In 1964, Ford published data on average age of cessation of breastfeeding for 64 “traditional” cultures.
Ford’s data came from anthropological research by various anthropologists in 64 “traditional” societies around the world, prior to 1945.
, that there is a worldwide average duration for breastfeeding. .” Lawrence does not provide any citation for this figure in her book, and there are no ethnographic data to support the 4.2 years figure, neither for the modern world, nor for any time in the near or distant past.
She writes: “The average time of complete cessation [of breastfeeding] worldwide is 4.2 years.” (Lawrence 192). In addition to the lack of ethnographic evidence, there are other problems with this claim.
In the ethnographic literature there are many references to societies where may be nursed that long, and even up to the age of 12 or 15 years, but the average in those societies is still between two and four years.
There are also ethnographic references to cultures (or sub-cultures, in the United States) where children are allowed to nurse as long as they like, and individual children may nurse for 8‑10 years, but again, the vast majority of children in child-led weaning situations stop breastfeeding voluntarily between three and four years of age, so the average for those societies continues to be less than 4.2 years.
Men, in contrast, are hypothesized to be most attracted to women in their reproductive prime, which tends to be when they are younger. Women’s preferences, on the other hand, hold relatively constant across their lives, not going more than a few years below their own age (extra-credit if you can identify the "cougar zone" in this figure), but women remain keen on men up to 10 years older than themselves. However, younger men (i.e., in their 20’s) tend to be married to someone of a similar age, but as they get older their wives get younger.
Thus current evidence does not support globally synchronous periods of anomalous cold or warmth over this interval, and the conventional terms of "Little Ice Age" and "Medieval Warm Period" appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries....
This 4.2 year figure is widely cited by numerous groups, including La Leche League members, lactation consultants, and parents. In order for 4.2 years to be the “true” average, there would have to be many many societies that nursed their children for an average of more than 4.2 years, in order to offset the many societies that nursed their children for an average of less than 4.2 years ‑‑ to balance out and come up with an average of 4.2.
It turns up again and again on Internet forums, sometimes referenced to Lawrence, sometimes just as “I heard somewhere that. The ethnographic literature provides no documentation for any society where the average age of weaning is as long as five or six years, which would be necessary to balance out the many societies with averages less than four years.
It’s like asking what’s the average income in the US – the number of unemployed will totally skew the numbers (not to mention the throngs of millionaires).
If you want a better gauge of where you fit in, then you should be looking at the median credit score.
