What is this?

ParentData makes sense of the latest data about pregnancy and parenting, and, sometimes, COVID-19. It offers numbers and decision-making tools, spreadsheets, statistics, and phrases I claim to invent like “Safety Turducken” and “Situational Fluency.” If this is your jam, you’re in the right place. And I hope that, by reading, you’ll feel more empowered to make your own pregnancy and parenting choices.

If you’re here looking for something in particular, you can always search the archive to see if I’ve written about it before. And if not, feel free to suggest it here: Ask Emily. To connect with other parents, head to the Chatrooms.

If you have any questions about this newsletter or your subscription, contact us at ask@parentdata.org.

My husband and I are devotees of your books, your newsletter, and your Instagram. Thank you for being an incredible guide to our family and the third parent at the dinner table every night as we discuss the latest thing we’ve learned from you and from each other today.”

Why consider a paid subscription?

By paying, you’ll help me make the newsletter all I want it to be, with more features, tools, and support. In return, you’ll get an extra post each week, on Fridays. Sometimes it will be an advice column, others, it will be a follow-up on an earlier post or exclusive access to a live Ask-Me-Anything only for paid subscribers. You’ll also get access to the full ParentData archives, including some of my most popular posts. 

Please let me know if you want to be a part of the paid subscription but payment is prohibitive for you. You can send an email to ask@parentdata.org and we’ll be happy to comp your subscription.

Who are you?

It’s a good question! Here’s one version: I’m a professor of economics at Brown University. I’m also the author of three books on pregnancy and parenting — Expecting Better, Cribsheet, and The Family Firm. And I was named to the 2022 TIME 100 list of the most influential people in the world. You can learn more about me here.

And here’s the second version: I’m a mom of two kids who doesn’t sleep enough. I’m married to a great guy who puts up with all our business being turned into books and newsletters. I like to run. I think I’m funny, though my kids do not. Here’s a photo for that version, from a time I mistakenly took a run with too many bugs.

If you see yourself in any of this — or even if you don’t, but just like data-based parenting — I hope you’ll benefit from ParentData, and I hope you’ll consider subscribing.
