Note: The chart above shows the margin of error, represented
by the lower (|-)and upper (-|) bounds of the 90-percent confidence
interval. The estimate itself is represented by the center of the
confidence interval (•). The confidence interval gives a range
of values likely to include the population true value. The smaller
the confidence interval the more precise the estimate of the
characteristic of interest. Source: U.S. Census Bureau | American Community Survey Office |
