【正文】 Living with parents edges out other living arrangements for 18 to 34 yearolds[A] Broad demographic (人口的)shifts is marital status, educational attainment and employment have transformed the way young adults in the . are living, and a new Pew Research Center analysis highlights the implications of these changes for the most basic element of their lives—where they call home. In 2014,for the first time in more than 130 years, adults ages 18 to 34 were slightly more likely to be living in their parents’ home than they were to be living with a spouse or partner in their own household.[B] This turn of events is fueled primarily by the dramatic drop in the share of young Americans who are choosing to settle down romantically before age 35. Dating back to 1880, the most mon living arrangement among young adults has been living with a romantic partner, whether a spouse or a significant other. This type of arrangement peaked around 1960, when 62% of the nation’s 18to 34yearolds were living with a spouse or partner in their own household, and only oneinfive were living with their parents.[C] By 2014, % of young adults were living with a spouse or partner in their own household, below the share living in the home of their parent(s) (%). Some 14% of young adults lived alone, were a single parent or lived with one or more roommates. The remaining 22% lived in the home of another family member (such as a grandparent, inlaw or sibling (兄弟姐妹)), a nonrelative, or in group quarters like college dormitories.[D] It’s worth noting that the overall share of young adults living with their parents was not at a record high in 2014. This arrangement peaked around 1940, when about 35% of the nation’s 18to 34yearolds lived with mom and/or dad (pared with 32% in 2014). What has changed, instead, is the relative share adopting different ways of living in early adulthood, with the decline of romantic coupling pushing living at home to the top of a much less uniform list of living arrangements.[E] Among young adults, living arrangements differ significantly by gender. For men ages 18 to 34, living at home with mom and/or dad has been the dominant living arrangement since 2009, In 2014,28% of young men were living with a spouse of partner in their own home, while 35% were living in the home of their parent(s). Young women, however, are still more likely to be living with a spouse of romantic partner(35%) than they are to be living with their parent(s)(29%).[F] In 2014, more young women (16%) than young men (13%) were heading up a household without a spouse or partner. This is mainly because women are more likely than men to be single parents living with their children. For their part, young men (25%) are more likely than young women (19%) to be living in the home of another family member, a nonrelative or in some type of group quarters.[G] A variety of factors contribute to the longrun increase in the share of young. Adults living with the parents. The first in the postponement of, if not retreat from, marriage. The average age of first marriage has risen steadily for decades. In addition, a growing share of young adult may be avoiding marriage altogether. A previous Pew Research Center analysis projected that as many as oneinfour of today’s young adult may never marry. While cohabitation(同居)has been on the rise, the overall share of young adults either married or living with an unmarried partner has substantially fallen since 1990.[H] In addition, trends in both employment status and wages have likely contributed to the growing share of young adults who are livin
