NOTE: HRS 67 + sample requires (1) age ≥ 67 years and (2) responded to HRS interview. HRS claims–linked sample additionally requires continuous FFS enrollment for at least 2 years. The reported percentages are weighted using wave-specific HRS sampling weights to adjust for survey design. P values indicate the level of statistical difference in characteristics between HRS 67 + sample and HRS claims–linked sample.
