It’s the demographics.
Among the 50 states and the District of Columbia, Vermont ranks:
2nd highest proportion of non-Hispanic Whites (94.3%)[84][85]
2nd oldest median age[86]
41st highest proportion of Asians (1.3%)
49th highest proportion of Hispanics (1.5%)
48th highest proportion of Blacks (1.0%)
29th highest proportion of Native Americans (0.4%)
39th highest proportion of people of mixed race (1.7%)
28th highest proportion of males (49.2%)
24th highest proportion of females (50.8%)
Yup. You nailed it.
The elephant in the room no one will acknowledge........
All those flannel-clad lesbians are packin’!
I think you left out the most important demographic, about Vermont having the 2nd highest number of Massachusetts people in the nation...
And on a side note: if you're from Massachusetts, stay the hell out of Texas: we don't need folks like you here.
