On October 20, 2010, the United Nations first celebrated World Statistics Day. Statistics is the collection and analysis of sets of numbers. 
 
Statisticians compile accurate data from reliable sources. They create valuable, objective information for fields as varied as sports, economics, transportation, and health care.
 
Statistics combines elements of both mathematics and social science. Statisticians may measure the number of people who visit certain websites, how many political candidates are women, trends in the stock market, rates of deforestation, or patterns in disease and use of health-care services.
