Last year, Pew Research Center asked over 5,000 adult Americans whether they would rather (1) live in a community with smaller houses that are within walking distance of schools, stores, and restaurants, or (2) live in a community with larger houses, but where schools, stores, and restaurants are several miles away. The result:

On average, most respondents preferred the latter option -- the larger home. However, there are some demographic groups that feel differently. If you're young (under 29), highly-educated, Democratic-leaning, and/or Asian, this survey suggests that you have a preference for smaller houses in more walkable communities.

More specifically, in this chart, it's interesting to note that 62% of Asians (survey only counted English speakers), 55% of those aged 18-29, 54% of those with a post-graduate degree, and 65% of liberal Democrats prefer denser places that allow you to walk to more places.
A lot of this isn't surprising, but I don't think I've seen data supporting such a strong leaning from Asian adults before. What makes this even more interesting is that White and Asian households are by far the two richest ethnic groups in America. And here, when it comes to built form preferences, they're on opposite ends of the spectrum.
Another important consideration is the cost of living in walkable versus car-oriented communities. Generally speaking, the latter is less expensive on a cost per square foot basis for homeowners; though, this obviously doesn't include the indirect costs of transportation and the additional time it to takes to commute places.
It is also more expensive to service and bring infrastructure to more spread-out communities. There are real economies to density. Despite this, higher-density living tends to be more expensive. Part of this has to do with higher build costs and more restrictive zoning, but it could also be a scarcity of supply (most of the US is car-oriented).
Indeed, there is a well-established premium to living in walkable communities, which creates an interesting dynamic. The thing that the majority of people reportedly don't want or don't prefer is actually more expensive. This always makes me wonder: What if this wasn't the case? What would happen if we didn't have this cost-of-living differential?

Here's some data from the Pew Research Center looking at the percentage of young people (18- to 29-year olds) in the US that live with at least one parent. It it based on an analysis of monthly Census Bureau data and is obviously interesting/relevant given that this pandemic seems to have precipitated a number of people moving back home. As of July of this year, 52% of young adults were thought to be living with at least one parent, which is up from 47% back in February.


Newly released data from the US Census Bureau has just revealed that the average household size is increasing for the first time in over 160 years. Put differently, the formation of new households has started to trail overall population growth. And that is causing the average number of people per household to increase.
In 1790, there were about 5.79 people per household in the United States. That number has been in decline pretty much since then, though there was a slight increase in the decade that began in 1850. Last year (2018), the number grew to 2.63 people per household (2.71 for owner occupied households and 2.48 for renter occupied households).
Here are two charts from Chris Fry's recent piece at the Pew Research Center:


So what is causing this?
Well, we know that US fertility rates aren't on the rise. In fact, they're generally viewed as hitting record lows. I say "generally" because there are a number of different ways to measure fertility. There's the general fertility rate, completed fertility, the total fertility rate, and others. But we are seeing some alignment here: fertility rates are down.
One probable explanation is the fact that more Americans are living multi-generationally. According to the Pew Research Center, 1 out of every 5 Americans lived in such a household as of 2016. Part of this may be a result of immigration. Asian and hispanic populations are more likely to live in a multi-generational household compared to white people.
Another demographic trend is the increase in people living in shared quarters, whether that might be with a roommate or someone else. This is interesting because it suggests that there's an affordability constraint. Are people being forced to "double up?" The current co-living trend is at least partially because of this.
These are all noteworthy trends because household formation is viewed as "the underlying driver of long-term demand for new housing." I am assuming that more people per household also means less square footage per person.

At first I was surprised to see these numbers as high as they are. But it's really the 18-24 age bracket that is driving this number up, which makes sense given that a chunk of this demographic is probably in school, not working, and now unable to do much on a campus. Among 25- to 29-year olds, the range is significantly lower, with just over a quarter (26% -> 28%) living with their parent(s).
What I'm curious about now, after seeing this chart, is what is driving some of these regional, ethnic, and gender differences? Why are young midwesterners seemingly less likely to live with a parent compared to those in the northeast? Is it cultural? Economic? Or something else? And is the above an indication that maybe women are more independent than men?
