Governing used interactive maps to measure the gentrification of the neighbourhoods of Boston (above) and 49 other cities as part of their report on gentrification in the United States last year. “While it has become much more prevalent, gentrification remains a phenomenon largely confined to select regions, not yet making its way into most urban areas. In the majority of cities reviewed, less than one-fifth of poorer, lower priced neighborhoods experienced gentrification. If all city neighborhoods are considered—including wealthier areas not eligible to gentrify—less than one of every ten tracts gentrified. Cities like Detroit, El Paso and Las Vegas experienced practically no gentrification at all.” [via]
