> The homelessness response system added 60,143 shelter beds in 2024, but with over 600,000 people entering homelessness for the first time each year, this is deeply inadequate.

> In 61 percent of states and territories, growth in demand outpaced growth in available beds, meaning that they had less capacity to shelter people in 2024 than in 2023.
