Dyma restr o wledydd yn nhrefn eu dwysedd poblogaeth. Dim ond gwladwriaethau sofranaidd a thiriogaethau dibynnol sydd wedi eu cynnwys, felly mae'r ystadegau am wledydd Prydain (e.e. Cymru) wedi eu cynnwys yn rhai'r Deyrnas Unedig gan nad yw'r Cenhedloedd Unedig, ffynhonnell y wybodaeth, yn casglu ystadegau ar wahân.
