Mortality risk ratios (95% confidence intervals) by parental birth area for people born and residing in western Finland

Variable	Risk ratio		Wald(d.f.)	p-value
Parents' birth area (or ethnicity)
Both from western Finland	Reference		45.44(2)	< 0.001
One or both from eastern Finland	1.21	(1.04 to 1.41)
Swedish speaker	0.66	(0.56 to 0.78)
