A “diaper district” is a neighborhood that is filled with many new families (especially those including diaper-age children).  The New York (NY) Times coined the name “Diaper District” in a February 20, 2009 article by Vivian S. Toy about families living in the financial district. (The headline now reads only “The Financial District Attracts Families” on the Internet version.)
 
The nickname “diaper district” is not an official one and could also apply to Park Slope or Williamsburg.

Upswing of Families in Financial District
By Jen Chung in News on February 22, 2009 2:33 PM
The financial firms may be doing poorly on Wall Street, but there’s a baby boom in the Financial District! The NY Times dubs the area the “Diaper District” and speaks to doormen at condo 80 John Street who say 22 babies were born to residents last year—“And we have about two or maybe three more expecting. There were so many, we lost count”—as well as parents who explain the migration—“A lot of people that I know from the group lived in rentals in TriBeCa and Battery Park City, and when it came time to buy, they couldn’t afford to stay where they were, but the Financial District offered more space for less money.

Downtown Growing Up
Tribeca’s Babylicious boutique is changing its name and expanding to serve an older clientele of children, a signal that the Lower Manhattan “baby boom is starting to age,” Downtown Express writes. The Diaper District is becoming Tweentown already? FiDi bodegas better start upping their Clearasil supplies.

Trendy Babies Taking Over Williamsburg?
by Anthony Longo on January 21, 2011
We all know that Brooklyn is getting cooler by the minute. Are we really going to put babies in the mix? Is Williamsburg going to be the next Park Slope, Carroll Gardens and Brooklyn Heights. Recently, a New York Times article was written about how Williamsburg is becoming baby friendly.  Or as Curbed NY called it “Diaper District.”
