Pediatric Asthma Prevalence by Demographic Characteristics in the United States

Survey data details asthma prevalence among children under 18 years old in the United States, broken down by characteristics like age. The dataset originates from the National Health Interview Survey conducted by the National Center for Health Statistics and was last updated in June 2025.

Use Cases

• Analyze trends in ESTIMATE of asthma prevalence over YEAR_NUM for different AGE groups.
• Model the relationship between demographic STUB_LABEL (e.g., gender, race) and asthma ESTIMATE using SE for uncertainty.
• Compare asthma INDICATOR values across different PANEL_NUM or STUB_NAME categories.
• Track changes in pediatric asthma rates (ESTIMATE) by UNIT_NUM across multiple HUS_YEAR survey periods.

Strengths

• Data sourced from the authoritative National Health Interview Survey (NHIS).
• Includes standard error (SE) for prevalence estimates.
• Contains multiple stratification variables (STUB_NAME, STUB_LABEL, AGE) for detailed breakdowns.

Limitations

• Sample size (row count) and total population coverage are unknown.
• Specific geographic granularity below national level (e.g., state) is unclear from provided columns.
• Data freshness depends on NHIS release cycles, with the latest update being administrative metadata.
