Fig. 4. Fraction of Louisiana State Senate plans simulated under one data source with a population parity constraint that is invalid when measured under another.
The horizontal axis shows the tolerance constraint for the original simulation on the log10 scale. The vertical axis shows the percent of plans that exceed the intended tolerance according to the evaluation data. The dashed lines show the maximum deviation from parity of the enacted 2010 State Senate map as measured under each dataset. The enacted plan meets the 5% target when measured with the Census, but parity exceeds 5% in both DAS datasets.
