What Type of Data Does the CDC Collect?


Larry Thompson

The Centers for Disease Control and Prevention (CDC) is a leading national public health agency in the United States. It plays a crucial role in collecting and analyzing data to understand and address various health-related issues. In this article, we will explore the type of data the CDC collects and how it contributes to public health.

What is Data Collection?
Data collection involves gathering information from various sources to gain insights and make informed decisions. The CDC collects data from different sectors, including healthcare facilities, laboratories, research studies, surveys, and more. This data helps identify patterns, trends, and potential threats to public health.

Types of Data Collected by the CDC

The CDC collects a wide range of data to monitor diseases, track outbreaks, assess risk factors, develop prevention strategies, and evaluate interventions. Here are some key types of data collected:

1. Disease Surveillance Data

The CDC tracks the occurrence and spread of diseases through its surveillance systems. These systems collect data on notifiable diseases (such as influenza or COVID-19), emerging infections, chronic conditions (like diabetes or cancer), injuries, birth defects, and environmental health hazards.

2. Vital Statistics Data

The CDC also collects vital statistics data through its National Vital Statistics System (NVSS).

This includes birth certificates, death certificates, marriage records, divorce records, fetal death reports, and other vital events. These data provide valuable information on population health indicators like mortality rates or causes of death.

3. Behavioral Risk Factor Surveillance System (BRFSS)

To understand behavioral risk factors associated with chronic diseases such as obesity or smoking-related illnesses, the CDC conducts the BRFSS survey. This telephone-based survey collects self-reported information on behaviors such as tobacco use, physical activity levels, dietary habits, preventive screenings utilization patterns.

4. National Health and Nutrition Examination Survey (NHANES)

The NHANES is a comprehensive survey that combines interviews, physical examinations, and laboratory tests to assess the health and nutritional status of the U.S. population. It collects data on various health conditions, including cardiovascular diseases, diabetes, nutritional deficiencies, and exposure to environmental toxins.

5. Environmental Health Data

To understand the impact of environmental factors on health, the CDC collects data related to air quality, water quality, hazardous substances exposure, and more. This information helps identify areas with increased risks and develop strategies for prevention and intervention.

  • Other Types of Data Collected by the CDC:
  • Surveillance data from healthcare-associated infections
  • Data on occupational health hazards
  • Data on emergency preparedness and response
  • Epidemiological studies data
  • Injury surveillance data

Why is Data Collection Important?

Data collection is crucial for several reasons:

1. Disease Monitoring: By collecting data on diseases and risk factors, the CDC can monitor changes in disease patterns over time, detect outbreaks early, and implement effective prevention measures.

2. Public Health Planning: The collected data helps public health officials develop evidence-based policies and interventions to improve population health outcomes.

3. Research and Evaluation: Researchers use CDC-collected data to conduct studies that further our understanding of diseases, risk factors, treatment outcomes, and preventive measures.

4. Resource Allocation: Data guides resource allocation decisions by identifying areas or populations with the greatest need for healthcare services or interventions.

In conclusion, the CDC collects a diverse range of data to better understand public health issues at both national and local levels. This robust collection of information enables researchers and policymakers to identify trends, implement effective interventions, and ultimately improve health outcomes for all.
