Nevertheless, some indication of the level of search interest by adoptees can be gleaned from the case of England and Wales which opened adoptees' birth records in 1975. The UK Office for National Statistics has projected that 33% of all adoptees would eventually request a copy of their original birth records, exceeding original forecasts made in 1975 when it was believed that only a small fraction of the adoptee population would request their records. The projection is known to underestimate the true search rate, however, since many adoptees of the era get their birth records by other means.
The language of adoption is changing and evolving, and since the 1970s has been a controversial issue tied closely to adoption reform efforts. The controversy arises over the use of terms which, while designed to be more appealing or less offensive to some persons affected by adoption, may simultaneously cause offense or insult to others. This controversy illustrates the problems in adoption, as well as the fact that coining new words and phrases to describe ancient social practices will not necessarily alter the feelings and experiences of those affected by them. Two of the contrasting sets of terms are commonly referred to as positive adoption language (PAL) (sometimes called respectful adoption language (RAL)), and honest adoption language (HAL).
The majority of people state that their primary source of information about adoption comes from friends and family and the news media. Nevertheless, most people report the media provides them a favorable view of adoption; 72% indicated receiving positive impressions. There is, however, still substantial criticism of the media's adoption coverage. Some adoption blogs, for example, criticized Meet the Robinsons for using outdated orphanage imagery as did advocacy non-profit The Evan B. Donaldson Adoption Institute.
During the same period, the Progressive movement swept the United States with a critical goal of ending the prevailing orphanage system. The culmination of such efforts came with the First White House Conference on the Care of Dependent Children called by President Theodore Roosevelt in 1909, where it was declared that the nuclear family represented "the highest and finest product of civilization" and was best able to serve as primary caretaker for the abandoned and orphaned. Anti-institutional forces gathered momentum. As late as 1923, only two percent of children without parental care were in adoptive homes, with the balance in foster arrangements and orphanages. Less than forty years later, nearly one-third were in an adoptive home.
Private domestic adoptions: under this arrangement, charities and for-profit organizations act as intermediaries, bringing together prospective adoptive parents and families who want to place a child, all parties being residents of the same country. Alternatively, prospective adoptive parents sometimes avoid intermediaries and connect with women directly, often with a written contract; this is not permitted in some jurisdictions. Private domestic adoption accounts for a significant portion of all adoptions; in the United States, for example, nearly 45% of adoptions are estimated to have been arranged privately.
As the idea of institutional care gained acceptance, formal rules appeared about how to place children into families: boys could become apprenticed to an artisan and girls might be married off under the institution's authority. Institutions informally adopted out children as well, a mechanism treated as a way to obtain cheap labor, demonstrated by the fact that when the adopted died, their bodies were returned by the family to the institution for burial.
Other studies provide evidence that adoptive relationships can form along other lines. A study evaluating the level of parental investment indicates strength in adoptive families, suggesting that parents who adopt invest more time in their children than other parents and concludes, "...adoptive parents enrich their children's lives to compensate for the lack of biological ties and the extra challenges of adoption." Another recent study found that adoptive families invested more heavily in their adopted children, for example, by providing further education and financial support. Noting that adoptees seemed to be more likely to experience problems such as drug addiction, the study speculated that adoptive parents might invest more in adoptees not because they favor them, but because they are more likely than genetic children to need the help.
Family plays a vital role in identity formation. This is not only true in childhood but also in adolescence. Identity (gender/sexual/ethnic/religious/family) is still forming during adolescence and family holds a vital key to this. The research seems to be unanimous; a stable, secure, loving, honest and supportive family in which all members feel safe to explore their identity is necessary for the formation of a sound identity. Transracial and International adoptions are some factors that play a significant role in the identity construction of adoptees. Many tensions arise from relationships built between the adoptee(s) and their family. These include being "different" from the parent(s), developing a positive racial identity, and dealing with racial/ethnic discrimination. It has been found that multicultural and transnational youth tend to identify with their parents origin of culture and ethnicity rather than their residing location, yet it is sometimes hard to balance an identity between the two because school environments tend to lack diversity and acknowledgment regarding such topics. These tensions also tend to create questions for the adoptee, as well as the family, to contemplate. Some common questions include what will happen if the family is more naïve to the ways of socially constructed life? Will tensions arise if this is the case? What if the very people that are supposed to be modeling a sound identity are in fact riddled with insecurities? Ginni Snodgrass answers these questions in the following way. The secrecy in an adoptive family and the denial that the adoptive family is different builds dysfunction into it. "... social workers and insecure adoptive parents have structured a family relationship that is based on dishonesty, evasions and exploitation. To believe that good relationships will develop on such a foundation is psychologically unsound" (Lawrence). Secrecy erects barriers to forming a healthy identity.
Some adoptees reject the idea of reunion. It is unclear, though, what differentiates adoptees who search from those who do not. One paper summarizes the research, stating, "...attempts to draw distinctions between the searcher and non-searcher are no more conclusive or generalizable than attempts to substantiate...differences between adoptees and nonadoptees."
The American model of adoption eventually proliferated globally. England and Wales established their first formal adoption law in 1926. The Netherlands passed its law in 1956. Sweden made adoptees full members of the family in 1959. West Germany enacted its first laws in 1977. Additionally, the Asian powers opened their orphanage systems to adoption, influenced as they were by Western ideas following colonial rule and military occupation. In France, local public institutions accredit candidates for adoption, who can then contact orphanages abroad, or ask for the support of NGOs. The system does not involve fees, but gives considerable power to social workers whose decisions may restrict adoption to standardized families (middle-age, medium to high income, heterosexual, Caucasian).
