Outdoor air pollution kills more than a million people every year globally. This map by the World Health Organization (WHO) shows the number of deaths caused by urban air pollution (UAP) per 1,000 people.
Based on data for 2002, the highest number of deaths caused by UAP occurred in Argentina and Uruguay in the Americas; Ukraine, Romania and Bulgaria in Europe; Iraq, Turkey, and Azerbaijan in Asia.
Cancer affects both women and men globally. However, cancer death rates are different for each gender, as can be seen in the two maps displayed in this article.
We find the highest cancer death rates for women (126 or more per 100,000 population) in Mongolia, Denmark, Albania, Macedonia, Uganda, and Honduras.
The cancer death rate for men is the highest (150 per 100,000 people) in most parts of the world, compared to women. Countries with high death rates for males include most European countries, Middle Eastern nations, Russia, Mongolia, Kazakhstan, China, Japan, South and North Korea, Turkey, South Africa, Argentina, Uruguay, and Cuba. Other countries with high death rates for males (126 or above per 100,000 people) include the United States, Canada, Brazil, and Australia.
We can only speculate about the factor behind this disparity in numbers of cancer death rates for men and women worldwide.

Countries with the largest number of physicians per 1,000 population include: San Marino (47.35), Cuba (6.72), Greece (6.17), Monaco (5.81) and Belarus (5.18).
Countries with the smallest number of doctors per 1,000 people include: Colombia, Nicaragua, Haiti, Liberia, Niger, sierra Leone, Rwanda, Ethiopia, Yemen, Afghanistan, Myanmar, Thailand, Cambodia, Indonesia, Papua New Guinea, etc.
According to a 2010 infographic by Information is Beautiful, people inhabiting in the Northern hemisphere, more precisely above latitude 42°N, are not getting enough UVB light from sunlight to make vitamin D in the skin during winter season.
In the UK, 50% of the population has insufficient levels of vitamin D, while 16% of the population is severely deficient. In the United States, 77% of the population has insufficient levels of vitamin D, while 6% of the population is severely deficient. Within the U.S., the groups more affected by insufficient levels of vitamin D are Non-Hispanic blacks (98%) and Mexican Americans (90%).
To try compensate for the lack of UVB light in winter time and the consequent low vitamin D levels, consumers have turned to the vitamin D industry, an industry that is worth $460 million, as of 2009, in the U.S. alone.
