Differences in characteristics between the monitored sewershed and the countywide or statewide populations.

Rows with bolded fonts mean the difference is statistically significant at a significance level of 0.05. Rows shaded in grey mean the difference between the sewered and unsewered population is meaningful (greater than 5 percentage points or 5%). Note: The margin of error (MOE) for the monitored and whole populations was calculated using the MOE estimates published by the Census Bureau and following the formula: square root of the sum of squared margin of errors. Statistical significance is assessed based on the absolute value of the Z statistics (*** for |Z| > 3.29, ** for |Z| > 2.58, * for |Z| > 1.96). (XLSX)
