  • Ending Prison Gerrymandering in Maryland and New York
    “Maryland Department of Legislative Services (DLS) contracted with the Caliper Corporation, developer of Maptitude (a software program widely used to create legislative districts) to assign the geocoded incarcerated individuals to the appropriate census blocks. Using its Maptitude software, Caliper first removed the incarcerated individuals from the census blocks where the correctional facilities were located. Caliper then assigned each geocoded address to its appropriate census block. Caliper generated tracts and blocks and determined the increase and decrease in population.”
