A study was done in 2012 to break down the demographics of those who purchase lottery tickets in the United States. Men were found to play the lottery much more frequently than women, with 18.7 days per year for men, compared to 11.3 days per year for women. A whopping 79% of those between the ages of 20 and 39 play the lottery in any given year, while the number decreases to 66% for those ages 40-69, and 45% for people aged 70 and over. Native Americans were found to have the highest average when it comes to days of gambling, with the average reaching 25 days each year. They also, along with Caucasians, had the highest percentage of people— over 50%— who had played the lottery in the previous year. Amongst the lowest one-fifth, based on socioeconomic status, 61% of people had gambled throughout the course of the past year, with an average of 26.1 days. For the top three levels of socioeconomic status, the percentage dropped to just 42%, with 10 days of gambling.
