Similar results were also found after analyzing World Value Survey data sets of 33
democratic countries from 1991 to 1993 (Curtis, Baer, & Grabb, 2001). Findings suggest
that cross national variance in association involvement is a function of economic
development, religious composition, democracy history, and type of prevailing policy in the
different nations. Rates of voluntary memberships and activities were typically high in
countries with high levels of economic development, that are predominantly Christian
(particularly protestant), that hold a prolonged democratic history, and that present a social
democratic or liberal democratic political system.
