The Changing Economics and Demographics of Young Adulthood: 1975-2016

"This report looks at changes in young adulthood over the last 40 years. It focuses on how the experiences of today’s young adults differ, in timing and degree, from what young adults experienced in the 1970s—how much longer they wait to start a family, how many have gone to college, and who are able to live independently of their parents. This report looks at a snapshot of the young adult population, defined here as 18 to 34 years old, and focuses on two periods: 1975 and today (using data covering 2012 to 2016 to reflect the contemporary period). Many of the milestones of young adulthood are reflected in the living arrangements of young people: when they move out of their parents’ home and when they form families. Because these milestones are tied to young adults’ economic security, the report also focuses on how education and work experience vary across young adult living arrangements..."

The Changing Demographic Profile of the United States
"The United States, the third most populous country globally, accounts for about 4.5% of the world’s population. The U.S. population—currently estimated at 308.7 million persons—has more than doubled since its 1950 level of 152.3 million. More than just being double in size, the population has become qualitatively different from what it was in 1950. As noted by the Population Reference Bureau, “The U.S. is getting bigger, older, and more diverse.” The objective of this report is to highlight some of the demographic changes that have already occurred since 1950 and to illustrate how these and future trends will reshape the nation in the decades to come (through 2050).

The United States Is Getting Bigger. U.S. population growth is due to the trends over time in the interplay of increased births, decreased deaths, and increased net immigration.

The United States Is Getting Older. Aside from the total size, one of the most important demographic characteristics of a population for public policy is its age and sex structure. This report illustrates how the United States has been in the midst of a profound demographic change: the rapid aging of its population, as reflected by an increasing proportion of persons aged 65 and older, and an increasing median age in the population.

The United States Is Becoming More Racially and Ethnically Diverse, reflecting the major influence that immigration has had on both the size and the age structure of the U.S. population. This section considers the changing profile of the five major racial groups in the United States. In addition, trends in the changing ethnic composition of the Hispanic or Latino Origin population are discussed..."
