Since the release of the 2018 wave of the General Social Survey, the big story has been about the sex drought: rising numbers of Americans, especially young men, are eschewing sex altogether. These data have been puzzled over by the Washington Post, Washington Free Beacon, and the blogger Spotted Toad.
Every time the GSS sex data are discussed there are always questions over accuracy. Like, are people willing to recount their amorous adventures to perfect strangers? I’ve analyzed these data to look at cohort trends in promiscuity, the effects of premarital promiscuity on marital happiness, and the demographics of promiscuous America, so I have a vested interest in their accuracy.
One way to get a sense of the validity of the GSS sex data is to look at different variables measuring celibacy. As far as I can tell, the aforementioned estimates of the sex drought are based on the SEXFREQ variable, which looks like this:
SEXFREQ FREQUENCY OF SEX DURING LAST YEAR
- About how often did you have sex during the last 12 months?
-1 IAP [Question not asked]
0 NOT AT ALL
1 ONCE OR TWICE
2 ONCE A MONTH
3 2-3 TIMES A MONTH
5 2-3 PER WEEK
6 4+ PER WEEK
8 DK [Don’t Know]
9 NA [No Answer]
But there’s another option: PARTNERS, which records how many sex partners a respondent has had in the previous 12 months. Our faith in the GSS sex data should increase if the two variables produce the same estimates of the growth in celibate Americans. Here’s what the data look like:
The two variables produce largely similar results. Indeed, PARTNERS seems preferable because it has two more years of data available. PARTNERS was in the 1988 survey, while SEXFREQ didn’t start until 1989. Moreover, the 2012 SEXFREQ data are unusable for measuring abstinence because the base population is different.
SEXFREQ does seem to under-count celibacy in recent years (alternately, PARTNERS exaggerates it). But the disparity disappears if the analysis is limited to adults ages 18-34, which several writers have suggested is the epicenter of our celibacy epidemic.
Both variables confirm that the rise in celibacy is strongest among younger Americans.
Why does PARTNERS underperform when looking at Americans of all ages, but not younger adults? It probably has to do with measurement error. I’ve noted elsewhere that 7 percent of married women and 9 percent of married men claim zero lifetime sexual partners. Presumably, these respondents misinterpreted the survey question as inquiring about former sex partners. Presumably also this misinterpretation is less likely among unmarried survey respondents—and Americans in the 18-34 age range are less likely to be married in recent years. If this hunch is correct, it would explain why the PARTNERS variable only under-performs SEXFREQ in the analysis of American adults of all ages.
But you don’t have to believe me on the accuracy of the GSS sex data. Take it from sociologist Edward Laumann and his colleagues, who in the 1990s collected the highest quality national data on sex ever. They went to unusual lengths to ensure accurate measurement, then compared their data to the General Social Survey (p. 33). Here’s how their data stacked up against the GSS.
As is apparent, the GSS sex data fare well against Laumann’s NHSLS. Maybe recall bias has changed a bit since the early 1990s, but I doubt it. There will always be some measurement error in sex data, but the GSS data seem to be holding their own.
