In 1970, Marian McQuade began a campaign to set aside a special day just for grandparents. In 1978, President Jimmy Carter signed the first presidential proclamation, designating the first Sunday after Labor Day as National Grandparents Day. The first official observance was Sept. 9, 1979, and has been celebrated every year since. In honor of our nation’s grandparents, the Census Bureau presents an array of data about the role they play in our lives.
