Here is an interesting set of maps (from this study) showing density trends, population trends, and residential area trends (i.e. sprawl), across Europe between 2006-2012 and 2012-2018:
The key takeaway is that, broadly speaking, there is -- or at least there was five years ago -- a new density trend across most European cities. From 2006 to 2012, the prevailing trend was de-densification. That is, fewer people per hectare. However, from 2012 to 2018, that trend largely reversed. With the exception of the Iberian Peninsula and Eastern Europe, the majority of cities flipped to densification.
The study tells us that there are two main reasons for this switch. The first is that more cities started growing again. During the first period, about 60% of cities in the sample size of 300+ cities, were adding people. In the second period, this figure increased to 75%. It's also worth noting that this growth is being largely driven by immigration, and increasingly so. The number of cities with positive natural growth diminished from 67% to 51% between the two study periods.
The second driver is a reduction in sprawl. Though almost every city in the study continued to expand outward, the rate of expansion was much lower between 2012 and 2018. So less land consumption, and more people. That's how you increase your urban density. Of course, it would be interesting to see if any of this has changed or reversed (again) as a result of the pandemic. 2018 kind of feels like eons ago, doesn't it?
The Washington Post just published this interactive feature showing new developed land (i.e. urban sprawl) across the US between 2001 and 2019.
This is a chart from a recent blog post by Ryerson University's Centre for Urban Research and Land Development. It shows net intraprovincial migration across the regions of the Greater Toronto Area. And what you are seeing here is people moving from expensive and built-up areas like the City of Toronto and the Region of Peel to lower cost areas further outside of the city.
This is interesting for a couple of reasons. One, it's very much a natural market outcome. Many people tend to "vote with their feet" and look for greater housing affordability. And two, this is a trend that existed prior to COVID-19. It is not the death of cities. In the words of Ryerson's CUR, it's about people looking for more affordable

It is based on these land cover maps which were published by the US Geological Survey earlier in the summer. Their findings show that between 2001 and 2019, more than 10% of the land cover in the lower 48 states changed during this time period. Mostly in forested areas.
The WP feature allows you to search by city/address and I would encourage all of you to try it out. As an example, here is Salt Lake City. The gray areas represent land that was already developed in 2001. The purple areas represent land that was developed sometime between 2001 and 2019.

But to what extent is "lower density" the key deciding factor? In other words, how much of this is consumer preference and how much of this is people being forced out by a lack of infill housing supply?
