The DC Metropolitan Area Drug Study (DC*MADS) was
conducted in 1991, and included special analyses of homeless and
transient populations and of women delivering live births in the DC
hospitals. DC*MADS was undertaken to assess the full extent of the
drug problem in one metropolitan area. The study was comprised of 16
separate studies that focused on different sub-groups, many of which
are typically not included or are underrepresented in household
The Homeless and Transient Population
study examines the prevalence of illicit drug, alcohol, and tobacco
use among members of the homeless and transient population aged 12 and
older in the Washington, DC, Metropolitan Statistical Area (DC
MSA). The sample frame included respondents from shelters, soup
kitchens and food banks, major cluster encampments, and literally
homeless people. Data from the questionnaires include history of
homelessness, living arrangements and population movement, tobacco,
drug, and alcohol use, consequences of use, treatment history, illegal
behavior and arrest, emergency room treatment and hospital stays,
physical and mental health, pregnancy, insurance, employment and
finances, and demographics. Drug specific data include age at first
use, route of administration, needle use, withdrawal symptoms,
polysubstance use, and perceived risk.

Date of Collection:
Unit of Observation:
Persons aged 12 and older in the DC MSA who were either
literally homeless or at imminent risk of becoming homeless, including
persons who spent the previous night in an emergency shelter, in a
nondomicile (e.g., vacant building, city park, car, or on the street)
or who were using soup kitchens or emergency food banks.
Data Collection Notes:
Produced by Research Triangle Institute in Research Triangle Park, NC.
The Homeless and Transient Population study consisted of
908 interviews from four overlapping sampling frames: 477 interviews
with residents in 93 shelters, 224 interviews with patrons of 31 soup
kitchens and food banks, 143 interviews with "literally homeless"
people from 18 major cluster encampments, and 64 interviews with
literally homeless people from an area probability sample of 432
census blocks in the MSA. People who were cognitively impaired and
could not complete the interview were excluded from the
survey. Impairment was defined as extreme intoxification or scoring
more than nine on the Short Blessed Exam (Katzman, Brown, Fuld, Peck,
Schecter, and Schimmel, 1983).
The institutional response rate (i.e.,
for shelters and soup kitchens) was 82.6 percent. The individual
interview response rate was 86.1 percent. The overall response rate
was 71 percent.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
Performed consistency checks.
Created variable labels and/or value labels.
Standardized missing values.
Created online analysis version with question text.
Checked for undocumented or out-of-range codes.
Restrictions: Users are reminded by the United States Department of Health and Human Services that these data are to be used solely for statistical analysis and reporting of aggregated information and not for the investigation of specific individuals or treatment facilities.
