METHODOLOGY NOTES (across all datasets for this indicator)

All legal boundaries and names for Census geography (metropolitan statistical area, county, city, tract) are as of January 1, 2010, released beginning November 30, 2010 by the U.S. Census Bureau. A priority development area (PDA) is a locally-designated infill area with frequent transit service, where a jurisdiction has decided to concentrate most of its housing and jobs growth for development in the foreseeable future. PDA boundaries are as current as July 2016. Population estimates for PDAs were derived from Census population counts at the block group level for 2000-2014 and at the tract level for 1970-1990.

Population estimates for Bay Area counties and cities are from the California Department of Finance, which are as of January 1st of each year. Population estimates for non-Bay Area regions are from the U.S. Census Bureau. Decennial Census years reflect population as of April 1st of each year whereas population estimates for intercensal estimates are as of July 1st of each year. Population estimates for Bay Area tracts are from the decennial Census (1970 -2010) and the American Community Survey (2008-2012 5-year rolling average; 2010-2014 5-year rolling average). Population estimates for Bay Area PDAs are from the decennial Census (1970 - 2010) and the American Community Survey (2006-2010 5 year rolling average; 2010-2014 5-year rolling average.

Estimates of density for tracts and PDAs use gross acres as the denominator.

Annual population estimates for metropolitan areas outside the Bay Area are from the Census and are benchmarked to each decennial Census. The annual estimates in the 1990s were not updated to match the 2000 benchmark.

The DC Metropolitan Area Drug Study (DCMADS) was conducted in 1991, and included special analyses of homeless and transient populations and of women delivering live births in the DC hospitals. DCMADS 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 under-represented in household surveys.The DCMADS: Household and Non-household Populations examines the prevalence of tobacco, alcohol, and drug use among members of household and non-household populations aged 12 and older in the District of Columbia Metropolitan Statistical Area (DC MSA). The study also examines the characteristics of three drug-abusing sub-groups: crack-cocaine, heroin, and needle users. The household sample was drawn from the 1991 National Household Survey on Drug Abuse (NHSDA). The non-household sample was drawn from the DCMADS Institutionalized and Homeless and Transient Population Studies. Data include demographics, needle use, needle-sharing, and use of tobacco, alcohol, cocaine, crack, inhalants, marijuana, hallucinogens, heroin, sedatives, stimulants, psychotherapeutics (non-medical use), tranquilizers, and analgesics.This study has 1 Data Set.
