This is a shocking report from Smart Growth America on traffic fatalities in the US. Since 2010, the number of pedestrians struck and killed has increased by almost 75%. As of 2022, this number sat at just over 7,500 fatalities per year:

Here are also the top 20 most deadly metro areas:


Not surprisingly, these hot spots tend to be in the south, as opposed to in older northern cities. And that's because these tend to be car-oriented places. As the name of the report suggests, they are "dangerous by design." If you optimize for cars, it means you're making trade-offs in other places.

According to this recent report by Smart Growth America, which looked at "walkable urbanism" in the largest 35 metro areas in the US, only about 1.2% of land is, on average, built out in this way. Everything else needs to be driven.
But here's the thing. Humans seem to really enjoy walkable urbanism, and will usually pay more for it:
City dwellers will pay to live in a walkable location. Real estate in these areas averages a 34% price premium per square foot in for-sale housing and 41% for multifamily rental apartments.
It also, by definition, punches above its weight:
Walkable neighborhoods in just those 35 metro areas account for 19.1% of the total US real GDP and 6.8% of the total US population, by the researchers’ calculations.
That's how density works. You get to do more, with less.
At the same time, not every place should be Midtown Manhattan (which the report labels as the highest walkable urban place with a floor area ratio of 40). There are a wide range of densities that will work, including modest ones (FARs between 1-3).
Here in Toronto, many of our single-family home neighborhoods have densities that are zoned for a maximum FAR of 0.6, which is quite restrictive if you're hoping to build something like a multi-unit building.
This is, of course, the point. But imagine what all could be done here with even an incremental change.
Smart Growth America released a report this month called Measuring Sprawl 2014. It’s an update to a report they did back in 2002 and it’s worth a read if you’re into urban planning. You can download it here.
The report looks at 221 metro areas in the US and develops a “sprawl index ranking.” The higher the number, the more compact the metro area. Not surprisingly, New York tops the list with San Francisco coming in second. But more interesting are the correlations they discovered. As you go up their sprawl index ranking (that is, as the cities become more compact), they found the following:
People have greater economic opportunity in compact and connected metro areas.
People spend less of their household income on the combined cost of housing and transportation in these areas.
People have a greater number of transportation options available to them.
And people in compact, connected metro areas tend to be safer, healthier and live longer than their peers in more sprawling metro areas.
If you’re a follower of smart growth, then some of these will sound familiar. But they’re worth repeating and I’d like to focus on the second one for a minute (not to undermine the importance of living longer). Conventional wisdom dictates that as you sprawl out from the center of a city, the cost of housing drops. And indeed, that’s what they found. There’s a correlation between density and housing costs, and more compact cities generally have more expensive housing.
However, they also found that the percentage of income spent on transportation is much less in compact metros:
Each 10 percent increase in an index score was associated with a 3.5 percent decrease in transportation costs relative to income. For instance, households in the San Francisco, CA area (index score: 194.3) spend an average of 12.4 percent of their income on transportation. Households in the Tampa, FL metro area (index score: 98.5) spend an average of 21.5 percent of their income on transportation.
But here’s where it gets interesting: they found that transportation costs dropped faster than housing costs increased as metro areas became more compact. Meaning if you consider both housing costs and transportation costs in aggregate, it’s actually cheaper to live in more compact areas. From what I can tell, they’re also only considering direct transportation costs and not indirect costs such as the time people waste sitting in traffic.
Either way, it’s something to consider the next time you’re thinking about where to live and how much you should be willing to spend on housing. That cheaper suburban home may not be as cheap as it seems.
