Sources

Verification note. Wording and percentages for the TRANSVAR self-identification item copied directly from the topline PDF. This is the only transgender-related item in this wave: KFF's Health Tracking Poll carries a trans self-identification screener in its demographic block but, in the waves checked, asks no attitude questions about transgender people or policy. Margin of error was not pulled from this PDF.

Figures below are transcribed from these documents. Where they disagree with the source, the source governs.

Questions asked (1)

Contact & populationforced choicein a trend series
share of U.S. adults who describe themselves as trans or transgender

Asked in the demographic block, immediately after RGENDER ('(IF PHONE: Just to confirm,) Do you describe yourself as a man, a woman, or in some other way?') and before the LGBQ sexual-orientation item

Do you currently describe yourself as trans or transgender?

No
98%
Yes
2%

Wording notes: two-step gender measure: current gender description asked first, trans status second | rounded to whole percentages, so the published value carries substantial rounding error at a base rate of 1-2 percent | combined with the LGBQ item into KFF's LGBT_Total / LGBTQ_TOT summary variable

neutral — standard two-step self-identification screener; the phone-mode 'just to confirm' preface on the preceding gender item is a mode accommodation rather than a cue
