A confidence interval (CI) describes the level of
uncertainty of an estimate and specifies the range in which the true value is
likely to fall. The State of Aging and Health in America online report
uses a 95% level of significance, which means that 95% of the time, the true
value falls within these boundaries.

When comparing
prevalence of variables across states or years, we recommend the use of
confidence intervals. If the confidence intervals overlap, the difference is
not statistically significant.
