We suggest caution in interpreting our observations comparing birth cohorts stratified by age groups. The oldest baby boomers in our study were age 68 in 2014, the endpoint of our study; therefore, the comparison, which was based on overlapping confidence intervals, was necessarily limited by age. Our observations on birth cohorts stratified by age groups were secondary to our main analysis, which was a study of trends in drinking among individuals ages 60+ across the NHIS 1997–2014 survey years. We performed these analyses because one of the factors contributing to trends varying over time by age group is the composition of birth cohorts. We thought it important to report these data given that baby boomers will be driving future population expansion. The baby boom cohort encompasses the years 1946–1964. In previous studies, Keyes and Miech (2013) suggest a rise in log odds of binge drinking from earlier (1910–1914) through more recent (1950–1954) birth cohorts. Kerr et al. (2009) reported that for women only, those born between 1956 and 1960 drank more heavily than cohorts born earlier. Taken together, the evidence
