The census conducted Wednesday was not expected to be as robust as last year's count, which was a biannual survey required by the federal government.
But officials say information gathered in the "point-in-time" look will help them develop plans to provide the homeless with shelter and permanent housing.
Experts say there were about 14,000 homeless people in New Jersey last year - a figure that includes those who were living in temporary housing but still fell under the definition of homeless.
In 2009, the state's homeless population totaled about 13,000.
