Did you know that nearly half of families in the US with children under 4 struggle to afford diapers?

📊 A new data tool from @urbaninstitute.bsky.social looks at data in states and counties to understand where the largest gaps are.

A map of United States counties showing the number of diapers needed to fill the gap faced by families with young children and low-to-moderate incomes each year. Urban areas and large cities are shaded darkly, indicating a large amount of need, while rural areas also indicate the presence of a gap.

Excited to share this new piece from @urbaninstitute.bsky.social @wcurrangroome.bsky.social @andrewrumbach.bsky.social @sara-mctarnaghan.bsky.social and team that gives an excellent data-driven overview of the last 20 years of natural disasters and federal spending in Gulf Coast states. Lots of 📊!
A county-level map of Texas, Louisiana, Mississippi, Alabama and Florida showing the number of major natural disasters since Katrina. The text reads:

Every County in the Gulf Coast Has Suffered at Least 3 Major Disasters since Katrina, and Many Have Experienced 10 or More

Major disaster declarations by county, 2005–24

Source: Federal Emergency Management Agency, “OpenFEMA Dataset: Disaster Declarations Summaries – v2”, accessed July 18, 2025, https://www.fema.gov/openfema-data-page/disaster-declarations-summaries-v2.

Notes: Only major disaster declarations (DR) for natural hazard events are included in this analysis. A time-series chart that shows the cumulative disaster-related property damage from 1992-2023 in Alabama, Florida, Louisiana, Mississippi, and Texas. There are annotations that show that sharp increases in damage align with well-known storms like Hurricane Andrew, Hurricane Katrina, Hurricane Harvey, and Hurricane Ian.

The text reads:
Disaster Damages Continue to Rise in the Gulf Coast Twenty Years after Katrina

Cumulative disaster-related property damage, 1992–2023 ($)

Source: Center for Emergency Management and Homeland Security, Arizona State University, 2025, “Spatial Hazard Events and Losses Database for the United States, Version 23.0,” accessed July 14, 2025.

Notes: All dollar amounts are in 2024 dollars. All per capita figures are calculated based on 2023 population estimates. A time-based stacked column chart that shows the amount of FEMA pre-disaster hazard mitigation assistance funcing by program from 2005-2024, broken out into the following programs: SRL, RFC, FMA, PDM, BRIC, LPDM. The amount of funding trends upwards over time, with large totals over $800 million in 2022 and 23.

The text reads:
FEMA Has Granted Nearly $10 Billion for Hazard Mitigation, Mostly in Coastal Counties

FEMA pre-disaster hazard mitigation assistance funding by program, 2005–24 ($)

Source: FEMA, “OpenFEMA Dataset: Hazard Mitigation Assistance Projects – v4”, accessed July 20, 2025, https://www.fema.gov/openfema-data-page/hazard-mitigation-assistance-projects-v4.

Notes: BRIC = Building Resilient Infrastructure and Communities; FEMA = Federal Emergency Management Agency; FMA = Flood Mitigation Assistance; LPDM = Legislative Pre-Disaster Mitigation program; PDM = Pre-Disaster Mitgation grant program; RFC = Repetitive Flood Claims program; SRL = Severe Repetitive Loss grant program. All dollar amounts are in 2024 dollars. All per capita figures are calculated based on 2023 population estimates. Statewide and other multicounty projects’ funding amounts were attributed to the county level proportionate to county populations.

When I read Mood Machine earlier this year, I began seriously thinking about cancelling my Spotify sub. This piece from @hearingthingsco.bsky.social finally pushed me to act. I've been buying more music from @bandcamp.com, and from now on I'll be using a different platform for streaming.

This week, @urbaninstitute.bsky.social launched the Education-to-Workforce Framework data tool.

This was one of the more complex @svelte.dev apps we've built, and @benkates.com led the way on development and made something really cool with this one.

Screenshot of a series of data visualizations. There are three metrics displayed: Share of students in grade 3 who meet grade-level standards in math, and in language arts, as well as the share of students in grade 8 who meet grade-level standards in math. For each metric, there is a line chart showing the trend from 2013 through 2020 for Cook County, Illinois, the state of Illinois, and the U.S. as a nation. A choropleth map showing the share of students in grade 3 who meet grade-level standards in math by county in the mid-Western United States. Cook county Illinois is highlighted.

NYC’s congestion pricing is a policy miracle: Less traffic, less noise, faster transit, more business sales, more transit revenue. And it hasn’t produced the negative effects outside the cordon zone we were afraid of.

www.nytimes.com/interactive/...
Congestion pricing has improved life in New York City by: reducing cars on the street, speeding traffic (especially at peak hours), speeding buses and making them more reliable, expanding transit ridership, reducing car crashes, reducing noise complaints, and increasing the number of visitors. Fire response times fell in the NYC congestion zone, even as they increased in the rest of the city. Car crashes with injuries fell citywide, but they fell especially dramatically in the congestion pricing zone from 2024 to 2025 Local buses have sped up dramatically in the congestion pricing zone.

Very gratifying to see three data visualization projects we worked on at @urbaninstitute.bsky.social longlisted at the Information is Beautiful awards.

Kudus to @mitchellthorson.com @benkates.com and @arobotwriting.bsky.social for their outstanding work bringing these complex datasets to life.

For the German election we wanted to use a cartogram of German election districts but didn't find anything good, so we created our own. Here's a little nerd thread how the final algorithm worked 🤓 🧵 #gis #cartogram #election #datavis #cartography

New research @urbaninstitute.bsky.social shows that mass deportations would likely worsen the housing shortage by decimating the labor force.

Immigrants make up >23% of the construction workforce & more in FL, TX. About half are estimated to be undocumented immigrants. www.urban.org/urban-wire/m...
Mass deportations would reduce the construction labor force and exacerbate the housing shortage nationwide.

More than 30% of construction workers were born outside the US in California, Florida, Maryland, Nevada, New Jersey, New York, and Texas.

HUD programs support more than 5 million low-income households. They're now under threat of big cuts.

Our new data tool @urbaninstitute.bsky.social provides detailed info about people supported by HUD programs—and funds received—in every state & Congressional district: www.urban.org/data-tools/f...
Almost 600,000 people are supported by HUD affordable housing programs in Texas. Cities, towns, and counties throughout the state receive hundreds of millions of dollars each year in Community Development Block Grants. In Mississippi, federal housing programs support 105,758 people and 53,157 households. These programs support people across all of Mississippi's Congressional districts. Overall, HUD's programs distribute more than $400 million annually into Mississippi alone.

Dismantling the Dept of Ed or disrupting functions like enforcing critical civil rights laws or halting IDEA funding could affect students with disabilities across the US.

The number of public school students with Individualized Education Programs may surprise you:

Even among families who can afford most of their day-to-day needs, many cannot weather unexpected expenses, like trouble with their car or a visit to urgent care.

Urban has new analysis out showing, by state, how many families lack the resources to thrive.

www.urban.org/urban-wire/h...
Tile map showing by state the proportion of families across the US that lack the resources they need to thrive. In Hawaii, the state with the largest share of people in families with resources below the Urban Institute's true cost of economic security (TCES) threshold, 66 percent of people lacked the resources needed to thrive. And in North Dakota, which had the smallest share of people in families with resources below the threshold, 40 percent of people still did not have the resources necessary to achieve economic security.

42% of Americans would live in a smaller home in a more walkable community.

Yet the reality is that, in most metro areas, those communities are few & far between—and they’re typically too expensive for many people to afford.
