National Poll on Healthy Aging (NPHA) surveys are fielded twice per year using a sample of approximately 2,000 respondents ages 50–80 drawn from a nationally representative probability-based panel of U.S. households.

Starting with Wave 9 in August 2021, NPHA surveys are conducted using NORC’s AmeriSpeak® Panel. NPHA Waves 1-8 (April 2017-January 2021) were conducted using the Ipsos KnowledgePanel®.
