Participants Frequently Asked Questions

Survey Background

What is the National Survey of Children’s Health?

The National Survey of Children’s Health collects information on the physical and mental health and health care needs of children ages 0-17 years in the United States. This information can then be used by states and communities to make sure that children and their families have what they need to be healthy and thrive.

How long has the survey been going on?

The Health Resources and Services Administration’s Maternal and Child Health Bureau has been conducting national surveys about children’s health since 2001, when the first National Survey of Children with Special Health Care Needs was conducted to learn about how special health care needs impact American children and their families. The first National Survey of Children’s Health was conducted in 2003 to help states and communities better understand the health and well-being of all children. Starting in 2016, the survey is being conducted every year to collect information that is up-to-date and accessible to states and communities working to improve the health and well-being of children.

Why should I participate in the National Survey of Children’s Health?

The survey collects important information on the health and health care needs of American children 0-17 years old. Your participation provides critical information about children in your state and ensures that households like yours are fairly represented.

The results help families, communities, policymakers, child advocates, educators, researchers, and the general public better understand and respond to the health and health care needs of children and families.

Who sponsors the survey?

The U.S. Department of Health and Human Services, Health Resources and Services Administration, Maternal and Child Health Bureau – part of the federal government – sponsors and provides the primary funding and oversight for the survey.

How is the U.S. Census Bureau involved?

The U.S. Census Bureau conducts the survey.

Selection of Survey Participants

Why was I selected for the survey?

The U.S. Census Bureau chose your address, not you personally, from a scientifically selected sample from a list of ALL mailable addresses in the country. Only a sample is selected because surveying every address in the country would cost too much and take too long.

How was my address/household/child chosen?

The U.S. Census Bureau randomly selected your address from all mailable addresses in the nation using scientific sampling methods. The sample is designed so that information collected will accurately describe the health experiences of all children in the United States.

Do I have to participate?

No. However, your participation is very important because each person who answers the survey represents thousands of others. Not participating in the survey may mean that children like yours or those in your community will not be represented in the results. Many people find participating to be interesting and enjoyable. You may choose not to answer any question for any reason.

There are no children in my household. Do I still need to answer the survey?

Yes, even if there are no children in the home, we still need you to respond so that we can get accurate information about the number of children living in the United States.

Answering the Survey

What kinds of questions does the survey ask?

Survey topics include:

  • Child and family characteristics
  • Physical and mental health status, including current conditions and functional difficulties
  • Health insurance status, type, and adequacy
  • Access and use of health care services
  • Medical, dental, and specialty care needed and received
  • Family health and activities
  • Impact of child’s health on family
  • Neighborhood characteristics

How long will it take?

The first part of the survey contains a few questions to determine if you’re eligible to complete a more detailed questionnaire. This first part will take less than 5 minutes to complete. If your household is eligible for the second part of the survey, you will then be asked more detailed questions about one specific child within the household. This second part should take on average 33 minutes depending on your answers.

What if I do not know an exact answer to a question?

You can ask someone else in your household. They might know the answer. If no one knows or there is no one else in your household, please provide your best guess or estimate. If you need clarification on what a specific question is asking, please call the U.S. Census Bureau toll-free at 1-800-845-8241 or email us at

Why does the National Survey of Children’s Health ask such detailed questions?

Detailed information is collected because many of the child health challenges faced by families, communities, and states are complicated. In addition, the survey is the only source of information in the country on some health conditions and needs.
