DIA (Disproportionately Impacted Area) Maps

Disproportionately Impacted Area (DIA) means a census tract within Washington State where community members are more likely to be impacted by the War On Drugs. Using the census data from 1980, 1990, 2000, and 2010, these areas were determined using a standardized statistical equation to identify areas of high unemployment, low income, higher rates of conviction for drug charges. The maps account for different time periods to account for gentrification.  (Versión en Español)
