Step 5:
The percentage of children population surrounding the plant ZCTAs were compared to overall state percentages and the
nationwide percentage of this sub-group population, by calculating ratios between the plant ZCTA children populations
compared to statewide and nationwide percentages of children population. Exhibit 7K below displays the results.
