Final answer:
Family social contexts are changing due to factors like longer lifespans, higher divorce rates, and diverse single lifestyles, which reflect a broader acceptance of different family structures and impact socio-economic aspects like income inequality.
Step-by-step explanation:
Family social contexts are shifting in response to several factors such as longer lifespans, higher divorce and remarriage rates, and a wider range of single lifestyles. There has been an increase in various family structures, including cohabitation, same-sex partnerships, singlehood, and the choice by single people and cohabitating couples to raise children outside of marriage. These changes reflect a broader acceptance of diverse living arrangements and are accompanied by socio-economic implications such as the contribution to the rise in income inequality across households.
