Final answer:
70% of boys and 78% of girls ages 15-19 agreed that it's acceptable for an unmarried woman to have a child, showing evolving youth attitudes towards family and single parenting.
Step-by-step explanation:
According to the data from the most recent National Survey of Family Growth, the percentages of boys and girls ages 15-19 who said they "agree" or "strongly agree" that "it's okay for an unmarried female to have a child" are 70% for boys and 78% for girls. This reflects a shift in society's sexual attitudes and the acceptance of various family structures. It also suggests a generational change in the perception of traditional family norms and the acceptance of single parenting and non-traditional family arrangements.
The presence of more unmarried couples cohabitating indicates a transformation in the traditional U.S. family structure, while the positive effects of the legalization of same-sex marriage on the mental and emotional wellbeing of LGBTQ individuals signify a broader acceptance of diverse family dynamics. Given these progressive attitudes among youth, it's not surprising to see a significant shift towards inclusive perspectives on parenting and family structures.
