When selecting more than one component from the same geographical level, Social Explorer provides a total for these components in the "All Selected Geographies" column. This total is for the available geographies only within the same geographical level. When a value is missing from one or more components from the same geographical level, Social Explorer denotes it with an asterisk (*) in the All Selected Geographies column.
A '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variability is not appropriate.
A '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open-ended distribution. A statistical test is not appropriate.
A '**' entry in the margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate.
A ' ' entry in the estimate column indicates that either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.
