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.
It is important that all selected households respond to the survey to make sure that the experiences of all types of households and families are represented.

How was my address/household chosen?
The U.S. Census Bureau randomly selected your address from all mailable addresses in the country 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.
Go back to FAQ list
Why was only one child chosen?
A parent or adult caregiver is asked to complete the survey for one randomly selected child from each sampled household.
We select one child from each household to minimize the amount of time needed to complete the survey. The survey results are adjusted to represent the population of non-institutionalized children 0-17 years old.

How long has Health Resources & Services Administration (HRSA) Maternal & Child Health Bureau (MCHB) been conducting this survey?
HRSA MCHB first conducted the NSCH in 2003. MCHB also fielded the National Survey of Children with Special Health Care Needs (NS-CSHCN) in 2001, 2005-2006, and 2009-2010 to assess the prevalence and impact of special health care needs among children and their families in the U.S. The survey was redesigned in 2016 when HRSA MCHB combined content from both the NSCH and NS-CSHCN into a single survey known solely as the NSCH. The redesigned NSCH has been conducted annually since 2016.
