"Among people aged 12 or older, past month binge alcohol use declined from 24.9 percent in 2015 to 23.9 percent in 2019 (Figure 8). Among current alcohol users aged 12 or older, however, past month binge alcohol use did not change significantly from 2015 to 2019 (48.2 percent in 2015 and 47.1 percent in 2019).²¹

"Aged 12 to 17
"Among adolescents aged 12 to 17, the percentage who were past month binge alcohol users declined from 5.8 percent (or 1.4 million adolescents) in 2015 to 4.9 percent (or 1.2 million adolescents) in 2019 (Figure 8 and 2019 DT 7.6). However, these estimates in 2019 were similar to those in 2016 to 2018.

"Aged 18 to 25
"Among young adults aged 18 to 25, the percentage who were past month binge alcohol users declined from 39.0 percent (or 13.6 million people) in 2015 to 34.3 percent (or 11.6 million people) in 2019 (Figure 8 and 2019 DT 7.12). These estimates in 2019 were lower than those in 2015 to 2017, but they were similar to those in 2018.

"Aged 26 or Older
"Among adults aged 26 or older, the percentage who were current binge drinkers remained stable between 2015 and 2019 (Figure 8). In 2019, 24.5 percent of adults aged 26 or older (or 53.1 million people) were binge alcohol users in the past month (2019 DT 7.15)."

Note: According to SAMHSA:
"In addition to asking about any alcohol use, NSDUH collected information on past month binge alcohol use and heavy alcohol use. Binge drinking for males was defined as drinking five or more drinks¹⁸ on the same occasion on at least 1 day in the past 30 days, which has remained unchanged from the threshold prior to 2015. Since 2015, binge alcohol use for females has been defined as drinking four or more drinks on the same occasion on at least 1 day in the past 30 days.¹⁹ This definition of binge alcohol use is consistent with federal definitions.²⁰ Heavy alcohol use was defined as binge drinking on 5 or more days in the past 30 days based on the thresholds described previously for males and females.

"Among the 139.7 million current alcohol users aged 12 or older in 2019, 65.8 million people (47.1 percent) were past month binge drinkers (Figure 6). Among past month binge drinkers, 16.0 million people (24.4 percent of current binge drinkers and 11.5 percent of current alcohol users) were past month heavy drinkers.²¹"
