Whenever you’re starting to feel like real estate prices in your city are getting out of hand, just turn your attention to New York. It’ll make you feel better.

The New York Times published an interactive overview of the Manhattan real estate market today. It was spurred on by the fact that the average residential sale price in Manhattan just hit $1.7 million (a new record) and that there’s a growing number of 8-figure apartments being bought up.

Last year half a dozen apartments sold for more than $50 million in the One57 tower at 157 West 57th Street. (The New York Times calls this building the “undisputed center of Manhattan residential extravagance.”)

Here’s one of their diagrams showing the number of residential sales over $10 million in 2009 and then in 2015:

And here’s another one of their diagrams showing the bottom and top 10% of the current market:

It’s interesting to see the clustering in certain areas and also the lack of clustering at the high end around the top of Central Park.

I’ve been a big fan of MIT’s Senseable City Lab since I was a grad student at Penn. Their work sits at the intersection of cities and technology, and so I’ve always found it incredibly fascinating.

Recently, the lab examined data from all of New York’s 13,586 registered cabs and looked for ways that technology and mobile tech could potentially optimize the way the system works today. In particular, they were interested in examining instances where people were heading to the same place at the same time, and were within no more than a 3 minute walk of each at the start of the trip.

What they found was that, of the 150 million taxi rides taken in New York City during 2011, almost 80% of them could have been shared.

That is, 80% of the time, there was an overlap in both time and route. That’s an hugely interesting stat because it starts to show just how much waste and inefficiency there currently is in the system. Think about all the trips and carbon emissions that could be potentially eliminated through optimization.

Here’s a video they produced on the project. Click here if you can’t see it below.

It’s a great example of how technology is and will continue to creep into every segment of the economy. It’s exactly what I was talking about in my post, “Disrupting everything.”

Almost 70% of commutes in New York City are done by walking, biking or taking transit. That’s the highest of any American city according to Atlantic Cities:

Probably the biggest driver of this is urban density. That’s because walking, biking and taking transit becomes impractical when you live in a sprawling city. If you want to get people out of their cars, pay attention to the urban fabric of your city.

As someone who used to drive to work (out of necessity), but now relies predominately on public transit, I see one of the big advantages as time. If you’re like me, you probably feel time poor. Taking transit gives me a block of time in which to respond to emails, catch up on reading and generally just think.

In fact, this blog post was written on the subway.
