Is it safe to provide my information over the internet?

Your information is always encrypted. Our secure servers use "HTTPS," Hypertext Transfer Protocol over Secure Socket Layer, to ensure the encrypted transmission of data between your browser and the U.S. Census Bureau.

This means that instead of sending readable text over the Internet, both your browser and our server encode (scramble) all data using a security key. In addition to data being encrypted during transmission, all data are encrypted for protection when stored on the Census Bureau servers.

How do I recover my Web survey LoginID or PIN?

If you have lost or misplaced your Web Login ID and/or PIN, please call the U.S. Census Bureau toll-free at 1-800-845-8241 for assistance.

As noted in the letter you received requesting your participation, if you cannot complete the survey by Web, you may contact the U.S. Census Bureau at 1-800-845-8241 or for assistance. You can also contact us if you received a Web questionnaire invitation only and prefer to respond by paper.

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.

Participating in the NSCH helps families, communities, educators, researchers, policymakers, child advocates, and the general public better understand and respond to the health service needs of children and families. Your response also helps provide information for various federal and state programs that keep track of U.S. children's health, including the Title V maternal and child health program and the Healthy People 2030 initiative.

The information that you provide is used solely for statistical purposes. All U.S. Census Bureau employees take an oath of confidentiality and are subject to fines or imprisonment for improperly disclosing information. Names and addresses are removed from all forms, and are not included in any statistical release. Also, the NSCH NEVER asks for:

  • your Social Security number
  • your personal information via email
  • money or donations
  • credit card information

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.
