And who are the worst at saving for that rainy day?
Bankrate.com found people between 30 and 49 are more likely than any other age group to not have an emergency fund.
Here's something that surprised me about the latest savings results. Young adults are more likely to have at least five months of living expenses saved.
Yes, you read that right. The millennials, those aged 18 to 30 who we older folks complain are too entitled, are actually saving. But for good reason, says Greg McBride, Bankrate.com's chief financial analyst.
"They tend to have lower expenses," McBride said. "They don't have to put away as much because they are likely living at home with their parents or have roommates. People 30 to 49 are more likely to not have emergency savings because those are the years they have a house, two or three kids and a dog. But they need the emergency savings more than anybody."
It's not that people don't know they need to save, especially with the Great Recession a close memory.
"There has been an attitude shift," McBride said. "People recognize they don't have enough savings and know they aren't making progress. Savings is a consistent sore spot with consumers when it comes to financial security. But nothing helps you sleep better at night than knowing you have money tucked about in the event of unplanned expenses. Savings provides a critical buffer between you and high-cost debt or other financial distress."
Understandably, one obvious reason people don't have enough money saved is because they are struggling to cover their basic expenses.
But there's another barrier to saving.
"Americans have fallen out of the saving habit," according to a recent report by Oxford Economics sponsored by a group of financial and public-policy organizations.
Even before the recession, the savings rate in America was pitiful. It's better now at almost 4 percent but still not good enough.
"Projecting the current rate forward, and adjusting only for the aging of the population, we found that the saving rate will fall to an extremely low 3 percent in the 2030s," the report noted. "If Americans are not able to save a significant amount of financial capital, millions of working households will have to choose between working much longer, accepting a lower standard of living in retirement - or running out of money altogether."
I get so frustrated when people say they've saved up for their summer vacation even though they will admit to not having any emergency funds or very little. You aren't entitled to a vacation until you have a cushion for the things in life that happen - a major car repair, a broken air-conditioning system when the temperatures are reaching triple digits or a family emergency or death. You have to plan for the unexpected.
"Undersaving at the national level could also place the economy and government on an unsustainable path, marked by an ever-increasing external debt that could ultimately undermine financial stability," the Oxford Economics report said.
Are you alarmed now?
If not, you should be. We've got to become a nation of habitual savers, which is why I was so pleased to see so many young adults catching the savings fever early.
I've seen it with my own 19-year-old. She works during the summer and saves pretty much all she earns so she will have funds for the things she needs during the school year. This past year, her first year in college, she was always complaining that she didn't have any money. But she did. She had it in her savings, which she withdrew in a self-imposed monthly allowance.
"If you can start to save when your income is low and build the habit when income is low, it will stay with you as your income grows," McBride said.
If you are struggling with saving, consider what my grandmother "Big Mama" would always say to encourage me: "You have to save for a rainy day, because it's going to rain."
