CDC Chronic Disease and Health Indicators Dataset

CDC Dataset Image

The CDC Chronic Disease and Health Indicators Dataset is a vital resource developed by the Centers for Disease Control and Prevention (CDC) to monitor and evaluate chronic diseases and health behaviors across diverse populations in the United States. The dataset provides detailed health statistics, including prevalence rates, mortality data, and health behaviors, offering a comprehensive view of chronic disease trends and associated health disparities.

Spanning over 310,000 records, with a focus on geographic and demographic stratifications, this dataset enables the examination of health trends over time and across populations. Indiana-specific data, comprising 5,624 records, highlights health outcomes at the state level, contributing to localized health assessments. This dataset is essential for understanding public health challenges and developing targeted interventions to improve health equity and outcomes nationwide.

Objective Section

Objective

To analyze the prevalence and trends of chronic diseases and health behaviors across various demographic groups, focusing on disparities related to age, sex, and race. This study provides:

  • Insights into temporal trends of chronic disease prevalence and associated health indicators.
  • A comprehensive understanding of health disparities among different population groups.
  • Data-driven perspectives to support public health interventions, inform healthcare policies, and promote equitable healthcare outcomes.

This analysis serves as a foundation for identifying critical public health priorities and fostering data-driven decision-making to enhance population health and well-being.

Methodology

Data Preparation: The CDC Chronic Disease and Health Indicators Dataset was processed to ensure data integrity and consistency. This included filtering Indiana-specific data, cleaning missing or invalid entries, and organizing the dataset into meaningful categories such as health topics, demographics, and time periods. Stratification columns (age, sex, race) were used to enable detailed demographic analysis, while geographic identifiers facilitated spatial insights.

Analysis:

  • Descriptive Analysis:

    Calculating averages, prevalence rates, and confidence intervals for chronic disease indicators across various demographic and geographic segments.

  • Temporal Trends:

    Assessing year-over-year changes in health indicators to identify patterns and progress in addressing chronic disease prevalence.

  • Stratification Analysis:

    Segmenting data by age, sex, and race to uncover disparities and highlight vulnerable populations.

  • Comparative Analysis:

    Comparing Indiana-specific data to broader national trends for benchmarking and localized health insights.

Visualization Section

Visualization:

Developing interactive visualizations to showcase key findings with the help of Tableau:

  1. Bar Charts for comparing average prevalence across health topics.
  2. Line Charts to illustrate trends in health indicators over time.
  3. Demographic-Specific Graphs for visualizing disparities by age, race, and sex.

These visualizations aim to make data insights accessible, actionable, and engaging for researchers, policymakers, and public health practitioners.
