Marriages and sexual relationships between first cousins are stigmatized as incest in some cultures, but tolerated in much of the world. Currently, 24 [[US states]] prohibit marriages between first cousins, and another seven permit them only under special circumstances.<ref>Joanna Grossman, [https://supreme.findlaw.com/legal-commentary/should-the-law-be-kinder-to-kissin-cousins.html Should the law be kinder to kissin' cousins?]</ref>

First- and second-cousin marriages are rare in Western Europe, North America, and Oceania, accounting for less than 1% of marriages, but reach 9% in South America, East Asia, and South Europe, and about 50% in regions of the Middle East, North Africa, and South Asia.<ref>{{cite journal |doi=10.1016/j.paed.2008.02.008 |title=Consanguinity and child health |url=http://www.channel4.com/microsites/D/Dispatches/when_cousins_marry/cousins_10.pdf |year=2008 |last1=Saggar |first1=A |last2=Bittles |first2=A |journal=Paediatrics and Child Health |volume=18 |issue=5 |pages=244–249}}</ref> Communities such as the Dhond and the [[Bhittani]] of Pakistan clearly prefer marriages between cousins due to the belief they ensure purity of the descent line, provide intimate knowledge of the spouses, and ensure that [[Property|patrimony]] will not pass into the hands of "outsiders".<ref>{{Cite book |title=Encyclopedia of Women & Islamic Cultures: Family, Body, Sexuality and Health |first1=Suad |last1=Joseph |author-link=Suad Joseph |first2=Afsaneh |last2=Najmabadi |author2-link=Afsaneh Najmabadi |publisher=Brill |year=2003 |isbn=978-90-04-12819-4 |page=261 |url=https://books.google.com/books?id=bzXzWgVajnQC}}</ref> [[Parallel and cross cousins|Cross-cousin]] marriages are preferred among the [[Yanomami]] of Brazilian Amazonia, among many other tribal societies identified by anthropologists.

There are some cultures in Asia which stigmatize cousin marriage, in some instances even marriages between second cousins or more remotely related people. This is notably true in the culture of [[Korea]]. In South Korea, before 1997, two people with the same last name and clan were prohibited from marrying. In light of this law being held unconstitutional, South Korea now only prohibits up to third cousins (see [[Article 809 of the Korean Civil Code]]). [[Hmong people|Hmong]] culture prohibits the marriage of anyone with the same last name{{nbsp}}{{ndash}} to do so would result in being shunned by the entire community, and they are usually stripped of their last name.<ref>{{Cite book|url=https://books.google.com/books?id=kgaGCwAAQBAJ&q=Hmong+culture+prohibits+the+marriage+of+anyone+with+the+same+last+name&pg=PA192|title=Hmong Refugees in the New World: Culture, Community and Opportunity|last=Vang|first=Christopher Thao|date=16 May 2016|publisher=McFarland|isbn=9781476622620}}</ref>
