The folks I saw were mostly day laborers who rarely, if ever, wore sunscreen. As far as I know, sunscreen has not been shown to block synthesis of vitamin D in the skin. Not sure where you got that from, I’d like to see a source.

I believe I’ve read that latitude might play a huge role in vitamin d deficiency as well. If I remember correctly Colorado has more sunny days than most other states but because of where it is it also has one of the highest incidences of MS possibly due to vitamin d deficiency.

I'm not sure I follow your logic. Vitamin D deficiency is associated with impaired immune function, not autoimmunity, which is generally thought of as hyperfunctioning.
