Grandparents came through for grandkids as the COVID-19 pandemic hit, with unexpected numbers of elders moving in or opening homes to about 460,000 children, said a Washington State University researcher. A study found these co-residences made up a majority in a 2020 surge of nearly 510,000 children in all pandemic-era "doubled up" residences. That meant kids and at least one parent lived with another adult who isn't a parent figure – grandparent, aunt, cousin or roommate. Mariana Amorim, a WSU sociology assistant professor and lead author, said mainly grandparents stepped in to provide a safety net for their families, particularly for six months beginning spring 2020.
