The national racial income gap has changed relatively little, but its geography has shifted considerably. ISR’s @robertmanduca.bsky.social finds disparities narrowed across much of the South while widening in parts of the Northeast and Midwest.
graphic featuring Robert Manduca, quote reads: At the national scale, it looks like nothing has changed, but really what’s happened is that there’s been a pretty big shift in the geography of which places are more racially unequal and which places are less racially unequal; text identifies Robert Manduca as Assistant Professor of Sociology and ISR; ISR logo appears at top left on a blue background.

With this data, you can identify which individual jurisdictions have per capita tax bases way higher than their metro average—benefiting from their regional economies and infrastructure, but not contributing to the regional tax base. They’re municipal tax havens!

Who should care for older adults, especially when dementia is involved? New ISR research led by @spattersearch.bsky.social finds strong expectations for family caregiving, even as families shrink and needs grow. Learn more about this study on caregiving expectations: myumi.ch/kPEqj
Graphic with a quote and a photo of Sarah Patterson, Research Assistant Professor at the Institute for Social Research. Quote text reads: “Our findings show that the public continues to see the family as highly responsible for the care of older adults, but that levels of responsibility vary by relationship type.” Sarah Patterson is smiling, wearing glasses, a yellow cardigan, and black top, with the ISR building in the background.

We conceptualize ‘tax base fragmentation’: the spatial concentration (within a metro area) of property wealth in particular wealthy municipalities. The concept is intuitive—but not captured by existing measures of segregation and jurisdictional fragmentation. Link: academic.oup.com/ser/advance-...

A lot of the discussion of the reconciliation bill has focused--rightly--on the consequences for beneficiaries of these programs. 11 million people are at risk of losing Medicaid coverage, and 4.5 million stand to lose SNAP. That's a ton. But the economic impacts may be even more widespread

In Kentucky's 5th congressional district, recently profiled by Arlie Hochschild for @nytimes.com, Medicaid makes up a quarter of the entire economic base. The SNAP and Medicaid cuts would be like losing one-third of all traded private sector industries www.nytimes.com/2025/06/09/o...

If we look just at the proposed *cuts* to Medicaid and SNAP, it's the economic equivalent of Maine losing its entire forestry and paper manufacturing industries, all at once--or Alaska losing 60% of its oil and gas industry.

Robert Manduca @robertmanduca.bsky.social · 25/06/2025
Put another way, Medicaid contributes roughly as much to Detroit's economy than car manufacturing, more to Houston than the chemical industry, almost twice as much to Los Angeles as motion picture production--these are big numbers!

In some parts of Florida--looking at you, Cape Coral--traditional traded industries make up just *5 percent* of the economic base. The rest of the economy is based on retirement savings, pensions, Social Security, Medicare, etc.

Robert Manduca @robertmanduca.bsky.social · 25/06/2025
Financial income made up another 26%. Traded sector earnings were just 24%: less than either of the other sources, and down from 35% in 2001

Robert Manduca @robertmanduca.bsky.social · 25/06/2025
I compute the share of *all* economic base income that comes from transfers, financial income, and earnings in traded industries (the standard definition). The results are pretty striking: in 2022, transfer payments accounted for *40 percent* of the economic base across US regions

Robert Manduca @robertmanduca.bsky.social · 25/06/2025
Usually, researchers define the economic base = traded industries only. But selling products to other cities or countries isn't the only way money can enter a local economy. I explore two other sources: financial income and government transfers. Like exports, these payments sustain the local sector
