Various countries, states, and cities have come up with differing means and techniques to calculate an approximate count. For example, a one night "homeless census count", called a point-in-time (PIT) count, usually held in the early Winter, for the year, is a technique used by a number of American cities, especially Boston, Massachusetts. Los Angeles, California uses a mixed set of techniques for counting, including the PIT street count. In 2003, The United States Department of Housing and Urban Development (HUD) had begun requiring a PIT count in all "Continuum of Care" communities which required them to report the count of people, housing status, and geographic locations of individuals counted. Some communities will give sub-population information to the PIT, such as information on veterans, youth, and elderly individuals as done in Boston.
