Here are some studies investigating the economic costs of vitamin D deficiency around the world:
Conclusion: This study calculated that the average lifetime cost of caring for and supporting a single individual with an autism spectrum disorder is $1.4 to $2.4 million (depending on the level of disability), due to special education costs, parental productivity losses, and supportive living accommodation costs during adulthood. This is five to ten times higher than the often cited $240,000 average cost of raising a normal child for 17 years. Autism has been linked to vitamin D-deficiency during fetal development.

An Estimate of the Economic Burden and Premature Deaths Due to Vitamin D Deficiency in Canada (2010)
Conclusion: This study investigating the economic costs of vitamin D deficiency estimates that by increasing the average vitamin D level among the Canadian population to 42 ng/ml, annual deaths could be reduced by 37,000 (16%) and the economic burden could be reduced by 6.9% ($14 billion).
Estimated Benefit of Increased Vitamin D Status in Reducing the Economic Burden of Disease in Western Europe (2009)
Conclusion: This study calculated that by achieving an average vitamin D level of 40 ng/ml among the European population, healthcare spending in Europe could be reduced by 187 billion Euros per year. This could easily be achieve on the individual level by supplementing and/or increasing healthy sun exposure.
Conclusion: This study calculated that the total average lifetime cost of supporting a single autistic person in the U.S. is $3.2 million and all U.S. cases combined could cost more than $35 billion total. This is thirteen times higher than the often cited $240,000 average cost of raising a normal child for 17 years. Autism has been linked to vitamin D-deficiency during fetal development.

Comparisons of Estimated Economic Burdens Due to Insufficient Solar Ultraviolet Irradiance and Vitamin D and Excess Solar UV Irradiance for the United States (2005)
Conclusion: In this study, world-leading vitamin D experts Dr. William Grant, Dr. Cedric Garland, and Dr. Michael Holick calculated that the U.S. economic burden stemming from healthcare costs due to ailments caused by vitamin D deficiency in 2004 was $40-$56 billion dollars. Vitamin D deficiency has been linked to many forms of cancer, autoimmune disorders cardiovascular disease, colds/flus, skeletal diseases, injuries in the elderly, depression, chronic fatigue, type 2 diabetes, and much more.
