By Bill Cary -- Tuesday, November 11, 2014 Nearly half of the households that move to Westchester in any given year come straight from the five boroughs of New York City, according to the most recent census data. And, increasingly, they are bringing with them the rich racial and ethnic diversity of the city. Hispanics, for example, make up 22 percent of the county's population, compared with 10 percent in 1980. They are a younger population, too. Latinos account for 27 percent of the children in Westchester, 17 percent in Rockland and 15 percent in Putnam. "It's not just the explosion in Hispanic immigration that is changing the face of Westchester, but the exodus of whites, especially ones who are 25-34 and 35-44," said Alexander Roberts, executive director of Community Housing Innovations in White Plains, a HUD-approved housing agency and advocate for affordable housing. "Nationally, the population of whites increased by 8.49 percent, while it declined by 2.49 percent in Westchester between 2000 and 2012." Read more.
