This dynamic map is a visual exploration of where New Yorkers moved in the last decade. It distills more than 4000 moves from over 1700 people, collected in an informal survey by WNYC, a New York based public radio station.
As most moves occurred from, to or within the New York area, this area is enlarged in the white circle at the center of the graphic. The rest of the world is mapped with a damped distance function, in order to fit everything into one screen without losing too much white space.
Each circle corresponds to one zip code area. Its size indicates the number of moves to or from the area. Actually, it is consists of two overlaid circles: a red one for people moving out of the area, and a blue one for people moving to the area. So, a small purple circle with a thick blue outline indicates a place where people tend to move and stay, whereas a red outline indicates a less attractive place.
