About the National Data
Data source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 45.2 percent of persons with current asthma had an asthma attack in 2017 (age adjusted to the year 2000 standard population)
Target: 38.1 percent
Because HP2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
