for 18–29 year olds and increased strongly with age. Average annual increases were 1.1% for 30–49 year olds, 2.7% for ages 50–64, and 3.4% for individuals aged 65 and over. Differences in the rate of increase in binge drinking prevalence by education was relatively small, although the increase for those with education beyond high school was significantly larger than that for those without a high school education for whom there was no increase (approximately 1.0% annually for post-secondary group vs. 0.0% for less than high-school, z=4.7, p<.001). Simulated trend lines using reference data from the NSDUH and calculated based on the meta-analytic trend estimates are plotted in Figure 5.
