Hi, i will like to know about Long Island please 
 Long Island is a large island in New York. It is the longest and largest island in the mainland United States. 
 I didn't know that , tell me more about its demographics 
 A 2010 article in The New York Times stated that the expansion of the immigrant workforce on Long Island has not displaced any jobs from other Long Island residents . 
 Any other fact on demographics 
 Long Island is home to some of the wealthiest communities in the United States , including The Hamptons , on the East End of the South Shore of Suffolk County ; the Gold Coast , in the vicinity of the island 's North Shore , along Long Island Sound ; and increasingly , the western shoreline of Brooklyn , facing Manhattan . 
 Very well. Can you tell me about their government 
 There are no direct facts to their government. But According to the U.S. Census Bureau 's 2008 American Community Survey , Nassau and Suffolk Counties had the 10th and 26th highest median household incomes in the nation , respectively . 
 Another fact about politics? 
 Sure. Nassau and Suffolk Counties are served by the Nassau County Police Department and Suffolk County Police Department , respectively , although several dozen villages and the two cities in Nassau County have their own police departments . 
 Thanks for all your help today 
 You're welcome
