What is Health Data for All Ages (HDAA)? • An interactive set of tables presenting data on the health and well-being of the U.S population. • Recently developed by NCHS, with a primary focus on major health concerns across age groups and life stages. • Uses a powerful platform to make detailed, complex data accessible to all users.

A tool for everyone • Presents pre-tabulated statistics on specific sub-populations without requiring users to analyze raw data or know statistical formulas. • Estimates are presented by: • Geographic location • Age • Race/ethnicity • Gender • Year

Data sources • Total counts • Births (NVSS – Natality) • Deaths (NVSS – Mortality) • Population surveys • National Health Interview Survey (NHIS) • National Health and Nutrition Examination Survey (NHANES) • Behavioral Risk Factor Surveillance System (BRFSS)

Data sources (continued) • Health Care Surveys • National Hospital Discharge Survey (NHDS) • National Ambulatory Medical Care Survey (NAMCS) • National Hospital Ambulatory Medical Care Survey (NHAMCS)

Considerations • Data are analyzed before release. • Software being used cannot calculate precision estimates appropriately for surveys with complex sampling designs. • Estimates are 3-year averages. • Pooling gives the estimates greater precision. • Larger number of specific sub-groups estimates can be presented.

Considerations (continued) • Data are formatted into interactive data tables. • User can format as needed. • Timely updates of the data can be released on the Internet.

Data suppression • Relative standard error • (RSE) = (SE/estimate) * 100% • Data not shown when RSE > 30% • Sample size • Vital Statistics: suppression for < 20 events • Surveys: suppression for sample size < 25
