Thanks! Yeah I wasn't really satisfied with the legend appearance (and the fiscal capacity ratio itself isn't an immediately obvious concept). Appreciate the perseverance!

America’s oldest Black town is in Illinois β€” and it’s dying. But the fight has begun to save it. America’s oldest Black town is Brooklyn, Illinois. Once an Underground Railroad stop, it’s now dying. A race is on to save it.

We also have data on the municipalities that are most disadvantaged relative to their metro (think Detroit, Newark, etc., but also tiny cities that are in even worse straights) www.chicagotribune.com/2025/01/05/b...

With this data, you can identify which individual jurisdictions have per capita tax bases way higher than their metro averageβ€”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.

We conceptualize β€˜tax base fragmentation’: the spatial concentration (within a metro area) of property wealth in particular wealthy municipalities. The concept is intuitiveβ€”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
