Final answer:
The 'baby boom' period from 1946 to 1964 led to societal changes in the U.S. from 1965 to 1980, including the shifting role of women into the workforce and an evolving family structure that moved away from traditional roles and norms.
Step-by-step explanation:
One specific historical change in United States society from 1965 to 1980 that resulted from the trend in birth rates from 1946 to 1964 (known as the 'baby boom') was the shift in the societal role of women and the changing family structure. During the post-World War II period, economic security and the return of military personnel spurred a dramatic increase in birth rates, leading to a large generation known as the 'baby boomers.' By the time the 'baby boomers' started reaching adulthood in the 1960s, birth rates were declining due to a variety of factors, including urbanization, changes in the economy making children more of an economic liability, and advancements in birth control.
These demographic shifts contributed to significant societal changes. As women started entering the workforce in greater numbers, driven by economic necessity and greater gender equality, this altered the image of the 'traditional' family. Social change also unfolded as women found themselves balancing the challenges of career and family, leading to evolving attitudes about marriage and parenting, and the emergence of the 'rebellious teen' as a societal challenge. The 'baby boom' generation itself was aging into a demographic that was reshaping society through their sheer numbers and influence.
