The latest US consumer price index report was recently published and for the 12-month period ending December 2021, the all items index rose 7.0%. This is the largest 12-month increase since June 1982. Here's a breakdown:
Gasoline (all types): +49.6%
Used cars and truck: +37.3%
Meats/fish/poultry/eggs: +12.5%
New cars: +11.8%
Food at home: +6.5%
Electricity: +6.3%
Food away from home: +6.0%
Apparel: +5.8%
Transportation: +4.2%
Shelter: +4.1%
The obvious standouts here are the price of gasoline and the price of used cars and trucks. Too much demand and not enough supply, it would seem. But the other conspicuous line item for me is shelter at only 4.1%. Is that it?
As Charlie Bilello points out in his latest newsletter, US rents were estimated to be up about 17.8% in 2021 (the highest increase on record according to Apartment List) and the Case-Shiller US National Home Price Index was similarly up about 19% year-over-year.
I also just glanced at the latest Urbanation rental report that came out today, and condominium rents were up 10.8% year-over-year here in the Greater Toronto Area. So I don't know about this 4.1% number. But maybe I just missed something in the fine print.


This evening, when I was reading the internet, I came across this New York Times article from 2017 talking about how San Francisco has the lowest percentage of children of any of the largest cities in the U.S. It’s around 13% of the population. (Supposedly it was the second lowest in 2015. Pittsburgh was first.)
The article goes on to claim that the city has approximately the same number of dogs as it does children. That number is somewhere around 120,000. Not surprisingly, many blame the city’s prohibitive housing costs as the main culprit for the lack of kids. Families simply cannot afford to live in the city.
This got me searching for more information. Richard Florida looked at similar data back in 2015, but it’s important to note that he looked at metro areas and not the city propers. So the data doesn’t speak to whether families were forced to move out from the urban core to the suburbs in search of more affordable housing or for more space.
Nevertheless, he finds no statistical association between the share of children in a city and things like urban density, economic output per capita, or median home prices. He instead finds that the share of children is positively correlated with two main factors: immigration and with ethnicity – specifically people of Latin origin.
Click here if you’d like to read the rest of Florida’s analysis. And if any of you have additional data on this topic, please do share it below. I think I’m going to continue digging into this question of kids and cities.

What happens when wages and real estate prices become too high in a city? Companies start growing in lower cost locations. We’ve all seen this before.
Fred Wilson recently blogged about this “spillover effect”, citing a New York Times article talking about the growth of tech offices in Phoenix. As someone who sits on the board of many technology companies, he was noticing a thematic trend:
“A big theme of board meetings I’ve been in over the past year is the crazy high cost of talent in the big tech centers (SF, NYC, LA, Boston, Seattle) and the need to grow headcount in lower cost locations.”
We talk a lot about housing prices on this blog, and so I think it’s useful to see how this, along with high wages, also impacts companies. The two are interrelated.
Below is a chart from the NY Times article showing the US cities with the highest number of technology jobs and the most growth from 2010 to 2015.

San Francisco is in a league of its own. But overall, the growth is in tech and many cities are adding lots of technology jobs. Look at Detroit and Boston right beside each other (Detroit obviously has a smaller starting base). And look at how Miami is nowhere to be found.
Of course, one interesting question is whether these new outposts – such as Phoenix – can truly come into their own and carve out a niche:
“We don’t want to be San Francisco’s back office — we need more creators here,” said Scott Salkin, a founder and the chief executive of Allbound, which is based in Phoenix, makes sales software and has offices down the hall from Gainsight’s.
Even with the high cost of living, it’s hard to supplant the coastal hegemony. That’s where people go to chase riches. As comedian Daniel Tosh likes to say, “the middle of the country is for people who gave up on their dreams.”
Though for some, living in a place like Denver or Salt Lake City and snowboarding every weekend is a better outcome than living in a studio apartment and commuting an hour to work.
