Maps show new class divisions at work in US cities

In the 1920s and 30s, scholars at the Chicago School of urbanism came up with a standard model, in which the city was a series of concentric circles. At its centre, they placed factories and employment centres; these were surrounded by working class housing. Then came the middle classes, and finally, at the city’s edges, those with the highest incomes.

Anyone who’s visited the US recently can tell you this model no longer holds (there’s a real scarcity of factories in Times Square these days). But a study released by the Martin Prosperity Institute in September goes further: now, it argues, this model has now been completely inverted.

A team of researchers, including urbanist Richard Florida and cartographer Zara Matheson, used 2010 census and survey data to map the class breakdown of 12 major US cities. Unlike the Chicago School team, however, they didn’t classify people by wealth, but by three classes of employment: the confusingly named “creative class”, which includes professional jobs like lawyers or doctors; the “service class”; and the “working class”, meaning manufacturing or factory workers.

The study found that the creatives increasingly dominate the centre of most cities; where there’s a waterfront, they also cluster there. Meanwhile, those with service jobs tend to live further out. True working class neighbourhoods are now a relative rarity.

The economic centre of New York, for example, is Manhattan. The island is now almost exclusively occupied by the creative and professional class, except for a few service-dominated areas in Harlem or on the Lower East Side. The outer boroughs are dominated by the service class, while only a handful of areas in Queens and the Bronx are even 50 per cent working class these days:

The study doesn’t include comparative historical maps, but just about every film ever set in New York tells you that this wasn’t always true. In the 20th century, Manhattan was dominated by recent migrants living in tenements. This “creative class” concentration is a recent phenomenon, a result of the city’s shift away from an industrial economy.

Other post-industrial metros like Boston show a similar pattern, though there are a few service workers still living in the south-central part of the city:

The outer edges of Houston are still dotted with petrochemical and aerospace factories. Consequently, the city still has a few working class neighbourhoods on its outskirts:

Is any of this a problem? The study concludes that it has identified “clear and unmistakeable patterns of class division”, which doesn’t sound great. But the Chicago School model suggests that this has probably always been the case.

What has changed is where people want to live, given the choice. With the disappearance of heavy industry and the accompanying noise and pollution, city centres are now more attractive to wealthier residents. And, as industry moves elsewhere, the number of blue-collar jobs in cities is falling.

It might be those brown and beige clumps representing the service class, almost always slightly outside the economic centre, which we should be worrying about. The study identifies what it calls “areas of urban disadvantage”: suburbs populated by those who may well work in service jobs in the city centre, but can only afford to live at its fringes. An income map of New York effectively mirrors the job-based map above:

In other words, the Martin Prosperity Institute maps are about income after all. As richer people move in, property prices go up – and it gets harder and harder for those who aren’t wealthy to live near city centre.

CityMetric is now City Monitor! Come see us at our new home

City Monitor is now live in beta at

CityMetric is now City Monitor, a name that reflects both a ramping up of our ambitions as well as our membership in a network of like-minded publications from New Statesman Media Group. Our new site is now live in beta, so please visit us there going forward. Here’s what CityMetric readers should know about this exciting transition.  

Regular CityMetric readers may have already noticed a few changes around here since the spring. CityMetric’s beloved founding editor, Jonn Elledge, has moved on to some new adventures, and a new team has formed to take the site into the future. It’s led by yours truly – I’m Sommer Mathis, the editor-in-chief of City Monitor. Hello!

My background includes having served as the founding editor of CityLab, editor-in-chief of Atlas Obscura, and editor-in-chief of DCist, a local news publication in the District of Columbia. I’ve been reporting on and writing about cities in one way or another for the past 15 years. To me, there is no more important story in the world right now than how cities are changing and adapting to an increasingly challenging global landscape. The majority of the world’s population lives in cities, and if we’re ever going to be able to tackle the most pressing issues currently facing our planet – the climate emergency, rising inequality, the Covid-19 pandemic ­­­– cities are going to have to lead the way.

That’s why City Monitor is now a global publication dedicated to the future of cities everywhere – not just in the UK (nor for that matter just in the US, where I live). Our mission is to help our readers, many of whom are in leadership positions around the globe, navigate how cities are changing and discover what’s next in the world of urban policy. We’ll do that through original reporting, expert opinion and most crucially, a data-driven approach that emphasises evidence and rigorous analysis. We want to arm local decision-makers and those they work in concert with – whether that’s elected officials, bureaucratic leaders, policy advocates, neighbourhood activists, academics and researchers, entrepreneurs, or plain-old engaged citizens – with real insights and potential answers to tough problems. Subjects we cover include transportation, infrastructure, housing, urban design, public safety, the environment, the economy, and much more.

The City Monitor team is made up of some of the most experienced urban policy journalists in the world. Our managing editor is Adam Sneed, also a CityLab alum where he served as a senior associate editor. Before that he was a technology reporter at Politico. Allison Arieff is City Monitor’s senior editor. She was previously editorial director of the urban planning and policy think tank SPUR, as well as a contributing columnist for The New York Times. Staff writer Jake Blumgart most recently covered development, housing and politics for WHYY, the local public radio station in Philadelphia. And our data reporter is Alexandra Kanik, whose previous roles include data reporting for Louisville Public Media in Kentucky and PublicSource in Pittsburgh, Pennsylvania.

Our team will continue to grow in the coming weeks, and we’ll also be collaborating closely with our editorial colleagues across New Statesman Media Group. In fact, we’re launching a whole network of new publications, covering topics such as the clean energy transition, foreign direct investment, technology, banks and more. Many of these sectors will frequently overlap with our cities coverage, and a key part of our plan is make the most of the expertise that all of these newsrooms combined will bring to bear on our journalism.

Please visit going forward, where you can also sign up for our free email newsletter.

As for CityMetric, some of its archives have already been moved over to the new website, and the rest will follow not long after. If you’re looking for a favourite piece from CityMetric’s past, for a time you’ll still be able to find it here, but before long the whole archive will move over to City Monitor.

On behalf of the City Monitor team, I’m thrilled to invite you to come along for the ride at our new digs. You can follow City Monitor on LinkedIn and on Twitter. If you’re interested in learning more about the potential for a commercial partnership with City Monitor, please get in touch with our director of partnerships, Joe Maughan.

I want to thank and congratulate Jonn Elledge on a brilliant run. Everything we do from here on out will be building on the legacy of his work, and the community that he built here at CityMetric. Cheers, Jonn!

To our readers, on behalf of the City Monitor team, thank you from all of us for being such loyal CityMetric fans. We couldn’t have done any of this without you.

Sommer Mathis is editor-in-chief of City Monitor.
