Methods of rounding

1

Every figure is rounded to a whole number. Estimates are rounded to the nearest whole number. 

Margins of error are always rounded up, so that they are never understated. 

The smaller end of each range, shown in the Minimum view, is always rounded down, so that it is never overstated; the “+” signals that the shift is at least that large. 

Where states show the same estimate, the one showing the smaller margin of error comes first. Where more than one state has both the same estimate shown and the same margin of error shown, those states are listed alphabetically. 

One seeming anomaly for states shown in both views: Because the figures are rounded in different directions, the estimate shown minus the margin of error shown will not always equal the figure in the Minimum view; it can differ by a point either way.
