Australia is in the Southern Hemisphere so December to February are summer months and June to August are winter months. Data on vitamin D deficiency levels were collected throughout the year for the Australian National Health Measures Survey. This was then used to analyse the seasonal effects of vitamin D deficiency. Vitamin D deficiency levels for those who had their blood samples taken in summer were compared with those who had them taken in winter. The maps show the vitamin D deficiency by state between 2011 and 2012.
