Report Location <10 or 12 ng <20 ng
Arabi et al (2010) 9 Iran and Jordan 50%✻ ✻ 90%✻ ✻
Zhang et al (2013) 5 China ~ 37% ~ 72%
Web 2018 India - 56%
Cashman et al (2016) 8 EU countries (adults) 13% 40%
Mogire et al (2019) 6 African continent 18% 34%
Hilger et al (2014) 2 Global 7%✻ 37%✻
Herrick et al (2019) 7 USA 5% 18%

    ✻ % deficient globally is probably higher. - Appears that the population size was ignored - see reference #2 below

    ✻ ✻ Middle East: has dark skin and air conditioning - staying out ot extreme summer heat ==> colds in the sunner

It appears that Asia has far lower average vitamin D levels than Africa ( as well 3.7X more population)
