The MTA is apparently well into the middle phase of its project to wire 279 below-ground subway stations with cell reception, but as Citylab recently put it, “there are still places you can’t make a call to save your life.” Into this unfortunate void comes the Subspotting project, brainchild of Daniel Goddemeyer and Dominikus Baur, which offers maps “illustrating the unequal geography of subway reception” and helpfully providing information on where you’ll be able to make a call or send a text while in transit. In addition to system and individual line maps, there’s an app that shows the quality of reception as different sized bars at each station, and MTA-sanctioned posters.

Can you hear me now?

Donald Trump‘s fellow Republican presidential candidates have been focused on him releasing tax documents, but since he claims he’s not in the position to do so since he’s been audited, this little tidbit might make for some good temporary fodder — Trump’s luxury Manhattan properties owe the city for 19 unpaid violations that have amounted to $27,536 over the past 12 years.

I Quant NY scoured the city’s building records to find that since 2000, at least 14 of his Manhattan properties have received 460 separate violations, totaling $304,165 in fines. Sure this may be a drop in the bucket for the GOP frontrunner, but it’s the lack of compliance that seems troubling, especially since only 6 percent of the instances were dismissed. And 2015 had the most violations to date, with 62 separate fines for “Failure to Maintain an Elevator.”

If you’ve got the urge to merge, it might be time for a career change. With the romance-obsessed holiday around the corner, the folks at Bloomberg Business delved into the U.S. Census Bureau’s 2014 American Community Survey to find out which professions are pairing off. To that end, they’ve created a fascinating interactive chart that reveals the most common occupation/relationship marriage matchups for any selected occupation.

Some findings aren’t surprising: “High-earning women tend to pair up with their economic equals, while middle- and lower-tier women often marry up. In other words, female CEOs tend to marry other CEOs; male CEOs are okay marrying their secretaries.”

So Who’s Marrying Whom?

Just before the new year, listings went live for NYC’s first micro apartment complex Carmel Place (aka My Micro NY aka 335 East 27th Street) in anticipation of its opening in March. The nine-story modular development in Kips Bay has 55 studios that are 260 to 360 square feet. Of these, 22 are affordable (more than 60,000 people applied for them), and they’ll go from $950 to $1,500 a month depending on size and income.

The remaining market-rate units will range from $2,500 to $2,900 per month, which has left many skeptics questioning why anyone would fork over nearly three grand for a space that is far smaller than conventional studios. To put this argument into an actual visualization, the data gurus over at NeighborhoodX created a simple, yet informative graph that compares the rental price per square foot at Carmel Place with that of regular studios across the city (h/t Curbed).

Graph: The Council on Tall Buildings and Urban Habitat

Tall buildings help make cities great. Except when they don’t. Citylab looks at a new study and graphs that show where skyscrapers fit into what makes cities great–and suggests that the middle is where the magic happens.

2015 was a record year for the skyscraper; 106 tall buildings (higher than than 656 feet) went up across the globe, according to The Council on Tall Buildings and Urban Habitat (CTBUH), more than in any previous year; emergent countries that appeared at the forefront of the global economic stage with the dawn the 21st century (China, Indonesia, UAE, Russia) show a big uptick in building upward. The majority of newly-built skyscrapers have risen in Asian nations—especially China–but the United States is in sixth place, with just two skyscrapers completed in 2015.

Renting in New York can get exhausting–the dreaded lease renewal letters, the constant moves, the thought of shelling out tens of thousands of dollars each year to pay someone else’s mortgage. But is it really worth it to buy a home in NYC? According to data from personal finance site SmartAsset, it’s only a good decision after you’ve lived in New York for 18.2 years, longer than anywhere else in the nation by far (h/t Business Insider).

The study looked at 29 major cities across the U.S. and calculated their breakeven point–”the point at which the total costs of renting become greater than the total costs of buying.” As a baseline, they used a household earning $100,000 annually with a 4.5 percent mortgage rate, a 20 percent down payment, and $2,000 in closings costs.

From the value of all the Bitcoins in the world ($5 billion) to the amount of total global debt ($199 trillion) to the barely-fathomable amount of the derivatives market (as much as $1.2 quadrillion. Yup. Quadrillion), a chart created by The Money Project, produced by Visual Capitalist, attempts to put all the world’s currency in one place in the form of tiny, little squares (h/t Fast Co. Exist). Starting with the question, “How much money exists in the world?” this data visualization starts with the world’s total money supply.

“For the second year in a row, Manhattan real estate prices soared, setting new records. For the first time, the median price for an apartment—including both co-ops and condos—was above $1 million.” This is according to CityRealty‘s newly released Year-End Manhattan Market Report, which puts the median price at $1.1 million, 13 percent higher than last year and 60 percent higher than 2005. Additionally, the average apartment sales price ($1.9 million), the average condo price ($2.6 million), and the average co-op price ($1.4 million) all broke 2014’s records by $100,000.

When most of us rationalize our outrageous rents (and for buyers, real estate prices), our first go-to argument usually involves something along the lines of how great it is to live so close to work and the bustling city. But as it turns out, there are actually more than a handful of neighborhoods outside of the borders of Manhattan that boast way better commute times than even Brooklyn. Real estate data start-up NeighborhoodX is back again with yet another eye-opening visualization, this time pitting the commute times and real estate prices of various New Jersey, New York and Connecticut suburbs, and a few popular Queens and Brooklyn nabes, against one another.
