Fairfax County's first "Registry Week" as part of its effort to end homelessness in the county found that most of the area's homeless population lives along the Route 1 corridor.

The effort, done to help officials reach out to those in need, found that 151 homeless residents live along the major county roadway, and that nearly a quarter of all county homeless people are between 18 and 34 years old. More than three-quarters of the interviewees were male, the study found.

"We learned that chronic homelessness comes in many forms for many reasons," said Pam Mitchell, executive director of New Hope Housing. "Solutions require stable affordable housing... and people who care."

Nearly 2,900 homeless people have been recorded in Fairfax County within the last year, records show. County officials hope to house at least 150 of its most vulnerable, chronically homeless residents in supportive housing by 2016.
