Predicting the US "Average Family" will Look like in 2040

First read topic: Expanding on the idea of that 1960s sociology class, how would you predict the US "average family" will look like in 2040? What will be the role of women?of men? of children? the extended family?
Then read my peer's response to topic.
What an astounding thought it is that the definition of family will continue to evolve. I see evidence of how “family” has changed in my lifetime thus far, so I can only imagine the change in the next 23 years. I will start by saying that as the definition of family continues to expand, I believe there will still be margin, as in, not everyone will fall into these new roles I describe below and some will maintain their role and family makeup as is.
I believe the family unit will continue to expand in its definition. There is no set "average family" now, so I believe we will move even further from an average in the future. As we've seen all throughout this course, there are so many types of people that make up a family; from husband, wife, and children, to two dads and children, to a grandmother raising her grandchildren. There is no set formula for family. So, as we look into the future in 2040, I think this will just increase. I'm sure the number of adults cohabitating instead of marrying will increase and perhaps more adults will put off having kids until even later than what we are seeing now.
Based on our current society and overall shifting roles, I imagine many women in 2040 to be independent, leaders in business and politics, and cultivating a greater sense of empowerment and control. Similarly, I expect that many men will step back from their roles of head of the family, more will stay home with children, and support their counterpart's career endeavors. I do not think that the role of children will change much, as children continue to need the same sort of things even as family evolves: love, basic needs, and security.
As far as extended family goes, I have trouble painting a picture for this. Currently extended family is so different for everyone. For example, all of my extended family lives in a 10 mile radius. However, there are many people who have extended family across the country, and many times, across the world. As social media continues to help people stay connected, perhaps in 2040 extended family will continue to spread out, therefore not playing a huge role in immediate family happenings.
Though it is hard to imagine how different it will really be in 2040, there is no doubt the institution of family has changed in my lifetime, and I believe it will continue to evolve in ways we can't even picture at this point.
