Point in Time 2005 - What We Did… • Using a “snowball” technique, SSRC interviewers surveyed key informants throughout Orange County to collect detailed descriptions of outdoor locations where homeless persons could be found. • Each key informant was then asked to identify other knowledgeable G o C n o e d l p o g d e t p a m D D a L n n C a o l S i M A l c n a c h P e r a p r V i e L P l b r i a y a S g i B n d W e h i e b l O e a F i s h a m C i n i r n a e t v a l a S v e l e r P a a l g i L e o H r z z t l a i a z a a i l a H l z P e q o n u a l C o O d l t l a P l u r e g t h e h a r d e d S s m i A l i p e r a z m a n s o a n n t e n r C L o o a n t g a a r M a Z t i n t Z a r o s e r i e r n i a r D m b y d g i e a a i r B f o u f p o B l u Q a s a k r C a p 5 - i s t I o r C L a L a o v d a n t e r n e r S a n r n l e C a L g a r r t M a a R i d g r z a s t e m r r i n o i V a L a e n t M i n a z a z n M m a a n t r l t a V i l a r e b r v o S a g m o e B e d t r h u t i l - R n u F e L e L n s P y a F r a a o s a R n e d a n J u L a n a a n L i C o n t e S a c o t i F o r r e T E l e v a e l t a d o o i C s a t S a n a s o D V h o c i V m l o r e v e a n a a i V S s d t r o e r n a a G o l S o h r e e l r n o v D a n t e P r e L d o a a y s t L p e r C a a n n a s e g D S e n p i a l t o r i a u o g a S n o n C o o n r O l d t L S P o r a s d e c a r o B a P a r n t k e r y n C r L o a n t e n r V D a n i V i o a L a l a y a P C i s V a r a t n a i n d i C a s a t a n a r P o i n H t t P u e r o r b a r a i e w u f B l Vi t n i o P f V C i a V V e r o d a l i f C e I l s a P r D i v E m b a t e t a c c i f i s P a C a i V o a s t D a n a 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 outdoor locations 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 observed there, and conduct the survey.
Three Important Changes in 2007 • From a Census to a Sampling Technique • Broad Community Participation to Rate Block Groups – All interested community members can participate through the internet. • Data Collection Goals – Point in Time Volunteers will enumerate only on the day of the count; in-depth surveys will be conducted one week later.
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.
The New York Model • Sampling for the 2003 count of Manhattan � 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.
Why Sample in Orange County? • The resources needed to scour the entire 798 square miles in our county are not available • A scientific sampling strategy is the only HUD-approved basis for extrapolating to compute the total number of homeless
Orange County is divided into 1,993 Census Block-Groups
Block-groups are typically comprised of 10 to 15 city blocks. Though suburban and rural block-groups may be much larger. The highlighted block-group in this map includes the offices of the OC Partnership in the City of Orange.

An internet based application, developed by the SSRC and CSU Fullerton Geography Department will allow interested community members to provide information about the homeless in each block- group. This application will: • Provide information about the Point in Time Survey • Collect limited information about each user and the source of his/her knowledge of homelessness in Orange County • Provide more complete information to researchers preparing the sample for the count on January 27 th.
