David P. Schmitt of Bradley University compared the sociosexuality of no fewer than 48 countries in a scholarly paper entitled Sociosexuality from Argentina to Zimbabwe: A 48 nation study of sex, culture, and strategies of human mating. A sociosexual orientation is a tendency toward either unrestricted casual sex or toward stable committed relationships. Dave must have had a blast gathering data. (Was it a taxpayer-funded grant?) Keep in mind the results have little to do with pay-for-sex hot spots (Amsterdam, for instance), which often exist in places in which much more culturally conservative attitudes prevail generally. Nearly all of the differences among countries are in female attitudes; men don’t vary much place to place, and to the extent they do it is in the opposite direction to women.
There are some surprises. The supposedly reserved Brits score far higher than Americans who, amazingly, edge out the supposedly amorous French.
Schmitt’s method for deriving the actual numbers is complex. I suggest consulting the study if you are interested (it is dry and in PhD-ese, but informative), but the bottom-line results are below. High scores lean casual.
New Zealand 47.69
Czech Rep. 37.52
Congo, DR 32.43
Hong Kong 22.90
South Korea 22.21
The Finns, huh? Who knew?
