A traditionalism score was computed for white MIDUS Study participants based on the following items: endorses high moral standards; endorses religious values and institutions; expresses positive regard for parents; endorses strict child-rearing practices; values conventional propriety and a good reputation; opposes rebelliousness and unrestricted freedom of expression; condemns selfish disregard of others.
I divided the sample into low and high traditionalism groups and calculated the mean number of children for all ages 45 and over:
Mean number of children
High traditionalism 2.93
Low traditionalism 2.39*
Difference: 0.54 children
High traditionalism 2.88
Low traditionalism 2.58*
Difference: 0.30 children
* significantly lower than counterpart
Traditional white men average about one-half of a child more than their non-traditional counterparts. The gap is smaller for white women: 0.3 more kids. (All the means seem high. Respondents were asked to include step-children, adopted children, etc.)
The heritability of traditionalism is estimated to be 60 percent.
The country might inch in a more traditional direction, if current trends are sustained (over a very, very long time). (I'm assuming the trend is the same among our growing population of Hispanics and Asians).
