I've been engaged in an informal experiment lately that has been eye-opening (to me and perhaps some others) so I'm going to blow my cover and encourage you to try it too. After Parents published this story about child poverty in the U.S., I decided to make it a point to bring up the most noteworthy statistic from the piece as often as I could in casual conversation: One in five children in this country now live in a family where the total annual household income is below the federal poverty level of $23,550. One in five. In New York City, where I live, the number is actually closer to one in three. Which might explain why some people hardly blink when I share the fact. Others, however, are shocked. It can be very easy to get nose-down in our own little world and lose track of the larger one. But for all of us—and for our children--the future is at stake. Children living in poverty are at risk of troubles both physical and academic, starting with impaired brain growth and weak acquisition of language as babies and progressing right through to higher dropout rates, increased risk of both hunger and obesity and, eventually, diabetes and heart disease. Dr. Perri Klass, one of my all-time favorite writing doctors, makes the cost of childhood poverty upsettingly clear here. We can't change a problem if we're not aware of it, of course. So as we head into the Thanksgiving holiday, I challenge you to help raise awareness by also sharing the one-in-five fact. And then to look for ways to make a difference. In my case, our family lives close to the Harlem Children's Zone, so we both see what poverty looks like and help fight it by donating to the organization. And no matter how much or how little your own family has to give, we can all teach our kids how to appreciate what they do have--it's the first step to learning how to share our blessings with others.
