Notes: Percentages are weighted statistics; sample sizes may vary due to missing values; data may not add to 100% due to rounding; HRS included persons age 51 and older at time 1; MHAS included 52 years and older at time 1; HRS and MHAS data includes only community-dwelling populations. Statistical comparisons based on unweighted data. Statistical test of the difference across categories for each variable within each country is reflected by embedded asterisks: ^∗𝑃<.001, ^∗∗𝑃<.05, ^∗∗∗𝑃<.1. Statistical test of the difference between the two countries is reported in the final column (𝑃 value). Difference in education is not tested between countries because of the difference in educational categories.
