What percentage of humans reproduce?

Published by: wktd 2009-01-08

Suitable definitions of "humans": - people in the US - people in industrialized nations Suitable definitions of "reproduce" - have children right now - have had children at one point in their life - are likely to have children based on some extrapolation Note: children-per-woman statistics are all over the place, but not acceptable. The hardest part of answering this question is the fact that most statistics-gatherers care about the *number* of children, not the *number of people who have children*. You can't compute one from the other since the former gives greater weight to people with lots of kids, and the latter does not.

Thank you for the tip. -juggler

Rock on! Exactly what I wanted (and more).

Hello. According to research cited by the American Association of University Professors, 87% of women and 81% of men reproduce. "Eighty-seven percent of women become parents during their working lives. 3 ... 3. Jane Waldfogel, "The Effect of Children on Women’s Wages," American Sociological Review 62 (1997): 209. Similarly, 81 percent of men become fathers at some point in their lives. See Nancy E. Dowd, Redefining Fatherhood (New York: New York University Press, 2000)" source: American Association of University Professors http://www.aaup.org/statements/REPORTS/re01fam.htm Similar percentages are reported by the US Department of Health & Human Services Percentage of adults ages 45 and older who have ever had a biological child (2000) Males: 84% Females: 86% source: US Department of Health & Human Services "Charting Parenthood: A Statistical Portrait of Fathers and Mothers in America" http://fatherhood.hhs.gov/charting02/introduction.htm#Who Of course, these percentages do not include the adults ages 45 and older who have not yet had their first child but eventually do so. However, against the population as a whole, such people aren't going to be statistically significant. The number of births to women 45 to 54 years old was 4,565 in 2000. source: Associated Press http://www.myrtlebeachonline.com/mld/sunnews/2642279.htm 4,565 births represents only a tiny percentage of the total births in the U.S., and it is even less significant for purposes of this question when you consider that many of those mothers were not first-time mothers. And while men older than 45 can and do father children, the percentage of men who become first-time fathers at 45 or older is very small. Also see: ABC News "Eighty percent of Americans today become parents." http://abcnews.go.com/sections/living/Healthology/women_nochildren1020603.html ---------- Here are various related statistics from countries other than the U.S.: "Australia... For women born more recently childlessness appears to be on the rise and on current rates is expected to reach 28%." Australian Demographic Statistics Special Article - Lifetime Childlessness (Sep, 1999) http://www.abs.gov.au/Ausstats/abs@.nsf/Lookup/1DECC52B47FC8E26CA2569DE002139C1 "Only 10 percent of French women will not have children, which is indeed low, compared with countries like Germany, where it reaches 17 percent. " source: info-france-usa.org http://www.info-france-usa.org/publi/nff/0201/soc.htm "Canadian research suggests that around 11 percent of men will not have children." source: Teendads.org.za http://www.teendads.org.nz/fatherandchild/fcarchives/issue08/blended.html -------------- search strategy: percent "become parents" "some point" "men will have children" "women will have children" "americans will have children" percent "ever have children" "birth to at least one child" I hope this helps. If anything is unclear, please let me know via the "request clarification" feature. Thanks.
