Query: In recent years, the whote population has begun to move where?
Context: From the 1950s to the end of the 20th century, the proportion of non-Hispanic whites in the city declined; in 2000, non-Hispanic whites made up 49.5% of the city's population, making the city majority-minority for the first time. However, in recent years the city has experienced significant gentrification, in which affluent whites have moved into formerly non-white areas. In 2006, the US Census Bureau estimated that non-Hispanic whites again formed a slight majority.
