Philadelphia is going to lose out this year. We’re going to fall down a notch on one of those the top 10 lists that is actually about real information and not something pulled out of thin air (best city for trick-or-treating, y’all!).

As the Inquirer pointed out in an article dissecting population changes from the latest Census, Phoenix is likely going to surpass us in population this year and become the fifth-largest city in the United States. We’ll probably go down to No. 6, with a 2016 population of 1,567,872, compared to Phoenix, which is expected to grow by about 20,000 residents to about 1,580,000. No more top five and that kind of sucks.

But here’s the thing: Philadelphia is not really losing. We’re on an entirely different playing field, a land-locked, dense, actually urban playing field. Phoenix is not. It and some of the other big cities sneaking up behind Philadelphia in population aren’t playing the same game. They shouldn’t be compared because they are so much bigger in physical area and, in some cases, they continue to count their growth because they’re adding land.

As of today, the city of Phoenix — not the metro area, which would include all their massive suburbs like Chandler and Glendale and Scottsdale — spans about 517 square land miles. Philadelphia spans 135 square miles. That’s about one-fourth the size.

Of the top 10 cities Philadelphia is the smallest in geographic size and it is No. 2 in population density, behind New York City and basically even with Chicago.

City 2015 Population Square land miles Population Density (people per square mile) New York 8,550,405 305 28,034 Los Angeles 3,971,896 472 8,415 Chicago 2,720,556 237 11,479 Houston 2,298,628 655 3,509 Philadelphia 1,567,442 135 11,610 Phoenix 1,563,001 517 3,023 San Antonio 1,469,824 467 3,147 San Diego 1,394,907 325 4,292 Dallas 1,300,082 385 3,376 San Jose 1,026,919 180 5,705

Houston, San Diego, San Antonio and the rest are all much bigger in geographic size than Philly, but Phoenix presents a particularly egregious case. The city has been buying up insane quantities of land to get bigger in the last 50 years.

In 1970, Phoenix was about half its current size but continued to annex land through the ensuing decades. The shopping spree has continued into this millennium, into this year, when boundaries were updated. This city map displays Phoenix and then recommends people call the City Clerk Department to see if anything new has been annexed and the map is already outdated. In other words, they’re cheating growing so fast they’re not bothering to keep up with themselves

What does it feel like to have 517 square miles of land in a city? Well, I was just in Phoenix a few weeks ago. It is a never-ending strip mall.

I’m not saying this as an insult. I like Phoenix. It has wonderful Mexican food, Saguaro cacti (the coolest type of cactus), In-N-Out Burger and Shake Shack, a mountain you can hike in a couple of hours just outside the (ridiculously huge) city limits and a cute little restaurant next to a Farmer’s Market that is stocked with farm-fresh foods from said farmer’s market. This eatery is a phenomenal idea.

So, yes, Phoenix is good. But it just happens to be a fact that Phoenix is one big, sprawling strip mall and outside of maybe a couple areas of the city identical to its bordering suburbs.

Philadelphia might sprawl in certain areas of the Northeast and Northwest but for the most part we’re full. Bar’s closed. Our density rate in Center City is even higher than the rest of Philly, at 29,000 per square mile.

In other words, we’re a bustling city. We could certainly be bigger in population — and used to be bigger — but one thing we’re not doing is buying portions of Montgomery County and South Jersey and claiming them for Philadelphia.

So sorry, Phoenix. Enjoy your crowded 12-lane highways and Friday nights at mall bars in Scottsdale (but seriously enjoy the great weather, we’re all jealous). On paper, you will soon enjoy the distinction of being one of America’s top five biggest cities.

In the mind of any person who doesn’t live in a desert, you will not even be close.
