Delaware residents may be interested in a study that looks at one phenomenon leading many to retire earlier than planned. This early retirement may be having unintended consequences, however. The Pew Research Center study revealed some surprising statistics about the number of women who are working after they become grandparents. According to the researchers, women who are age 58 to 61 are nearly 30 percent less likely to be working when they have grandchildren than when they don't. Those grandparents who are aged 51 to 54 are 21 percent less likely to be working than their grandchild-less counterparts.
