interviewers surveyed key informants throughout Orange County to collect detailed descriptions of
where homeless persons could be found.
Cwas then asked to identify other knowledgeable individuals in the County who could provide information about additional locations.
The data were compiled, culled for duplicates, and a final list of 289 unique
throughout the county was produced.
These locations were mapped and proximate locations grouped into “Clusters” for sampling purposes.
Survey teams used detailed neighborhood maps to reach locations, enumerate the homeless persons
conduct the survey.
On the night of the 2005 Point in Time survey, teams across the county completed an Enumeration Form at each map location. A sample of individuals also completed in- depth surveys which provided valuable information about homelessness in Orange County, but required a significant investment of volunteer time. In 2007, in-depth interviews will be conducted after the Point in Time survey leaving volunteers free to search and count.
899 ‘surface study areas’ assigned a density of High (6 or more homeless individuals), Medium (2 to 6), or Low (1 or none); 54 areas were classified as High, 139 as Medium, and 706 as Low. Assignment based on information from outreach workers, the Parks Department, New York City Police, the Transportation Authority, Community Boards, and other “density experts” familiar with the location of unsheltered homeless individuals. A complete count of all high-density areas was attempted. A sample of medium-density areas was drawn to achieve 95% confidence that the weighted count was within 10% of the actual number in these areas. Fewer Low-density areas were sampled.
