How To... - Interpret Data
When are health problems increasing or decreasing among specific age and race/ethnic groups?

Surveillance data are analyzed by both time and person characteristics to determine if prevalence is increasing or decreasing for specific groups. The Summary of Trends in Health Indicator by Demographic Variables tables can be used to determine which age, race and ethnicity, and education groups have increasing or decreasing prevalence of a health problem. Another important and effective use of trend data is to evaluate the effect of an intervention program by comparing one time period to another time period or one high risk group to another over time.
