TABLE 1—

Prevalence of Exposure to 4 or More Adverse Childhood Experiences (ACEs) by Generation: Behavioral Risk Factor Surveillance System, United States, 2019

	Generation, % (95% CI)				P
Baby Boomers	Generation X	Millennials	Generation Z
ACEs					< .001
≥ 4	14.69 (13.92, 15.46)	22.31* (21.06, 23.56)	26.77* (25.21, 28.33)	26.78* (23.64, 29.92)
< 4	85.31 (84.54, 86.08)	77.69* (76.44, 78.94)	73.23* (71.67, 74.79)	73.22* (70.08, 76.36)

Note. CI = confidence interval. Weighted percentage of people with ≥ 4 ACEs in 2019 for baby boomers (1946–1964), Generation X (1965–1980), millennials (1981–1996), and Generation Z (1997–2001). Percentages are weighted using the design variables for the 2019 Behavioral Risk Factor Surveillance System. The P values are for the goodness-of-fit χ² test for each ACE.

*Significantly different from baby boomers at P < .05.
