Two things: the somewhat random-looking picture above is from The Moon Is Blue, a film that’s the first known reference to the ‘dating rule’ discussed here. Secondly, I don’t make any judgement about the validity of the ‘dating rule’ – you might find it a useful rule of thumb or a ludicrous restriction; I find it a nice thing to do some algebra on. There is a so-called rule about dating: the youngest age you are supposed to date is half your age plus seven. Why would we want to do this? Well, it means we can work out some other implications of the rule. For instance, you might want to know what the oldest age you could reasonably date would be.
half your age plus seven
As my mom used to tell me at bedtime when I was a little girl: “No amount of money is worth being bounced on a decrepit old dude’s arthritic knee. But I’m sure she wanted to. The tradition of math nerds using their skills to figure out their chances of getting laid by a hot girl is a long, proud one as well: John Nash famously came up with game theory as a Princeton undergrad trying to figure out how to guarantee that him and all his buddies score with girls at a bar.
Now a website called SugarDaddie. It’s for sugar daddies , has come up with a calculation inspired by Hugh Hefner’s 86th birthday.

Age disparity in sexual relationships is the difference in ages of individuals in sexual relationships. Concepts of these relationships, including what defines an age disparity, have developed over time and vary among societies. Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross-culturally. There are also social theories for age differences in relationships as well as suggested reasons for ‘alternative’ age-hypogamous relationships.
Age-disparity relationships have been documented for most of recorded history and have been regarded with a wide range of attitudes dependent on sociocultural norms and legal systems. Data in Australia  and United Kingdom  show an almost identical pattern. Relationships with age disparity of all kinds have been observed with both men and women as the older or younger partner.
In various cultures, older men and younger women often seek one another for sexual or marital relationships. Most men marry women younger than they are; with the difference being between two and three years in Spain,  the UK reporting the difference to be on average about three years, and the US, two and a half. Another study also showed a higher divorce rate as the age difference rose for when either the woman was older or the man was older.
In August , Michael Dunn of the University of Wales Institute, Cardiff completed and released the results of a study on age disparity in dating. Dunn concluded that “Not once across all ages and countries

Younger older relationships can bring with them many questions. Is the younger person subconsciously seeking out a parental figure? Is the older person just looking for someone younger and aesthetically pleasing? Or perhaps, in some instances, it’s merely a case of people of different ages falling for one another despite the age gap. The very question of what is considered too young-or old-has been pondered by the French, who developed a useful formula called “Half Your Age Plus Seven?
For example, a year old can date anyone from 22 to 46, according to the formula. To get 22, you divide 30 in half, leaving you with 15 remaining, and then add seven more to arrive at

Age disparity in sexual relationships is the difference in ages of individuals in sexual Although the “cougar” theme, in which older women date much younger men, is often used to determine whether an age difference is socially acceptable. as a formula to calculate ideal age for the bride, instead of a lower limit for the.
To compare the accuracy of a new formula to one developed in and still in common use and to develop and compare racial and ethnic—specific and racial and ethnic—neutral formulas. Women with a certain last menstrual period confirmed by first-trimester ultrasonogram had longitudinal fetal measurements by credentialed study ultrasonographers blinded to the gestational age at their five follow-up visits. Regression analyses were performed with linear mixed models to develop gestational age estimating formulas.
Repeated cross-validation was used for validation. The new formula performed significantly better than a formula developed in with an estimation error of Racial and ethnic—specific formulas did not outperform the racial and ethnic—neutral formula. The NICHD gestational age estimation formula is associated with smaller errors than a well-established historical formula.
Racial and ethnic—specific formulas are not superior to a racial—ethnic neutral one. Accurate gestational dating is imperative for optimal maternal and neonatal outcomes. The recent performance and completion of the Eunice Kennedy Shriver National Institute of Child Health and Human Development NICHD Fetal Growth Studies provides a unique opportunity to readdress the issue of gestational age estimation in a larger and diverse cohort, one which included a cohort of women of four different racial—ethnic groups, conditions that were optimal for fetal growth, a standardized ultrasound protocol and extensive training and quality control of images and measurements.
Since there is no consensus in the obstetric community on whether racial and ethnic—specific formulas are superior to racial and ethnic—neutral formulas, the NICHD Fetal Growth Studies provide this opportunity as well. Our objectives were to develop a gestational age estimation model using ultrasound fetal parameters in women who participated in the NICHD Fetal Growth Studies, to compare this formula to one in common use, 4 and to assess the accuracy of racial and ethnic—specific formulas.
The NICHD Fetal Growth Studies-Singletons was a prospective cohort study that recruited women of four self-reported racial or ethnic groups non-Hispanic black, Hispanic, non-Hispanic white and Asian , who had low-risk pregnancies with optimal conditions for fetal growth. To be included, women had to have a certain last menstrual period and a first trimester ultrasound that confirmed their pregnancy dating.
A mathematical theory says the perfect age to get married is 26 — here’s why
Megan is upset because she is apparently older than 26, and among people who marry, half do so below The intuitive conclusion is that the number of potential partners is decreasing as time goes on. The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years. As the graph shows, there is a lower limit and an upper limit.
Not everyone will agree with the results of this formula – and it is not to figure out if your dating age range is “acceptable” by the aforementioned standard.
Subscribe To Our Newsletter! According to this rule, it would not be creepy for a 30 year old to date a 22 year-old, but an 18 year-old would be off-limits. Although this is a fun rule of thumb, what does research say about age preferences for potential mates? From an evolutionary perspective , it makes sense for women to prefer mates with resources and to like partners who are more established, both of which are more likely in older partners.
Men, in contrast, are hypothesized to be most attracted to women in their reproductive prime, which tends to be when they are younger. Data from Kenrick and Keefe 1 support these predictions. Younger men tend to prefer women a few years younger or older than themselves; but as they get older, they increasingly prefer younger women relative to their own age. It turns out that, on average, women tend to be married to men a few years older than themselves years.

Mariella Frostrup says a father’s anger at his daughter’s relationship is understandable – but may be to do with his own unresolved past.
Going by the popular formula, year-olds should not be with anyone younger than 22, year-olds should go for people who are at least 27, and so on. But how many people follow this rule? First, here is a graph of the acceptable dating range for each age using the half-plus-seven rule, illustrated by data blogger Randal Olson:. The biggest takeaway from this graph is that, for the most part, OkCupid men stay just barely within the range prescribed by the half-plus-seven rule.
What does this mean? Obviously, the so-called “zone of non-creepiness” is not a hard-and-fast rule; when you are adults of consenting age, no one’s going to punish you for violating this arbitrary guideline. Still, it’s worth noting that at every age level, “men aren’t even close to reaching the upper bound of the zone of non-creepiness,” as Olson points out. Of course, it’s hard to tell from these graphs how serious of a relationship these men are looking for.
As with all things, the half-plus-seven rule is better used as a rule of thumb than a strict law. But even so, if you keep skirting the accepted minimum, you might consider widening the pool to older potential partners. And if you have trouble with basic arithmetic, here is a handy calculator to figure it out for you. By Eileen Shim.
