  "definition": "A test of statistical significance provides statistical evidence that indicates whether an observed difference between two estimates is likely due to chance (\"not statistically significant\"), or likely represents a true difference that exists in the population as a whole (\"statistically significant\").\n\nStatistical significance in Census data products is usually reported at the 90 percent confidence level.\n\nNote that some statistical significance results displayed in American FactFinder may be based on unrounded estimates and standard errors, and users may not be able to duplicate the results using the rounded estimates and measures of error as displayed on American FactFinder.",
