　　Hello again and welcome to As It Is from VOA Learning English! I'm June Simms in Washington.

　　Many cities around the world are experiencing population growth. And the list of megacities is expanding. Today we tell about the South African city of Johannesburg. For many young people, Johannesburg is an increasingly popular place to call home.

　　But first, we look at some changes taking place in New York -- the largest city in the United States. And we hear how those changes are affecting one of its neighborhoods.

　　Rising Land Values Remake New York's Chinatown

　　Rising land values have changed the Chinatown area of New York City. Chinatown has long been an important base for Chinese immigrants and their families. It has one of the largest populations of ethnic Chinese outside of Asia. But many are leaving the neighborhood because of the rising cost of housing. Chinatown is now becoming home to many whites and students.

　　The Asian American Legal Defense and Education Fund has its headquarters in New York. The group released a report earlier this year. It said there is a similar shortage of reasonably priced housing in Chinatowns in Boston and Philadelphia. The report found an increase in high cost housing and hotels. It also noted a decline in families and Asian businesses in these Chinatowns.

　　In New York, Mayor Bloomberg's policies are praised for a major decrease in crime. Many of his supporters say higher housing costs are evidence of a city's economic progress.

　　But in Manhattan's Chinatown those rent increases have already pushed many people out. Numbers from the 2010 Census suggest that about 17 percent of the Chinese people in the area have been displaced since 2000. That is about 6,000 people who have left the neighborhood.

　　Sun Meirong has been living in Manhattan's Chinatown since she first came to the United States from Fuzhou in 1990. She owns a restaurant near the center of Chinatown. She says she has seen a large decrease in customers, mostly Chinese immigrants.

　　"In the past, during the thanksgiving holiday for example, there were so many people on this street outside. You could not walk. But in the past three years nobody is on the street anymore. This is the change we see in Chinatown."

　　Sun says that many of her neighbors have been forced from their homes after building owners decided to repair and modernize the buildings.

　　"Houses have been renovated and after that they just get sold to developers without considering to give it to the people who were living there in the first place: immigrants. The U.S. is a country of immigrants, but many immigrants get here and do not have a place to live or cannot afford it."

　　For Sun, what is happening in Chinatown opposes the very ideals that America stands for.

　　Several organizations in Chinatown are fighting what they see as the destruction of their neighborhood.

　　Li Hua is a secretary of the Chinese Staff & Workers' Association. She says her group collected thousands of signatures in an effort to stop plans for new high price developments.

　　"We have been protesting against it in all venues possible. At public hearings, with the administration's planning department, to the city council. We had people participating at every step, not just a few but hundreds. But Bloomberg charged on, they just do not care."

　　New York recently elected a new mayor. Some are hoping for a change in housing policy. Mayor Bill de Blasio has promised to take action to increase reasonably priced housing in the city.
