Four central constructs of the post-modern perspective are extended an
d tested using secondary analysis of Census data and the NORC General
Social Survey: 1972-94 data sets. The modified postmodern themes of: (
1) the decline of a single universal family organizational standard, a
nd (2) growing cultural diversity, which is seen as legitimate-diversi
ty which is increasingly based upon affectivity and achievement emanat
ing from an emphases on relationship cooperation, friendship, individu
al choice and expressive communications, were supported by examining c
hanges in American family structure, attitudes toward such structural
changes, and changing attitudes toward marital and family patterns ove
r the last quarter century. However, little support was found for the
greater use of and reliance on, (3) the mass media. Mixed results were
found on the fourth construct, greater variance in, and/or loss of, p
ersonal happiness or personal or family life satisfaction. Possible ex
planations for these findings are discussed. Given the growing importa
nce and acceptance of organizational and cultural diversity, future st
udies of family structure and processes may profit from move narrowly
defined localized and pragmatic parameters of finely delimited social
aggregates. Such studies are more consistent with the realities of con
temporary American social organization and cultural values of family l
ife, the behaviors and attitudes of Americans, and the modified post-m
odern perspective.
