Being on vacation means biking in new locations

A bike is perched against a picnic table beside a bench swing. In the background are trees and a body of water. Boats are resting at anchor in the water.

Spent last weekend in the woods. Saw many lovely things like trees, moss and lichen-covered rocks, the valley shrouded in clouds from above. Freshly full of gratitude for the planet we live on here.

A tree-covered hillside bathed in low sunset light. There is a golden glow where the sun hits the leafless trees on the mountain. The sky is partly cloudy, showing patches of pale blue sky.

A view looking out over an overlook. In the foreground are a path through some trees. The path terminates at rock, beyond which nothing is visible except for a bank of clouds covering the valley below.

Went on a bike camping trip with @718outdoors.bsky.social back in June and had an absolute blast. One of many cycling highlights from 2025!

New viz 📊 published today for @urbaninstitute.bsky.social: Colleagues @wcurrangroome.bsky.social @andrewrumbach.bsky.social and team looked into the recent flooding in the Pacific Northwest and the challenges communities will face recovering, and we mapped the region. www.urban.org/urban-wire/a...

A map of Northwest Washington State, United States. The title reads "The Washington Floods Have Affected Communities in Varied Geographic Areas". The map highlights five counties: Whatcom, Skagit, Snohomish, King, and Pierce. It shows several towns within these counties: Sumas, Burlington, Mount Vernon, Canyon Creek, Everett, Seattle, Kent, and Pacific. The map also highlights several of the region's rivers: Nooksack river, Skagit River, Snohomish River, Snoqualmie River, Green River, and White River. The maps shows the area that is predicted to see catastrophic flooding that includes Burlington, Mount Vernon, Canyon Creek and Everett.

The map lists the following sources: Counties and places from US Census Bureau TIGER/Line files. Rivers from the Washington State Department of Ecology. Predicted catastrophic flooding areas from the National Weather Prediction Service's three-day flood hazard outlook on December 12, 2025.

I spent a pretty big chunk of time this weekend trying to figure out how to make #atproto oauth work in a SvelteKit app. I got it working and I feel like I have experienced an important rite of passage.

A screenshot of a bare bones UI for logging in with an atproto/bluesky account. The input element is filled with the author's handle (mitchellthorson.com) and there is a blue "Login" button beside the input. The text above the input reads "Sign in with your AT Protocol account (Bluesky).

Just landed a pretty big refactor of the Svelte-powered @urbaninstitute.bsky.social data viz component library that fully embraces runes syntax across all of our components. Svelte continues to be a flexible and powerful tool for our work. Check out our code on Github github.com/UrbanInstitu...

The image is a screenshot of a Github release page listing new features for the latest release of the @urbaninstitute/dataviz-component-library package. The changes list reads:

Fix: Typo; Theme size for h2 on smaller screens now renders at proper font size
Breaking: now accepts snippet props for custom background/foreground content and replaces getContext("scrolly") stores with the new useScrollyContext() helper; update slot markup and context access accordingly.
Breaking: SVGMap and its layer components now expose pointer interaction callbacks via props (onclick/onmousemove/onmouseout/onbgclick) instead of on:event listeners, and shared state is provided through useSVGMapContext()—replace any getContext("map") usage and update handler wiring.
Breaking: DatawrapperIframe emits interaction hooks through lowercase callback props such as
onvisrendered/onregionclick instead of Svelte on:event listeners; pass handler functions as props to receive chart events.
Breaking: The exported pymChildStore writable has been removed in favor of the rune-based
usePymChildContext() helper returned by ; import usePymChildContext() to interact with the active pym.js child instance.
Feat: All components use Svelte 5 runes syntax and move away from store-based state where possible.

Today @urbaninstitute.bsky.social launches a new data tool: The American Affordability Tracker. We're collecting data that tracks the rising costs of a secure lifestyle, and indicators of financial distress that are contributing to a growing crisis. See the data here: www.urban.org/data-tools/a... 📊

The image shows a line chart displaying state-level data for the average monthly price of rent. There is 1 line for each state, plus the District of Columbia and the national average. Ohio is highlighted, as it trends steadily upward across the chart.

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. www.urban.org/data-tools/m...

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.

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. apps.urban.org/features/edu...

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.
