If you're a grandparent, Sunday is all about you. Grandparents Day, established by federal proclamation 33 years ago, calls on America to honor a segment of the population whose responsibilities in the rearing of grandchildren and the joys in spoiling them grow each year.
About 65 million Americans -- 20 percent of the population -- are grandparents.
The majority of grandparents are baby boomers.
10 percent of all children in the United States live with a grandparent.
The median household income for grandparents responsible for grandchildren under the age of 18 is $45,000.
The average age of a person becoming a grandparent for the first time is 47.
