History: United States Of America, 1900-1930

According to Geert Hofstede's cultural dimensions analysis, the United States has the highest individualism score of any country studied. While the mainstream culture holds that the United States is a classless society, scholars identify significant differences between the country's social classes, affecting socialization, language, and values. The American middle and professional class has initiated many contemporary social trends such as modern feminism, environmentalism, and multiculturalism. Americans' self-images, social viewpoints, and cultural expectations are associated with their occupations to an unusually close degree. While Americans tend greatly to value socioeconomic achievement, being ordinary or average is generally seen as a positive attribute. Though the American Dream, or the perception that Americans enjoy high social mobility, plays a key role in attracting immigrants, various studies indicate that the United States has less social mobility than Canada and the Nordic countries.
Women now mostly work outside the home and receive a majority of bachelor's degrees. In 2007, 58% of Americans age 18 and over were married, 6% were widowed, 10% were divorced, and 25% had never been married. Same-sex marriage is contentious. Some states permit civil unions in lieu of marriage. Since 2003, several states have permitted gay marriage as the result of judicial or legislative action, while voters in more than a dozen states have barred the practice via referendum.
