A residential community of nearly 54,000, the population soars to more than 200,000 during the day as office workers, shoppers and visitors arrive by car, rail, bus and plane. White Plains is Westchester's premier business market and is home to the county's largest concentration of retail activity. With three major malls and the smaller White Plains Mall, and a dynamic and renewed downtown featuring pleasant stores, outstanding restaurants and nightlife, the White Plains economy benefits from more than $1.3 billion in annual retail sales.  Downtown White Plains has become a corporate hub attracting high technology firms, major corporations and investments from local universities.  With nearly 1,700 units of new residential housing under construction in the downtown, it will soon become a major residential neighborhood as well. White Plains is viewed by residents and visitors alike as one of the most attractive and desirable cities in the state in which to live, work, shop and play.
