I have a GIS project as part of my spatial analysis subject at the University of Houston. I am undertaking an Environmental Justice (EJ) Analysis of the proposed Dallas-Houston High Speed Rail. In December 2017, the Federal Railroad Administration (FRA) published the DEIS that includes EJ analysis that uses ACS 2014 5-year estimate. I am re-analyzing the EJ analysis using the ACS 2016 5-year estimate.
I am trying to figure out how the low-income population at the block group level is determined using the ACS 2014 5-year estimate. I looked at the income tables including Table B19001 (which is households), but couldn't quite follow how to obtain the proportion of individuals as outlined in the below DEIS EJ analysis methodology:
Low-income communities o The combined proportion of individuals at or below the USCB’s poverty threshold living in a Study Area census block group equals 50 percent or greater, or o The combined proportion of individuals at or below the USCB’s poverty threshold living in a Study Area Census block group equals twice (or greater) the proportion of low-income individuals in the county For the purpose of this analysis, low-income block groups are identified where the average median income falls below $24,300 (poverty threshold for a family of four as determined by the USCB).
Here is a sample of table showing low-income EJ by block group.
I would greatly appreciate your kind assistance.
