So, @marissajae.bsky.social and I knew D.C. was changing up its canopy, but we wanted to explore what which regions of the country would be most represented in the city’s planting strategy.

The data pointed to the midwest and gulf coast.

More than 15 million people 55 or older don’t have a spouse or biological children; nearly 2 million have no family members at all.

Who will be there for these solo agers as their lives draw to a close? How many of them will die alone?
An age-old fear grows more common: ‘I’m going to die alone’
As families fracture, people are living longer and are more likely to find themselves without close relatives or friends at the end of their lives.

From 2020 - 2023, youth crime in DC spiked, and we investigated why. We found a series of failures to address the very problem leaders promised to solve, finding the systems put in place to help DC's youth often fell short with dire consequences.

Kids brave commutes that can stretch over an hour on a transit system that struggles to deliver reliable service.

We modeled over 4,000 unique trips to school, tracked the live location of hundreds of buses for months and spoke to dozens of students.

We tracked every MTA bus Baltimore students ride to school. Here’s how.
This first-of-its-kind analysis shows it’s nearly impossible for city students to get to school on time every day on public transit.
