The Liberal Suburb Paradox: How 'Great Schools' Around Boston Encode Class and Geography

Drive through Lexington, Wellesley, Winchester, Concord, or the leafier blocks of Newton on a Saturday morning and you'll see the same set of yard signs, give or take. Science is real. Black lives matter. Hate has no home here. In some yards, all three on the same post.

The houses behind those signs sit on lots that, by zoning rule, can't legally be split or built on more densely. The schools the kids walk to are funded by property taxes that climb in step with home prices that have, in some of these towns, more than doubled in a decade. The median household that could afford to move in next door, according to standard mortgage math, sits comfortably in the top 8 percent of Massachusetts earners.

This is not the part of the story where someone says the signs are fake. Most of the people who put them up genuinely believe what they say. The harder question is what those beliefs have managed to coexist with for the last fifty years, and what they've quietly stopped pushing against.

BMAS Navigator's town-level dataset, built from ACS 2023, the Secretary of the Commonwealth's election results, DESE accountability data, and recent sales pulled from Zillow, lets us look at the same set of suburbs from several angles at once. Pick ten anchor towns inside Route 128 and the data lines up with unusual consistency.

These are not the most extreme cases. They're the well-known ones, the ones any Boston-area parent can name when asked where the 'good schools' are.

Source: U.S. Census ACS 2023 5-year estimates, race fields measured as 'alone' categories; presidential vote share approximated from BMAS Navigator's compiled town-level results. Weston ACS race breakdown is not published at the CDP level in the same form; the town is well documented as one of the highest-income, lowest-Black-share municipalities in the state. The Concord row uses the West Concord CDP, the only census place inside the town with a published race table.

A few things to notice before moving on.

First, the variance in Black population share across these ten towns is a hair above noise. Most sit between 1.4 and 2.6 percent. Dover registers zero in the published ACS estimate. For comparison, Massachusetts as a whole is roughly 9 percent Black and the United States is roughly 13 percent. These suburbs are not slightly under those averages. They are roughly an order of magnitude below them.

Second, the Asian share moves a lot more than the Black or Hispanic shares do. Lexington is 31.6 percent Asian. Brookline and Belmont are around 18 percent. Hingham is 0.3 percent. That spread is its own story, and it has to do with which kinds of households the school-and-price filter actually selects for. We'll come back to it.

Pull median single-family sale prices for these towns from the last twelve months and the floor sits somewhere around $1.4 million (Winchester, Arlington) and the ceiling pushes past $2.5 million (Wellesley, Weston, Dover). To carry a 20-percent-down mortgage on a $1.5 million home at current rates, you need a household income in the high $200s. To carry $2.5 million, you need to clear roughly half a million dollars a year.

The Massachusetts median household income is in the mid-$90s. The national median is in the mid-$70s. Whatever else these communities are doing, they have priced out something like the top 92 to 98 percent of American households as a precondition to entry.

That filter does not announce itself in racial terms. It does not have to. Because of how American wealth is distributed, a filter that admits only the top 5 percent of earners produces a community that is overwhelmingly white and Asian, with a small slice of high-income Black and Hispanic professionals layered in. The filter is, on its face, neutral. The output is not.

Almost every conversation about why families move into these towns ends at the same word: schools. It comes up in casual conversation, in real estate listings, in commute calculations. 'Great schools' is shorthand for safety, stability, aspiration, college admissions, and the kind of intangible social capital that's hard to put a number on.

It is also shorthand for a lot of other things.

School rankings in Massachusetts are dominated by performance on MCAS and access to AP coursework. Both correlate, very tightly, with household income, parental educational attainment, and the density of paid enrichment in a child's life. The same student moved from Lexington to Lawrence does not get worse at math. The school they sit in changes, but a great deal of what makes a 'top' district top has already been baked in before they arrive: the books at home, the tutor on Tuesdays, the parent who can leave work to argue with the IEP coordinator.

This is not an argument against caring about schools. It is an argument about reading rankings honestly. When a district lands in the top ten in Massachusetts, what we are mostly measuring is the concentrated affluence that funded and selected into it.

If you wanted a single piece of evidence that progressive voting at the federal level does not always reach the local zoning board, the MBTA Communities Act fight is the place to look.

The law, passed in 2021 and enforced more aggressively starting in 2023 and 2024, requires the 177 cities and towns served by or adjacent to MBTA transit to permit multifamily housing by-right in at least one district. Not subsidized housing. Not public housing. Just the legal possibility of apartments, near transit, in one zoning district.

The Massachusetts Attorney General's office has had to file suit against towns that refused to comply. Town meetings in some of the ten anchor communities here became theaters of an old genre: traffic concerns, school crowding, 'character of the neighborhood,' wastewater capacity, dark warnings about overdevelopment. The signs in the front yards did not move. The arguments at the microphone shifted into a different vocabulary entirely.

None of those concerns are inherently dishonest. Some towns really do have wastewater limits. School crowding is real. But the consistent pattern across affluent suburbs has been to treat any incremental loosening of single-family-only zoning as an existential threat, even when the proposal is modest, even when it is required by state law, even when the residents arguing against it are wearing pride pins.

It would be cheap to leave this here. Yard signs versus zoning maps, gotcha, end of essay. The more useful version of this argument takes the people on every side of it at their word and asks what tensions they're actually navigating.

What follows is an attempt to do that. Not to grade the camps, just to lay them out.

Step back far enough and a New England town meeting refusing to permit apartments looks less like a contemporary scandal and more like an old form. Societies have been figuring out who counts as an insider since societies existed. Colonial Massachusetts towns voted on who could settle. Postwar suburbs got white through FHA lending rules and racial covenants that the federal government wrote and enforced. The Civil Rights era made overt exclusion illegal. The next generation of exclusion ran through zoning, school district lines, and the price of a single-family lot.

The form keeps updating. The legal language gets more careful. The neighborhood meetings get more polite. The outcomes, on race and class, stay startlingly continuous.

What is new is the gap between how today's affluent liberal suburbs describe themselves and what their zoning maps actually do. Earlier generations of the same towns at least had the consistency of stating their preferences out loud.

The most interesting line in the table is the Asian column. Some of these towns are vastly more racially diverse on the Asian axis than they were a generation ago. Lexington has gone from a town a Cold War commuter would barely recognize to one where roughly a third of residents are Asian, the majority recent professionals from China, India, and Korea.

This is real diversification. It also tells us something important about what the filter is actually selecting for. The filter is not racial. It is economic and credentialed. When the rest of the world's high-earning, high-credential households arrive at the gate, the gate opens. When working-class households of any race arrive, it does not.

The story of these towns becoming more 'diverse' over thirty years is largely the story of becoming more racially Asian, while the Black and Hispanic shares barely move. That is what an income filter looks like when income is unevenly distributed across racial groups in America. It is not a coincidence and it is not an accusation.

Two things almost never get said at the same time, and they probably should.

One: the affluent Boston suburb produces real public goods. The schools are, on absolute measures, very good. The streets are safe. Public services work. Trash gets picked up. Civic life functions. People who live here are not crazy to value those things. They are not making them up.

Two: the way those public goods are produced involves walling off enough of the metro that the people who keep it running cannot afford to live in the towns whose lawns they mow, whose classrooms they teach in, and whose elderly relatives they care for. The teachers in Wellesley mostly commute from somewhere cheaper. The same is true of the EMTs in Weston and the line cooks in Lexington Center. This is not a moral failing of any individual resident. It is a structural feature of the arrangement.

A serious conversation has to hold both of those at once. Most of the public conversation only holds one at a time, depending on the political instincts of the speaker.

If the affluent liberal Boston suburb wanted to close the gap between its stated values and its lived outcomes, the moves are not mysterious. They are politically uncomfortable. They include:

• Permitting multifamily housing by-right in more than the minimum district required by state law.
• Lowering minimum lot sizes and parking minimums.
• Allowing accessory dwelling units broadly, not grudgingly.
• Funding affordable housing with local revenue rather than only federal pass-throughs.
• Resourcing schools to support a wider range of household incomes, not just to maintain the current homogeneous high.
• Treating racial and economic integration as a community project with a budget, not a values statement on a website.

None of these requires demonizing anyone currently in the town. All of them require the residents of these towns to accept some loss of control, some uncertainty, and probably some moderation in the appreciation curve of their largest asset.

Whether towns will do any of that, on any meaningful timeline, is the open question. So far, the pattern has been to do the minimum legally required and call it leadership.

It is easy to read a piece like this and reach for the nearest tribal flag. Conservative readers will see confirmation that liberal elites are hypocrites. Progressive readers will see an unfair attack on towns full of decent people doing their best. Both reactions are too tidy.

The more useful reading is the one that sits with the contradiction. People who genuinely hold inclusive values can still vote, year after year, for local arrangements that produce exclusion. That happens because the local arrangements are intertwined with the things those same people are trying to protect: their kids' education, their savings, the stability of the place they live. The conflict is internal. It plays out at town meetings as procedural arguments because that is the only register in which it can be argued without anyone losing face.

Noticing the contradiction is the first move. Living with it honestly is the second. Doing something about it is the third, and that one almost never happens without outside pressure.

We're building town-level pages that combine demographics, voting, school data, recent sales, and zoning posture into a single view, so readers can stop relying on rankings written by national outlets that don't know the difference between Newton Corner and Newton Centre. If you want to poke around the existing version, Discover Towns is the place to start, and the per-town pages such as Lexington, Newton, Brookline, and Wellesley are reasonable entry points.

If you want to see how the data we used in this piece compares to other parts of the metro, the Boston Metro Voting Patterns Interactive Town Analysis is a good companion. So is the Country Club Prestige Premium piece for a slightly more pointed take on what 'prestige' actually buys.
