag ef yn yr un peth a'r rhyw gofrestrwyd pan gawsant eu geni.
Mae llawer o bobl drawsryweddol yn wynebu gwahaniaethu yn y gweithle,[25] wrth ddefnyddio gwasanaethau[26] ac mewn gofal iechyd.[27] Yn llawer o leoedd, nis amddiffynnir rhag gwahaniaethu yn gyfreithiol.[28]

It is sometimes said that Virginia Prince (1976) popularized the term, but history shows that many transgender people advocated the use of this term much more than Prince.
