Section 599.5 - Data used for eligibility determinations(a)Source of data. The data to be used in determining the population, poverty rate, unemployment rate and household income distribution information of an area is from the 1990 Decennial Census.(b)Geographic boundaries. The boundary of an area that is nominated for designation as an Renewal Community must coincide with the boundaries of census tracts, as defined in § 599.3 except in the case of Indian reservation areas where the use of census tracts would tend to include areas outside the jurisdiction of the reservation governing body and such body is not making the nomination in concert with another jurisdiction.
