NHIS Adult Summary Health Statistics: Annual Estimates from the NCHS Data Query System

Annual estimates from the National Health Interview Survey (NHIS) for adults aged 18 years and over, covering a wide range of health topics. The data is provided by the National Center for Health Statistics (NCHS) via the Data Query System (DQS) and was last updated in September 2025. It includes statistical estimates, confidence intervals, and standard errors for various demographic and health-related subgroups.

Use Cases

• Analyzing health outcome disparities across SUBGROUP and GROUP classifications using ESTIMATE and STANDARD_ERROR.
• Modeling temporal trends in health topics using TIME_PERIOD and ESTIMATE_LCI/ESTIMATE_UCI confidence intervals.
• Categorizing and filtering health statistics by TOPIC, SUBTOPIC, and TAXONOMY_ID for specific research queries.

Strengths

• Includes confidence intervals (ESTIMATE_LCI, ESTIMATE_UCI) and STANDARD_ERROR for statistical reliability assessment.
• Structured with hierarchical classification columns (TAXONOMY, GROUP, SUBGROUP) for detailed breakdowns.
• Data is sourced from the authoritative National Health Interview Survey (NHIS) and managed by the NCHS.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
