引证一些参考文献来证明关于当代年轻人结婚减少现象的看法？

以下是一些参考文献来支持当代年轻人结婚减少的观点：

"The Changing Landscape of Love and Marriage" (2019) by Pew Research Center found that the share of adults who were married in the United States has decreased from 72% in 1960 to 50% in 2017. This decline is particularly pronounced among young adults aged 18-29, where only 26% were married in 2017 compared to 59% in 1960.
"Marriage and Cohabitation in the United States" (2017) by the National Center for Health Statistics found that the percentage of women aged 25-34 who have never been married has increased from 38% in 1995 to 50% in 2015.
"The Decline of Marriage and Rise of New Families" (2010) by the Council on Contemporary Families found that the average age of first marriage has increased from 21 for women and 23 for men in 1960 to 27 for women and 29 for men in 2010.
"The Marriage Gap: The Impact of Economic and Technological Change on Marriage Rates" (2013) by the American Enterprise Institute found that young adults who are less educated and have lower income are less likely to get married, with marriage rates declining more rapidly among this group compared to college-educated young adults.

These studies suggest that there is indeed a trend of decreasing marriage rates among young adults in the United States, and that this trend is driven by a variety of factors such as economic changes, shifting cultural norms, and the rise of new family structures
