(1)

Among all the 8,268 respondents in the full sample, all of them have reported information on age and urban/rural residence, 8,266 on gender and education, 6,081 on relative living standard, 8,012 on household expenditure, 7,401 on either long or near vision capacity, 7,396 on long vision capacity, 7,398 on near vision capacity, 7,430 on hearing capacity, 7,377 on dual sensory loss, 7,399 on unmet needs for glasses, 7,386 on unmet needs for hearing aids, and 7,431 on social activities.

(2)

Full sample (8,268 respondents) is used for descriptive analysis, while restricted sample (7,212) is used to check associations between hearing/vision loss and social activities.

(3)

Weighted and unweighted proportions (%) are calculated based on respondents in full or restricted samples with reported information on each of the variables. For instance, in the full sample, 8,266 have reported gender information, and the proportion of males and females are calculated based on 8,266 instead of 8,268 respondents.
