82,966 observations were nested within 33,072 persons. Objective social class was standardized per year across all subjects. The reference value for year was 2005. OR = Odds Ratio. b = estimated coefficient of the multilevel ordered probit model. Gender: 1 = male; 2 = female.

a Multilevel logistic regression model (0 = nonvolunteer; 1 = volunteer).

b 0 = never, 3 = every week.

** p < .01.
