Final answer:
The amount of time that men spent in caring for a newborn tripled (option c) between 1965 and 2011. This change reflects wider shifts in family dynamics, gender roles, and societal expectations. Men have become more involved in parenting as the median age of first marriage has increased and life expectancy rates have continued to rise.
Step-by-step explanation:
Between 1965 and 2011, the amount of time that men spent in caring for a newborn tripled. Societal norms regarding family roles and parenting have evolved considerably over time. Changes in attitudes towards parenting among men can be linked to broader social changes, including an increase in dual-income households, shifts in traditional gender roles, and rising life expectancy rates that have allowed for a more involved parenting style. Despite societal expectations in the past that confined women to home-making roles, over time both men and women have adapted to new societal norms which involve men taking a more active role in child rearing.
The median age of first marriage has increased for both men and women, indicating a shift in priorities and societal values towards education, career development, and personal growth before settling into marriage and starting a family. Meanwhile, life expectancy rates have continued to gradually rise, impacting family dynamics and caregiving roles within the household.
