Sample characteristics
The present sample comprised 14,687 older adults: 3059 (20.8%) living alone, 6644 (45.3%) living with their spouse, and 4984 (33.9%) living with their family (Table
1). There were significant differences in the sociodemographic characteristics of the three groups (
p < .001). Among older adults living alone, 692 (4.7%) were male and 2367 (16.1%) were female. Among those living with their spouse, 3786 (25.8%) were male and 2858 (19.4%) were female. Among those living with their family, 1845 (12.6%) were male and 3139 (21.4%) were female. The average age was 74.86 ± 6.45 years, 72.47 ± 5.50 years, and 73.56 ± 6.75 years for older adults living alone, those living with their spouse, and those living with their family, respectively (
p < .001). Although the educational category of elementary school graduates had the highest percentage in all three groups, there was a significant difference in educational level between the three groups (p < .001). Regarding marital status, 2360 older adults living alone were widowed and 2736 older adults living with their family were married, with these categories having the highest percentages in these two living arrangements (p < .001). Regarding employment status, in all three groups, the highest percentage was observed for unemployment. In all three groups, the highest percentage was observed for those not eligible for basic livelihood rights. Regarding the monthly average income, the highest proportion was 500,000 to 990,000 Korean won for older adults living alone, 1,000,000 to 1,990,000 Korean won for those living with their spouse, and over 2,000,000 Korean won for those living with their family (
p < .001).

Comparison of variables between the three groups
The results of the comparisons between depressive symptoms, present health status, satisfaction with socio-physical environment, social support networks, participation in social activities, and happiness in older adults living alone, those living with their spouse, and those living with their family have been presented in Table
2 and Table
3. Significant differences between the three living arrangements groups were observed for happiness, depressive symptoms and present health status (
p < .001). In terms of satisfaction with the socio-physical environment, the three groups differed significantly in terms of trust in neighbors (
p = .001), help from neighbors (
p < .001), neighborhood safety level (
p = .009), condition of public transportation (
p = .007), and condition of medical facilities (
p = .002). Regarding social support networks, the three groups differed significantly in the frequency of contact with family, neighbors, and friends (
p < .001). Finally, with reference to social activities, the three groups differed significantly in their participation in religious, belonging to communities, leisure, and charity activities (
p < .001).

Logistic regression analyses
The results for the logistic regression of the general characteristics; depressive symptoms; present health status; satisfaction with socio-physical environment; social support networks; participation in social activities; and happiness of older adults living alone, those living with their spouse, and those living with their family are presented in Table
4. The model was constructed with happiness as the dependent variable; sociodemographic characteristics, depressive symptoms, present health status, satisfaction with socio-physical environment, social support networks, and participation in social activities were independent variables. Separate models were derived for each of the three living arrangements groups of older adults. The models for older adults living alone (− 2 Log L = 3100.816, chi-square = 643.169,
p < .001), those living with their spouse (− 2 Log L = 6275.436, chi-square = 1140.529,
p < .001), and those living with their family (− 2 Log L = 4914.185, chi-square = 842.456,
p < .001) met the convergence criterion for logistic regression.

Significant factors influencing happiness in the three living arrangement groups were as follows. Among older adults living alone, females were 1.39 times more likely to be happy than were males (odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.08–1.78). As compared to participants with a college graduate degree or higher, happiness was 37% lower in middle school graduates (OR = 0.63, 95% CI = 0.42–0.95). Further, happiness was 26% lower in older adults who were employed (OR = 0.74, 95% CI = 0.59–0.92) than in unemployed older adults living alone, while happiness was 32% lower in those who were eligible for basic livelihood rights (OR = 0.68, 95% CI = 0.53–0.88) than in those not eligible for basic livelihood rights. Happiness was 52% lower in those with a monthly income of less than 500,000 won (OR = 0.48, 95% CI = 0.32–0.72) than for those with a monthly income of over 2,000,000 Korean won. Further, happiness scores decreased with an increase in depressive symptoms (OR = 0.87, 95% CI = 0.85–0.90), and increased with an increase in the present health status level (OR = 1.21, 95% CI = 1.15–1.28). With reference to social support networks, those who trusted their neighbors were 1.45 times more likely to be happy than those who did not (OR = 1.45, 95% CI = 1.16–1.82). Further, happiness was lower in those who had contact with their family only once a month (OR = 0.70, 95% CI = 0.51–0.95) or two to three times a week (OR = 0.75, 95% CI = 0.57–0.99), respectively, than those who had contact with their family four or more times a week. Similarly, happiness was 38% lower in those who had contact with neighbors only once a week (OR = 0.62, 95% CI = 0.42–0.93) than those who had contact with neighbors four or more times a week. Happiness was 1.44 times higher in those who had contact with friends two to three times a week (OR = 1.44, 95% CI = 1.05–1.96) than those who had contact with friends four or more times a week. With reference to participation in social activities, those who participated regularly in religious activities were 1.49 times more likely to be happy than those who did not (OR = 1.49, 95% CI = 1.24–1.79). Further, those who participated regularly in belonging to communities were 1.25 times more likely to be happy than those who did not (OR = 1.25, 95% CI = 1.03–1.52), and those who participated regularly in leisure activities were 1.38 times more likely to be happy than those who did not (OR = 1.38, 95% CI = 1.05–1.80).
Among older adults living with their spouse, as age increased, the probability of being happy increased (OR = 1.02, 95% CI = 1.01–1.03). As compared to those who were college graduates or higher, all those with an educational level of below high school graduation were less likely to be happy (OR = 0.73, 95% CI = 0.58–0.92). As compared to those with a monthly income of over 2,000,000 Korean won, those with a monthly income of below 1,990,000 Korean won were less likely to be happy (OR = 0.64, 95% CI = 0.54–0.76). Further, while happiness decreased with an increase in depressive symptoms (OR = 0.87, 95% CI = 0.85–0.89), it increased with an increase in present health status level (OR = 1.26, 95% CI = 1.21–1.31). Those who trusted their neighbors were 1.32 times more likely to be happy than those who did not (OR = 1.32, 95% CI = 1.13–1.54).
