(b) Upon receipt of such information for each incarcerated person subject to the jurisdiction of the department of corrections and community supervision, the task force shall determine the census block corresponding to the street address of each such person's residential address prior to incarceration (if any), and the census block corresponding to the street address of the correctional facility in which such person was held subject to the jurisdiction of such department. Until such time as the United States bureau of the census shall implement a policy of reporting each such incarcerated person at such person's residential address prior to incarceration, the task force shall use such data to develop a database in which all incarcerated persons shall be, where possible, allocated for redistricting purposes, such that each geographic unit reflects incarcerated populations at their respective residential addresses prior to incarceration rather than at the addresses of such correctional facilities. For all incarcerated persons whose residential address prior to incarceration was outside of the state, or for whom the task force cannot identify their prior residential address, and for all persons confined in a federal correctional facility on census day, the task force shall consider those persons to have been counted at an address unknown and persons at such unknown address shall not be included in such data set created pursuant to this paragraph. The task force shall develop and maintain such amended population data set and shall make such amended data set available to local governments, as defined in subdivision eight of section two of the municipal home rule law, and for the drawing of assembly and senate districts. The assembly and senate districts shall be drawn using such amended population data set.

(c) Notwithstanding any other provision of law, the information required to be provided pursuant to subdivision eight of section seventy-one of the correction law shall be treated as confidential and shall not be disclosed by the task force except as aggregated by census block for purpose specified in this subdivision. * NB Repealed June 30, 2020
