1

Estimated OLS models differ without constant based on Chow test (p<.05).

2

Estimated OLS models differ with constant based on Chow test (p<.05).

3

Chow tests not conducted because male and female models are specified differently.

W,F

Estimated coefficients differ by gender based on Chow test (p<.05) in work model (W), formal volunteering model (F).

Notes : Data shown for OLS models are regression coefficients with standard error in parentheses. Results for women’s informal volunteering are from a zero-truncated negative binomial model and show marginal effects with standard errors in parentheses. Reference categories are ages 45–49, not working for pay (in formal/informal volunteer models), not a formal volunteer (in paid work and informal volunteer models), not an informal volunteer (in paid work and formal volunteer models), no educational activities, less than a college degree, does not receive retirement income, does not receive SSI, does not receive SS, white, fair/poor health, no work disability, not married, no children under 18 in the household, not giving adult care, not providing care to nonresident children, 2003, and weekend interview.
