Baseline: 4.3 percent of adults 18 years and over with visual impairment used vision rehabilitation services in 2017 (age adjusted to the year 2000 standard population)
Number of adults aged 18 years and over who have trouble seeing and use any vision rehabilitation services.
Number of adults aged 18 years and over who have trouble seeing.
Target-setting method details
Linear trend fitted using weighted least squares and a projection at the 25 percent prediction interval.
Target-setting method justification
Trend data were evaluated for this objective. Using historical data points, a trend line was fitted using weighted least squares, and the trend was projected into the next decade. This method was used because three or more comparable data points were available, the projected value was within the range of possible values, and a projection at the 25 percent prediction interval was selected because it was a statistically significant improvement from the baseline. The Healthy People 2030 Workgroup Subject Matter Experts viewed this as an ambitious yet achievable target due to data trends.
Comparable HP2020 objective
Retained, which includes core objectives that are continuing from HP2020 with no change in measurement.
