Childlessness

Childlessness is the state of not having children. Childlessness may have personal, social or political significance.
Childlessness, which may be by choice or circumstance, is distinguished from voluntary childlessness, which is voluntarily having no children, and from antinatalism, wherein childlessness is promoted.
Types.
Types of childlessness can be classified into several categories:
The first three categories are often grouped under the label "involuntary childlessness". The latter category is often called "voluntary childlessness", also described as being "childfree", occurring when one decides not to reproduce.
Statistics.
The analysis of the three broad categories of childlessness (natural sterility, social sterility, voluntary childlessness) outlined above helps to understand how it has changed over the last century in the United States. At the end of the 19th century, income and education levels were low. This made levels of social sterility very high. In addition to the causes mentioned above, the Spanish Influenza epidemics meant that pregnant women who were infected were particularly vulnerable to miscarriages. The Great Depression also impoverished these generations, for whom voluntary childlessness was almost absent. On the whole, the rates of childlessness for married women born between 1871 and 1915 fluctuated between 15 and 20 percent. The rise in both education and overall income allowed subsequent generations to escape from situations where couples were “constrained” from having children, and rates of childlessness began to fall. Over time, the nature of childlessness changed, becoming more and more the chosen outcome of some educated women. A low level of childlessness of 7% was achieved by the generation of the baby boom. It started to rise again for the subsequent generations, with 12 percent of women born in 1964-68 remaining childless. Social causes of childlessness have now completely disappeared for women in union. This is however not true for single women, who are usually poorer, for whom social sterility still exists.
From 2007 to 2011, the fertility rate in the U.S. declined 9%, the Pew Research Center reporting in 2010 that the birth rate was the lowest in U.S. history and that childlessness rose across all racial and ethnic groups to about 1 in 5 versus 1 in 10 in the 1970s. The CDC released statistics in the first quarter of 2016 confirming that the U.S. fertility rate had fallen to its lowest point since record keeping started in 1909: 59.8 births per 1,000 women, half its high of 122.9 in 1957. Even taking the falling fertility rate into account, the U.S. Census Bureau still projected that the U.S. population would increase from 319 million (2014) to 400 million by 2051.
In a paper presented at a 2013 United Nations Economic Commission for Europe work session on Demographic Projections, Swedish statisticians reported that since the 2000s, childlessness had decreased in Sweden and marriages had increased. It had also become more common for couples to have a third child suggesting that the nuclear family was no longer in decline in Sweden.
Causes.
Reasons for childlessness include, but are not limited to, the following:
Solutions for involuntary childlessness.
Medical interventions may be available to some individuals or couples to treat involuntary childlessness. Some options include artificial insemination, intracytoplasmic sperm injection (ICIS) and in vitro fertilization. Artificial insemination is the process in which sperm is collected via masturbation and inserted into the uterus immediately after ovulation. Intracytoplasmic sperm injection is a more recent technique that involves injecting a single sperm directly into an egg, the egg is then placed in the uterus by in vitro fertilization. In vitro fertilization (IVF) is the process in which a mature ovum is surgically removed from a women's ovary, placed in a medium with sperm until fertilization occurs and then placed in the women's uterus. About 50,000 babies in the United States are conceived this way and are sometimes referred to as "test-tube babies." Other forms of assisted reproductive technology include, gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT). 
Fertility drugs also may improve the chances of conception in women.
For those facing social infertility (such as single individuals or same-sex couples) as well as heterosexual couples with medical infertility, other options include surrogacy and adoption. Surrogacy, in this case a surrogate mother, is the process in which a woman becomes pregnant (usually by artificial insemination or surgical implantation of a fertilized egg) for the purpose of carrying the fetus to term for another individual or couple. Another option may be adoption; to adopt is to take voluntarily (a child of other parents) as one's own child.
Contraception.
All forms of contraception have played a role in voluntary childlessness over time, but the invention of reliable oral contraception contributed profoundly to changes in societal ideas and norms. Voluntary childlessness, resulting from contraception has influenced women's health, laws and policies, interpersonal relationships, feminist issues, and sexual practices among adults and adolescents.
The availability of oral contraception during the late 1900s was directly related to the women's rights movement by establishing, for the first time, a mass distribution of a way to control fertility. The so-called "pill" gave women the opportunity to make different life choices they may not previously been able to make, such as for example, furthering their career. This led to monumental changes in the current gender and family roles.
Margaret Sanger, an activist in 1914, was an important figure during the reproductive rights movement. She coined the term "birth control" and opened the first birth control clinic in the U.S. Sanger collaborated with many others to make the first oral contraception possible, these persons include: Gregory Pincus, John Rock, Frank Colton, and Katherine McCormick. The pill was approved by the FDA (Food and Drug Administration) for contraceptive use in the year 1960 and although it was controversial, it remained the most popular form of birth control in the U.S. until 1967 when there was a rise in publicity about the possible health risks associated with the pill; consequently sales dropped twenty-four percent. In the year 1988 the original high-dose pill was taken off the market and replaced with a low-dose pill that was considered to have less risks and some health benefits.
Impacts.
Personal.
For most individuals, for most of history, childlessness has been regarded as a great personal tragedy, involving much emotional pain and grief, especially when it resulted from a failure to conceive or from the death of a child. Before conception was well understood, childlessness was usually blamed on the woman and this in itself added to the high level of negative emotional and social effects of childlessness. “Some wealthy families also adopted children, as a means of providing heirs in cases of childlessness or where no sons had been born.” The monetary incentives offered by Westerners' desire for children is so strong that a commercial market in the child laundering exists.
Psychological.
People trying to cope with involuntary childlessness may experience symptoms of distress that are similar to those experienced by bereaved people, such as health problems, anxiety and depression.
Political.
Specific instances of childlessness, especially in cases of royal succession, but more generally for people in positions of power or influence, have had enormous impacts on politics, culture and society. In many cases, a lack of a male child was also considered a type of childlessness, since male children were needed as heirs to property and titles. Examples of historical impacts of actual or potential childlessness include:
Social.
Socially, childlessness has also resulted in financial stress and sometimes ruin in societies which depend on their offspring to contribute economically and to support other members of the family or tribe. “In agricultural societies about 20 per cent of all couples would not have children because of problems for at least one of the partners. Worry about assuring the desired birth rate could become an important part of family life … even after a first child was born. … In agricultural societies up to half of all children born would die within two years … (Excess surviving children could among other things, be sent to childless families to provide labour there, reducing upkeep demands at home.) When a population disaster hit – like war or major disease – higher birth rates might briefly be feasible to fill out community ranks.”
In the 20th and 21st centuries, when control over conception became reliable in some countries, childlessness is having an enormous impact on national planning and financial planning. In societies where child-bearing is a sign of a high libido, childlessness may be viewed as a sign of low libido. They may also be disparaged with terms like "genetic dead end".
Stigma.
In a society that encourages and promotes parenthood, with its current social norms and culture, childlessness can be stigmatizing. The idea couples should reproduce and want to reproduce remains widespread in North America, contrary to most European cultures. Childlessness may be considered deviant behavior in marriage and this may lead to adverse effects on the relationship of the couple, as well as their individual identities when pertaining to the lack of children being involuntary. For persons that consider that becoming parents was a critical process of their adult family life, a "transition" as Rossi deems it must take place. This transition is from the anticipated parenthood to an unwanted status of nonparenthood. Such a transition may require the individual to readjust their perspective of self or relationship role with their significant other.
